A protozoan disease caused in humans by four species of the PLASMODIUM genus: PLASMODIUM FALCIPARUM; PLASMODIUM VIVAX; PLASMODIUM OVALE; and PLASMODIUM MALARIAE; and transmitted by the bite of an infected female mosquito of the genus ANOPHELES. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high FEVER; SWEATING; shaking CHILLS; and ANEMIA. Malaria in ANIMALS is caused by other species of plasmodia.
Malaria caused by PLASMODIUM FALCIPARUM. This is the severest form of malaria and is associated with the highest levels of parasites in the blood. This disease is characterized by irregularly recurring febrile paroxysms that in extreme cases occur with acute cerebral, renal, or gastrointestinal manifestations.
Malaria caused by PLASMODIUM VIVAX. This form of malaria is less severe than MALARIA, FALCIPARUM, but there is a higher probability for relapses to occur. Febrile paroxysms often occur every other day.
A condition characterized by somnolence or coma in the presence of an acute infection with PLASMODIUM FALCIPARUM (and rarely other Plasmodium species). Initial clinical manifestations include HEADACHES; SEIZURES; and alterations of mentation followed by a rapid progression to COMA. Pathologic features include cerebral capillaries filled with parasitized erythrocytes and multiple small foci of cortical and subcortical necrosis.

Can anything be done to maintain the effectiveness of pyrethroid-impregnated bednets against malaria vectors? (1/6719)

Pyrethroid-treated bednets are the most promising available method of controlling malaria in the tropical world. Every effort should be made to find methods of responding to, or preventing, the emergence of pyrethroid resistance in the Anopheles vectors. Some cases of such resistance are known, notably in An. gambiae in West Africa where the kdr type of resistance has been selected, probably because of the use of pyrethroids on cotton. Because pyrethroids are irritant to mosquitoes, laboratory studies on the impact of, and selection for, resistance need to be conducted with free-flying mosquitoes in conditions that are as realistic as possible. Such studies are beginning to suggest that, although there is cross-resistance to all pyrethroids, some treatments are less likely to select for resistance than others are. Organophosphate, carbamate and phenyl pyrazole insecticides have been tested as alternative treatments for nets or curtains. Attempts have been made to mix an insect growth regulator and a pyrethroid on netting to sterilize pyrethroid-resistant mosquitoes that are not killed after contact with the netting. There seems to be no easy solution to the problem of pyrethroid resistance management, but further research is urgently needed.  (+info)

gammadelta T cells contribute to control of chronic parasitemia in Plasmodium chabaudi infections in mice. (2/6719)

During a primary infection of mice with Plasmodium chabaudi, gammadelta T cells are stimulated and their expansion coincides with recovery from the acute phase of infection in normal mice or with chronic infections in B cell-deficient mice (mu-MT). To determine whether the large gammadelta T cell pool observed in female B cell-deficient mice is responsible for controlling the chronic infection, studies were done using double-knockout mice deficient in both B and gammadelta cells (mu-MT x delta-/-TCR) and in gammadelta T cell-depleted mu-MT mice. In both types of gammadelta T cell-deficient mice, the early parasitemia following the peak of infection was exacerbated, and the chronic parasitemia was maintained at significantly higher levels in the absence of gammadelta T cells. The majority of gammadelta T cells in C57BL/6 and mu-MT mice responding to infection belonged predominantly to a single family of gammadelta T cells with TCR composed of Vgamma2Vdelta4 chains and which produced IFN-gamma rather than IL-4.  (+info)

Immunization of mice with DNA-based Pfs25 elicits potent malaria transmission-blocking antibodies. (3/6719)

Immunological intervention, in addition to vector control and malaria chemotherapy, will be needed to stop the resurgence of malaria, a disease with a devastating impact on the health of 300 to 500 million people annually. We have pursued a vaccination strategy, based on DNA immunization in mice with genes encoding two antigens present on the sexual stages of Plasmodium falciparum, Pfs25 and Pfg27, to induce biologically important antibodies that can block development of the parasite in the Anopheles mosquito and thus transmission of the disease. DNA encoding Pfs25 when administered by the intramuscular route, either alone or with DNA encoding Pfg27, had the most potent transmission-blocking effects, resulting in up to a 97% decrease in oocyst numbers in mosquito midguts and a 75% decrease in rate of infection. Immunization with DNA encoding a Pfg27-Pfs25 fusion protein was less effective and DNA encoding Pfg27 elicited antibodies in sera that had only modest effects on the infectivity of the parasite. These results show for the first time that DNA vaccination can result in potent transmission-blocking antibodies in mice and suggest that the Pfs25 gene should be included as part of a multicomponent DNA vaccine.  (+info)

Antimalarial activities of various 9-phenanthrenemethanols with special attention to WR-122,455 and WR-171,669. (4/6719)

Pilot appraisals of the activities of 16 specially selected 9-phenanthrenemethanols against acute infections with Plasmodium falciparum in owl monkeys showed that all were more active than the reference compound, WR-33,063. WR-122,455, the most active derivative, and WR-171,669, ranked sixth, were selected for study in human volunteers. To assist this undertaking, appraisals of both compounds in owl monkeys infected with various strains of P. falciparum were expanded. These assessments showed: (i) that WR-122,455 was four times as active as chloroquine against infections with chloroquine-sensitive strains and that WR-171,669 equalled chloroquine in activity; (ii) that these compounds were fully active against infections with strains resistant to chloroquine, pyrimethamine, or quinine, or to all three standard drugs; (iii) that the activity of WR-122,455 was a function of total dose, single doses being as effective as the same amounts delivered in three or seven daily fractions; and (iv) that a single dose of WR-122,455 conferred extended, although only partial, protection against challenges with trophozoites. Complementary experiments in rhesus monkeys inoculated with sporozoites of P. cynomolgi showed that the activity of WR-122,455 was limited to blood schizonts and did not extend to early or late tissue schizonts. These evaluations were compatible with the results of preliminary studies of the activities of WR-122,455 and WR-171,669 in human volunteers.  (+info)

Antimalarial activities of various 4-pyridinemethanols with special attention to WR-172,435 and WR-180,409. (5/6719)

Pilot appraisals of the activities of 10 specially selected 2,6-substituted-4-pyridinemethanols against acute Plasmodium falciparum infections in owl monkeys identified three derivatives that were two to three times as active as chloroquine against infections with a 4-aminoquinoline-susceptible strain and, at the same doses, were equally effective against infections with a strain fully resistant to treatment with maximally tolerated doses of chloroquine, quinine, and pyrimethamine. Two of these derivatives, WR-172,435 and WR-180,409, deemed worthy of evaluation in human volunteers, were studied in greater depth in owl monkeys infected with either the multidrug-resistant Smith strain of P. falciparum or the pyrimethamine-resistant Palo Alto strain of P. vivax. These studies showed (i) that at the same total oral dose, 3-day and 7-day treatment schedules were equally effective and slightly superior to a single-dose schedule; (ii) that WR-172,435 was slightly more active than WR-180,409 in each treatment regimen; (iii) that intravenous delivery of WR-180,409 phosphate was feasible and effective; (iv) that both compounds effected control of parasitemia more rapidly than any standard or newly discovered antimalarial drug; and (v) that WR-172,435 and WR-180,409 had therapeutic indexes at least four to eight times those exhibited by chloroquine in infections with 4-aminoquinoline-susceptible strains, indexes retained by these pyridinemethanols against infections with various drug-resistant strains.  (+info)

Suppression of lymphocyte transformation by plasma from owl monkeys acutely infected with Plasmodium falciparum. (6/6719)

Plasma collected from owl monkeys during the acute phase of Plasmodium falciparum infection was shown to adversely affect several in vitro responses which are considered to be correlates of cell-mediated immune functions of normal monkeys. In the presence of acute-phase plasma, response of normal monkey peripheral blood lymphocytes to stimulation with phytohemagglutinin, concanavalin A, and pokeweed mitogen was severely reduced, as was the ability of peripheral blood lymphocytes to respond to allogenic and xenogenic histocompatible antigens. The transformation response of peripheral blood lymphocytes from normal humans to phytohemagglutinin and concanavalin A was also suppressed. Since acute-phase plasma was not cytotoxic for peripheral blood lymphocytes, decreased responsiveness did not result from cell destruction. Acute-phase plasma appears to block initial steps in lymphocyte transformation.  (+info)

Evaluating the community education programme of an insecticide-treated bed net trial on the Kenyan coast. (7/6719)

Increased interest in the potential contribution of insecticide-impregnated bed nets (ITBN) to malaria control has led to research efforts to determine the impact and sustainability of ITBN programmes in differing environments. There is a need to develop effective, feasible educational strategies that will both inform and motivate community members, and thus maximize the correct usage of ITBN. This is especially true in communities where indigenous usage of bed nets is low. This paper describes the educational component of a randomized controlled community intervention trial of ITBN, with childhood malaria morbidity as an outcome. The educational approach and messages for the ITBN trial were developed from anthropological survey data collected 4 years before the trial, and from community surveys conducted by project researchers. Low levels of understanding amongst mothers of the aetiological link between mosquitos and malaria led to the exclusion of the term 'malaria' from the initial educational messages promoting the use of ITBN. Appropriate individuals within the existing district health care structure were trained as community educators in the project. These educators conducted intensive teaching in the community through public meetings and group teaching in the first 6 months of the trial. The impact of these initial activities was assessed through interviews with a random sample of 100 mothers and 50 household heads. This allowed the identification of messages which had not been well understood and further educational methods were chosen to address the areas pinpointed. The community assessment also demonstrated that, in 1994, over 90% of mothers understood a protective role for bed nets against malaria and the ITBN education messages were changed to take account of this. The school programme was evaluated through determining outreach (the number of households accessed), changes in participant children's knowledge, post-teaching assessment of mothers' knowledge and discussions with parent-teacher associations. It was shown that 40% of intervention homes with children in the target group were accessed, participant children learned the educational messages well (scores increased from a pre-teaching mean of 59% to a post-teaching mean of 92%) and a high level of awareness of the ITBN trial was achieved in these homes (75%). However, specific messages of the education programmed were not well transferred to the home (30%). The discussion emphasises the need for allocation of adequate resources for education in programmes dependent on achieving a change in community practices. We also describe the value of ongoing communication between programme planners and a target population in maximizing the effectiveness of messages and methods used.  (+info)

Implementing a nationwide insecticide-impregnated bednet programme in The Gambia. (8/6719)

Earlier studies in The Gambia suggested that the use of impregnated bednets might prove to be a useful malaria control strategy. Based on the results of these studies, in 1992 the Government of The Gambia was encouraged to initiate a National Impregnated Bednet Programme (NIBP) as part of the National Malaria Control Programme Strategy. This paper describes the implementation process/procedure of the NIBP. Evaluation results showed that, overall, 83% of the bednets surveyed has been impregnated, and 77% of children under the age of five years and 78% of women of childbearing age were reported to be sleeping under impregnated bednets.  (+info)

This map is a theoretical model based on available long-term climate data. Although it is reasonably accurate, it is not based on actual malaria data and may not reflect the real malaria status. It shows the theoretical suitability of local climatic conditions, and therefore the potential distribution of stable malaria transmission in the average year. Please note that climatic conditions, and therefore malaria transmission, vary substantially from one year to the next. Malaria control activities can also dramatically alter the malaria transmission situation. Where climate is suitable (red = 1), malaria is likely endemic (hypo-, meso-, hyper- or holoendemic). Suitable areas may have little or no malaria because of malaria control. Where climate is unsuitable (white = 0), malaria is likely epidemic or absent. Some unsuitable areas may actually have endemic malaria because of the presence of surface water in an area where there is little or no rain. In the marginally suitable areas (0.1 - ...
Land use and land cover changes, such as deforestation, agricultural expansion and urbanization, are one of the largest anthropogenic environmental changes globally. Recent initiatives to evaluate the feasibility of malaria eradication have highlighted impacts of landscape changes on malaria transmission and the potential of these changes to undermine malaria control and elimination efforts. Multisectoral approaches are needed to detect and minimize negative impacts of land use and land cover changes on malaria transmission while supporting development aiding malaria control, elimination and ultimately eradication. Pathways through which land use and land cover changes disrupt social and ecological systems to increase or decrease malaria risks are outlined, identifying priorities and opportunities for a global malaria eradication campaign. The impacts of land use and land cover changes on malaria transmission are complex and highly context-specific, with effects changing over time and space. Landscape
Malaria prevention and control strategies are being implemented robustly in the endemic provinces; however, similar strategies in the non-endemic provinces are lagging behind. This paper provides advice on the key measures for malaria prevention and management. Successful malaria treatment is dependent on a high index of suspicion for malaria in patients with acute febrile illness, and urgent treatment with effective medication.. Prevention of malaria. Travellers to malaria areas in southern Africa will be particularly vulnerable as the malaria risk season peaks in the coming months; therefore emphasis should be placed on prevention. Measures to avoid mosquito bites are the mainstay of malaria prevention and should be emphasised at all times. Whether or not appropriate chemoprophylaxis is warranted, should be determined by weighing up the risk of contracting malaria against the risk of adverse effects. Malaria risk is determined by travel location and accommodation, as well as season and length ...
Malaria is known to have significant effects on the body. This study, investigated the relation between platelet and haemoglobin levels of malaria positive and negative children (age range = 1-14 years). Out of the 1049 children (4.1± 3.3 years), comprising 493 females and 556 males who were tested for malaria parasites, the prevalence of malaria was 35.3%. Children aged one year with malaria recorded the least hemoglobin concentration of 8.0 ± 2.4g/dL. As the age of the children with malaria infection increase, the haemoglobin concentration also increased. The prevalence of anemia (,10 g/dL) in malaria infected children was 55.4% compared to 28.0% in children without malaria. Children with malaria infection were up to 4.0 (OR) times more likely to have severe anemia (,7 g/dL) than those uninfected. Furthermore, only 5.6% of malaria negative patients had thrombocytopenia (platelet ,150 ); while 49.5% of malaria positive children had thrombocytopenia. There was a significant weak positive ...
In China, the national malaria elimination programme has been operating since 2010. This study aimed to explore the epidemiological changes in patterns of malaria in China from intensified control to elimination stages. Data on nationwide malaria cases from 2004 to 2012 were extracted from the Chinese national malaria surveillance system. The secular trend, gender and age features, seasonality, and spatial distribution by Plasmodium species were analysed. In total, 238,443 malaria cases were reported, and the proportion of Plasmodium falciparum increased drastically from |10% before 2010 to 55.2% in 2012. From 2004 to 2006, malaria showed a significantly increasing trend and with the highest incidence peak in 2006 (4.6/100,000), while from 2007 onwards, malaria decreased sharply to only 0.18/100,000 in 2012. Males and young age groups became the predominantly affected population. The areas affected by Plasmodium vivax malaria shrunk, while areas affected by P. falciparum malaria expanded from 294
Malaria in pregnancy. It is estimated that approximately 50 million pregnant women globally are at risk of contracting malaria each year, and that 10 000 mothers and 200 000 infants die annually as a result of malaria in pregnancy.[1] Studies conducted in malarious areas of Africa have shown that the burden of malaria in pregnant women is higher than in non-pregnant women. In pregnancy malaria results in anaemia, low birth weight (LBW), prematurity, miscarriage, stillbirth, and perinatal and maternal deaths,[2-4] these complications being particularly severe in pregnant women co-infected with HIV.[5]. Control policy for malaria in pregnancy. The World Health Assembly in 2005 set targets of more than 80% coverage with all the recommended malaria interventions for pregnant women living in malaria endemic areas. These include indoor residual spraying (IRS) of insecticide for households at risk of malaria. Thirty-three of the 45 African countries that are endemic for malaria had implemented an ...
The quantification of malaria transmission for the classification of malaria risk has long been a concern for epidemiologists. During the era of the Global Malaria Eradication Programme, measurements of malaria endemicity were institutionalised by their incorporation into rules outlining defined action points for malaria control programmes. We review the historical development of these indices and their contemporary relevance. This is at a time when many malaria-endemic countries are scaling-up their malaria control activities and reconsidering their prospects for elimination. These considerations are also important to an international community that has recently been challenged to revaluate the prospects for malaria eradication.
What is Malaria? Malaria is an infectious disease characterized by colonization of red blood cells in our body by a parasite called plasmodium. Plasmodium is carried by female anopheles mosquito and it reaches into blood when this mosquito bites a human. Once the parasite enters the body, it multiplies in the liver and then affects the red blood cells.. Malaria is widespread in tropical and sub tropical regions of the world, where the anopheles mosquitoes thrive.. Agents of Malaria: Round 80% of malaria is caused by a parasite called Plasmodium falciparum which has a lifespan of 2 months. Other less common agents of malaria include Plasmodium vivax: ( 3 years, but less serious), Plasmodium Ovale: (3 years) and Plasmodium Malariae which is rare and mild form of malaria with a life span of 10 years or more. Variants of malaria include tertian fever, quartan fever and malignant tertian fever.. Malaria Incubation period: Malaria generally lasts for round 8 to 20 days (max 2 months) after the bite of ...
Ninety percent of malaria deaths occur in Africa and disproportionately affect pregnant women and young children. Approximately 125 million pregnancies occur each year in areas with P. falciparum and/or P. vivax malaria transmission; 10,000 of these women and 200,000 of their newborns will die as a result of malaria during pregnancy.Malaria in pregnancy (MIP) contributes to maternal anemia, maternal death, stillbirth, spontaneous abortion, and low birth weight.In areas of stable malaria transmission, babies are more likely to be small for gestational age, and in areas of unstable malaria transmission, they are more likely to be born preterm. One-third of all neonatal deaths in malaria endemic regions of Africa are due to low birth weight associated with P. falciparum infections during pregnancy. Key approaches to reduce the burden of malaria for pregnant women, their newborns and young children include: intermittent preventive treatment of pregnant women (IPTp) in areas of stable malaria ...
World Malaria Day is commemorated on April 25, the date in 2000 when 44 African leaders met in Abuja, Nigeria, and signed the Abuja Declaration, committing their countries to cutting malaria deaths in half by 2010. Malaria is a preventable and treatable parasitic disease transmitted by the female Anopheles mosquito. Malaria continues to cause approximately 1 million deaths worldwide each year, with nearly 90% of these deaths occurring among young children in Africa (1). This years theme for World Malaria Day is Counting Malaria Out, reflecting the countdown to achieve the 2010 goal of the Abuja Declaration. Since 2000, increasing numbers of partners and resources have rapidly increased malaria control efforts, and a consensus global action plan* has been written to guide a coordinated international effort to control, eliminate, and ultimately eradicate malaria. CDC contributes to malaria control through participation in the Presidents Malaria Initiative (PMI), a U.S. government interagency ...
In the past decade, the massive scale-up of insecticide-treated bed nets (ITNs) and indoor residual spraying (IRS), together with the use of artemisinin-based combination treatments, have led to major changes in malaria epidemiology and vector biology. Overall malaria prevalence and incidence have been greatly reduced worldwide [1]. But the reductions in malaria have not been achieved uniformly; some sites have experienced continued reductions in both clinical malaria and overall parasite prevalence [2-6], while other sites showed stability or resurgence in malaria despite high coverage of ITNs and IRS [7-12]. Persistence and resurgence of vector populations continues to be an important issue for malaria control and elimination [12-16]. More importantly, extensive use of ITNs and IRS has created intensive selection pressures for malaria vector insecticide resistance as well as for potential outdoor transmission, which appears to be limiting the success of ITNs and IRS. For example, in Africa, ...
All three trials separately found that the chances becoming infected with malaria were reduced by up to 85 per cent when intermittent preventive treatment in children (IPTc) was combined with the use of insecticide-treated bednets (ITNs), the main tool currently used to protect people against malaria in sub-Saharan Africa.. The three studies are published this week in the journal Public Library of Science (PLoS) Medicine. The studies provide further evidence to support IPTc being integrated into programmes designed to control malaria, particularly in areas that seriously affected by a higher rate of malaria infection during warm periods of the rainy season.. Previous clinical trials have shown that seasonal IPTc, which involves the administration of two or three doses of antimalarial drugs during the high malaria transmission season, has successfully reduced the number of people suffering malaria. Sleeping underneath ITNs has been shown to prevent malaria by 50 per cent, however these are the ...
This study confirms the high burden of malaria among tribal pregnant women in a chronic conflict corridor in India. It also shows that the burden of malaria among pregnant women varies according to seasonal patterns, being even more relevant during the high malaria season from October to March. In addition, it indicates that malaria infections among pregnant women in this area present a high risk, as the risk of malaria infection in pregnancy is especially high during first and second pregnancies [15]. More than 50% of pregnant women presenting for ANC care in this setting are in the first and second pregnancies.. Most malaria cases identified (99%) were caused by P. falciparum (isolated or mixed with other forms of malaria) which may add substantial risk to the patients. This finding is aligned with the results of other studies on malaria transmission dynamics made in this region in the past decades. Those studies show that in forested tribal areas in this region, malaria transmission seems to ...
QUESTION. What are the causes of malaria?. ANSWER. Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken on an infected person. When a mosquito bites an infected person, a small amount of blood is taken in which contains microscopic malaria parasites. About 1 week later, when the mosquito takes its next blood meal, these parasites mix with the mosquitos saliva and are injected into the person being bitten.. Because the malaria parasite is found in red blood cells of an infected person, malaria can also be transmitted through blood transfusion, organ transplant, or the shared use of needles or syringes contaminated with blood. Malaria may also be ...
INTRODUCTION: Malaria and HIV-1 infection cause significant morbidity and mortality in children in sub-Saharan Africa. Recurrent malaria infection increases HIV-1 viral load in adults and increases the rate of progression of HIV-1 infection to AIDS. The effect of malaria on viral loads in children living with AIDS (CLWA) is not clearly known. METHODS: One hundred thirty five afebrile HIV-1 positive children having negative blood slides for malaria were recruited at Apac Hospital and followed up for one year. They were monitored for development of Plasmodium falciparum malaria, which was treated with chloroquine (CQ) + sulfadoxine-pyrimethamine (SP) and the children followed up for 28 days. HIV-1 viral loads were measured over three time-points: at enrolment (no malaria), during an episode of malaria, and at a visit about 8 weeks (range 6-19 weeks) after the malaria visit when the child had neither parasites nor any intervening malaria episodes (post-malaria). Primary analyses were restricted to children
World Malaria Day (WMD) is an international day which is celebrated every year on 25th April and recognizes global efforts to control malaria. World Malaria Day was established in May 2007 by the 60th session of the World Health Assembly, WHO decision-making body. The day was established to provide education and understanding of malaria and spread information on year-long intensified implementation of national malaria-control strategies, including community-based activities for malaria prevention and treatment in endemic areas. World Malaria Day allows for corporations, multinational organizations and grassroots organizations globally to work together to bring awareness to malaria and advocate for policy changes.. Since 2000, malaria affected countries and their development partners have made remarkable progress in reducing the total number of malaria cases and death. But the toll of malaria remains unacceptably high. Every two minutes, a child dies of this preventable and treatable disease, ...

Malaria is commonly transmitted by mosquitoes which has a free breeding environment in Africa including Nigeria. According to the World Health Organisation, WHO, 438,000 deaths from malaria occurred in 2014 and that more than two thirds (70 percent) of all malaria deaths are to children under 5, even though malaria is a preventable, treatable disease. Many Nigerians often take malaria for granted and would totally ignore every symptoms. \it is important know all you need to know about the disease, INFORMATION NIGERIA in this piece brings you 10 interesting facts about it…. - Malaria is caused by Plasmodium parasites that are spread to people through the bites of infected Anopheles mosquito vectors. Of the 5 parasite species that cause malaria in humans, Plasmodium falciparum is the most deadly.. - Malaria breeds mostly in warmer climates, where there is an abundance of humidity and rain.. - Approximately 3.2 billion people are at risk of malaria. In 2015, there were an estimated 214 million ...
Children in malaria endemic areas acquire immunity to severe malaria faster than to mild malaria. Only a minority of children suffers from severe malaria and it is not known what determines this. The aim of this study was to establish how P. falciparum infections during the first years of life affect the risk of severe malaria. A matched case-control study was nested within a large birth cohort set up to study the immunoepidemiology of pneumococci on the Kenyan coast. Infection patterns in three-monthly blood samples in cohort children admitted to hospital with severe malaria were compared to controls matched on age, residential location and time of sampling. P. falciparum detected at least once from birth conferred an increased risk of severe malaria and particularly if multiclonal infections, as characterized by genotyping of a polymorphic antigen gene, were ever detected. The results show for the first time that children with severe malaria have more infections early in life compared to community
In the province of Palawan, the Philippines, malaria remains in peripheral regions. To accelerate the efforts to eliminate malaria in these regions, a community-based malaria control program was established in 1999.. This program, which is called Kilusan Ligtas Malaria (Tagalog for Movement Against Malaria), involved training 344 inhabitants as malaria microscopists (one microscopist per malaria-endemic village).. The utilization of community health workers including the microscopists has been proposed to overcome the recognized paucity of human resources and health systems.. This utilization was proved to be a potentially inexpensive, effective, and sustainable approach to bring malaria diagnosis and treatment closer to the affected households.. The microscopists in Palawan diagnose malaria in febrile patients via microscopy and prescribe first-line anti-malarial drugs to these malaria-infected patients.. The microscopists also implement community awareness-raising activities (CARA) that aim to ...
The disease malaria took about 445,000 lives in 2016 and infected about 216 million people, according to the World Health Organization (WHO). Malaria is transmitted by female mosquitoes and can eventually be fatal. The WHO fact sheet on malaria said that several groups were more susceptible to malaria, such as infants, children under age 5, and pregnant women. Although malaria may sound very terrifying, it is perfectly curable. As a matter of fact, some places have completely eliminated malaria. For example, according to the CDC, the United States eliminated malaria in the early 1950s. Most of Europe, Australia, and a few Asian, South American, and African countries were also declared malaria-free. So why is the death count still so high?. Well, despite the fact that malaria has been eliminated in most developed countries, it is still widespread in less developed countries. For example, according to the WHO factsheet on malaria, the WHO African Region carried about 90% of malaria cases and 91% ...
Background: Recently, there has been mounting interest in scaling-up vector control against malaria in Africa. It needs to be determined if indoor residual spraying (IRS with DDT) will provide significant marginal protection against malaria over current best practice of long-lasting insecticidal nets (LLINs) and prompt treatment in a controlled trial, given that DDT is currently the most persistent insecticide for IRS. Methods: A 2 armed cluster-randomised controlled trial will be conducted to assess whether DDT IRS and LLINs combined provide better protection against clinical malaria in children than LLINs alone in rural Gambia. Each cluster will be a village, or a group of small adjacent villages; all clusters will receive LLINs and half will receive IRS in addition. Study children, aged 6 months to 13 years, will be enrolled from all clusters and followed for clinical malaria using passive case detection to estimate malaria incidence for 2 malaria transmission seasons in 2010 and 2011. This ...
Intermittent preventive treatment (IPT) against malaria is a malaria control strategy aimed at reducing the burden of malaria in certain high-risk groups, namely pregnant women and children. Three strategies - IPT in pregnancy (IPTp), infants (IPTi) and children (IPTc) - are reviewed here focusing on the mechanism of action, choice of drugs available, controversies and future research. Drugs for IPT need to be co-formulated, long acting, safe and preferably administered as a single dose. There is no obvious replacement for sulfadoxine-pyrimethamine, the most commonly utilized drug combination. All strategies face similar problems of rising drug resistance, falling malaria transmission and a policy shift from controlling disease to malaria elimination and eradication. IPT is an accepted form of malaria control, but to date only IPTp has been adopted as policy.. ...
Malaria Reports is a peer-reviewed international medical journal devoted entirely to the study diagnosis, and treatment of malaria. The journal covers all aspects of malaria, including the pathophysiology, diagnosis, classification, epidemiology, and treatment of malaria for physicians and medical scientists. The journal tries to attract papers on malaria in its broadest sense. The journal welcomes papers that:. - provide malaria burden estimates and ways to improve the burden estimation (i.e. using optimal diagnostic tests).. - provide a better understanding of malaria, especially explaining the complex interaction between humans, vectors, climate and the environment. Studies incorporating e.g. socio-economic determinants are strongly encouraged. In line with this objective, we will appreciate papers reporting on interventions against malaria and clinically relevant information that will directly improve the care of patients with malaria.. - report on existing malaria information systems and ...
Successful malaria control depends heavily on efficacious anti-malarial drugs for the treatment of malaria. Artesunate-containing Combination Treatments (ACT) are increasingly recommended as first line malaria treatment in endemic countries, but implementation of this recommendation is limited by the small number of available and affordable co-formulated anti-malarial drugs. In recent years Intermittent Preventive Treatment has been recommended for malaria control in pregnancy and has been shown to be of potential public health importance in the prevention of malaria and anaemia in children. The use of drugs for malaria treatment or prevention is associated with the development of resistance and recent advances in molecular biology facilitate the evaluation of the impact on drug resistance of new drug-based strategies. This review concentrates on the challenges surrounding the use of ACT, the current understanding of IPT in infants and the use of molecular approaches to enhance our understanding ...
Dorothy Ibrahim is a rural health worker of many years standing. She is a proud contributor to the fight against malaria in the rural settlement of Gauraka, just outside Abuja in Niger State. Nigeria is one of the worlds most malaria endemic countries, accounting for approximately a quarter of all deaths from the disease worldwide. Kolo Yakubu, Senior Technical Malaria Officer at Malaria Consortium in Nigeria, spoke to Dorothy about her role as a rural health worker and the impact that SuNMaP - Support to National Malaria Control Programme - a partnership programme led by Malaria Consortium, has had on her role.. Youve been working for many years in this area. What changes have you seen during that time?.

Previous studies identified an allelic variant of the IL4 promoter region (IL4-589T) that appears to enhance the transcriptional activity of IL4, and is associated with increased IgE levels. Total serum IgE levels are elevated in malaria endemic regions, and higher in children with severe malaria. Here, we investigated the relationship of the IL4-589C/T polymorphism with severity of the disease in a case-control study of severe malaria in Burkina Faso, West Africa. No association between the IL4-589T and severe malaria was observed. No difference in Plasmodium falciparum-specific IgE was detected between severe and uncomplicated malaria patients. Among children with severe malaria, total IgE levels were significantly elevated in those carrying the IL4-589T allele (P = 0.018). In children with uncomplicated malaria, no significant difference was found. These results raise the possibility that there is a relationship between susceptibility to severe malaria, IgE production and genetic variation in the IL4
The study was about factors influencing malaria morbidity in Goma Sub County which is located in Mukono district. The main objective was to find out the relationship between social factors (settlement pattern, distance to bushes, distance to breeding places, income spent on malaria treatment and controls) and malaria morbidity. Specifically, the study looked at the effect of demographic factor (gender) on malaria morbidity and assessed the malaria prevention strategies. A simple random sample of 398 households based on three multi-stage sampling method at parish, village and household levels was used in the study. The variables in this research were analyzed at univariate, bivariate and multivariate levels. Under multivariate analysis, the binary logistic regression was ran for occurrence of malaria morbidity against all other variables. The following variables sex, settlement pattern, proportion of household income spent on malaria controls, distance to bushes, distance to breeding places, use ...
Malaria is an infectious disease caused by one of the plasmodia species that breed in the female anopheles mosquito. Plasmodium falciparum is the most severe and prevalent in Sub-Saharan Africa. Despite the fact that Malaria is a preventable and curable disease, it is endemic in over 90 countries. According to the latest estimates in the World Malaria report of 2014, 198 million cases occurred globally in 2013, and the disease led to over 500,000 deaths. The report also estimated international and domestic funding for malaria control and elimination for 2013 to be $2.7 billion. Even though malaria is a global disease, the burden is heaviest in the African region where 90% of malaria deaths occur. Since 1955, global health organizations have doubled their efforts for funding, vaccine development and, research, in an effort to eradicate malaria. However, the efforts in Sub-Saharan Africa region have been met with challenges like vector control, the changing epidemiology of malaria, donor fatigue, ...
I am pleased to announce our latest research project: my staff and I are participating in the following very important initiative.. 3 Day Malarone Acceptability and Tolerability research project (3MAT). Malaria is one of the most common causes of fever in Australian travellers, with approximately 400 cases reported each year in Australia. Most travellers who develop malaria did not take anti-malarial medications, or did not take the medications properly (e.g. forgot to take tablets). Malaria is a serious illness and can potentially be fatal.. A research project is being conducted with the aim to make it easier and cheaper to take malaria pills and thus reduce the risk of malaria in travellers. Malarone is a safe and effective anti-malarial medication. The standard dosage of Malarone for prevention of malaria is one tablet per day, starting 2 days before travelling to a malaria area, daily while in a malaria area, and continuing until 7 days after leaving the malaria area.. Research has shown ...
Local understandings of malaria and use of preventive measures-are critical factors in sustained control of malaria. This study assessed caretakers knowledge on malaria, use of Long Lasting Insecticide Treated Nets (LLINs) and care-seeking behavior for their childrens illness in different malaria transmission settings of Ethiopia. Data were collected from 709 caretakers of children of 2-9 years of age during in 2016. A standard questionnaire was used to assess caretakers perceptions of malaria, use of LLIN and care seeking behavior for febrile illness of children aged 2-9 years. The caretakers recognized malaria mostly by chills (70.4%, 499/709), fever (45.7%, 324/709) and headache (39.8%, 282/709). Overall, only 66.4% (471) of the caretakers knew that mosquito bite caused malaria and that it was quite heterogeneous by localities (ranging from 26.1% to 89.4%) and altitude (p | 0.05). Majority, 72.2% (512), of the caretakers knew that sleeping under LLIN could prevent malaria. Overall knowledge on
Malaria and HIV are two of the most important Infectious diseases worldwide that are overlapping and synergistic in sub-Saharan Africa. Despite the scale up of front line prevention efforts, the burden of malaria remains staggering among pregnant women and children; and malnutrition and growth retardation are major threats to child health. The purpose of the Prevention of Malaria and HIV Disease in Tororo (PROMOTE) program project (POI) is to evaluate promising interventions to reduce the burden of malaria and HIV and Improve maternal-child health through hypothesis based intervention studies. PROMOTE II will test the hypotheses that a) enhanced malaria chemoprevention in HIV infected and uninfected pregnant women will reduce placenta malaria; b) enhanced chemoprevention provided during both pregnancy and childhood will reduce malaria in children in the first 2 years of life and c) limiting in utero exposure to malaria antigens with enhanced malaria chemoprevention during pregnancy will reduce ...
In humans, malaria causes fevers, liver problems, breathing issues, and death. Malaria also leads to billions in economic impact in the areas in which it is present. These impacts include lost productivity and earning power of those afflicted or killed by malaria, the health investments needed to combat malaria, and tourism being deterred by a fear of malaria.. In 2018, more than 228 million cases of malaria were recorded and over 400,000 people around the world died from it.. The majority of the most common mosquito vectors of malaria (all species within the Anopheles genus) live and thrive in Africa, particularly sub-Saharan Africa. Its possible that they have evolved alongside humans during mankinds long history in Africa to become even more efficient at transmitting malaria.. Until recently, most of the malaria outbreaks in sub-Saharan Africa had been in rural or semi-rural areas.

Malaria is highly prevalent in many parts of India and the Indian subcontinent. Mangaluru, a city in the southwest coastal region of Karnataka state in India, and surrounding areas are malaria endemic with 10-12 annual parasite index. Despite high endemicity, to-date, very little has been reported on the epidemiology and burden of malaria in this area. A cross-sectional surveillance of malaria cases was performed among 900 febrile symptomatic native people (long-time residents) and immigrant labourers (temporary residents) living in Mangaluru city area. During each of dry, rainy, and end of rainy season, blood samples from a group of 300 randomly selected symptomatic people were screened for malaria infection. Data on socio-demographic, literacy, knowledge of malaria, and treatment-seeking behaviour were collected to understand the socio-demographic contributions to malaria menace in this region. Malaria is prevalent in Mangaluru region throughout the year and Plasmodium vivax is predominant ...
Malaria is a protozoal disease transmitted by the Anopheles mosquito, caused by minute parasitic protozoa of the genus Plasmodium, which infect human and insect hosts alternatively. There are four species of the genus plasmodium responsible for the malaria parasite infections that commonly infect man, P.falciparum, P.vivax, P.malariae and P.ovale. The most important of these is P.falciparum because it can be rapidly fatal and is responsible for the majority of malaria related deaths. Malaria effects mainly poor, underserved and marginalized populations in remote rural areas which are characterized by inadequate control measures and limited access to health care. Higher malaria prevalence has been reported among ethnic and tribal groups living in remote forested and border areas. Treatment for Malaria is primarily aimed at personal protective measures that prevent mosquitoes from biting and transmitting malaria, chemo-prophylaxis, anti-malarial drug of choice and blood schizonticides are the ...
BACKGROUND. Malaria is the leading cause of morbidity and mortality in Ethiopia, accounting for over five million cases and thousands of deaths annually. The risks of morbidity and mortality associated with malaria are characterized by spatial and temporal variation across the country. This study examines the spatial and temporal patterns of malaria transmission at the local level and implements a risk mapping tool to aid in monitoring and disease control activities. METHODS. In this study, we examine the global and local patterns of malaria distribution in 543 villages in East Shoa, central Ethiopia using individual-level morbidity data collected from six laboratory and treatment centers between September 2002 and August 2006. RESULTS. Statistical analysis of malaria incidence by sex, age, and village through time reveal the presence of significant spatio-temporal variations. Poisson regression analysis shows a decrease in malaria incidence with increasing age. A significant difference in the ...
In Brazil, malaria transmission is mostly confined to the Amazon, where substantial progress has been achieved towards disease control in the past decade. Vector control has been historically considered a fundamental part of the main malaria control programs implemented in Brazil. However, the conventional vector-control tools have been insufficient to eliminate local vector populations due to the complexity of the Amazonian rainforest environment and ecological features of malaria vector species in the Amazon, especially Anopheles darlingi. Malaria elimination in Brazil and worldwide eradication will require a combination of conventional and new approaches that takes into account the regional specificities of vector populations and malaria transmission dynamics. Here we present an overview on both conventional and novel promising vector-focused tools to curb malaria transmission in the Brazilian Amazon. If well designed and employed, these new vector-based approaches may improve the implementation of
An analysis is presented of continuous data collected over 11 years based on 1 902 600 person/days of observation on the malaria experience of the people of Daraweesh, a village in eastern Sudan. Malaria transmission is hypo-endemic: the acquisition of clinical immunity with age is not as obvious as in more holo-endemic areas and malaria remained a problem in all age groups throughout the study. However, this population, who are of Fulani origin, showed a distinctly variable level of disease susceptibility. Thirty-two percent of the village never reported malaria symptoms or required malaria treatment while others experienced up to 8 clinical episodes over the 11 years of observation. Malaria incidence was clearly influenced by drought but much less obviously by rainfall. To what extent outbreak patterns are explicable in terms of anopheline factors, and to human immune factors, remains an interesting question for malaria modelling in this, and in other low transmission zones, such as the ...
Sleeping under an insecticide-treated bednet (ITN) and spraying homes with insecticides are effective ways to prevent malaria in most countries affected by malaria.. While 54% of people at risk in sub-Saharan Africa slept with an ITN compared to 30% in 2010, the increase in coverage has slackened since 2014, according to the report.. The report also noted a decline in the number of people protected by insecticides, from an estimated 180 million in 2010 to 100 million in 2016. The largest decreases were noted in the African Region.. Read More: The UK Is Investing £45 Million to End Malaria in Uganda. In 2016, there was an estimated US$ 2.7 billion invested in malaria efforts worldwide, but the annual amount needed by 2020 to successfully reach the 2030 targets of WHOs malaria strategy is US $6.5 billion.. The WHO Global Technical Strategy for Malaria outlines a 40% decrease in malaria cases and mortality rates by the year 2020.. Meeting the global malaria targets will only be possible through ...
The injectable vaccine, RTS,S, was developed to protect young children from the most deadly form of malaria caused by Plasmodium falciparum. RTS,S will be assessed in the pilot programme as a complementary malaria control tool that could potentially be added to the core package of WHO-recommended measures for malaria prevention.. The prospect of a malaria vaccine is great news. Information gathered in the pilot programme will help us make decisions on the wider use of this vaccine, said Dr Matshidiso Moeti, WHO Regional Director for Africa. Combined with existing malaria interventions, such a vaccine would have the potential to save tens of thousands of lives in Africa, she added.. Africa bears the greatest burden of malaria worldwide. Global efforts in the last 15 years have led to a 62 percent reduction in malaria deaths between 2000 and 2015, yet approximately 429,000 people died of the disease in 2015, the majority of them young children in Africa.. The WHO pilot programme will assess ...
Malaria remains a major global health burden, killing hundreds of thousands annually, especially in sub-Saharan Africa. In 2019, a Phase IV Expanded Programme on Immunization (EPI)-linked malaria vaccine implementation was underway. However, in December 2019, a novel pneumonia condition termed coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with many clinical, epidemiological, and biological parallels to malaria, was reported in Wuhan, China. COVID-19 is spreading rapidly, and, as of the 3rd of June, 2020, more than 382,507 persons had died from COVID-19. Children under 5 years who suffer high malaria-attributable mortalities are largely asymptomatic for COVID-19. Considering that the malaria burden is highest in low-income tropical countries with little capacity to fund malaria control and eradication programs, the fight against malaria in these regions is likely to be hampered. Access to healthcare has generally been limited, while malaria
According to the recent World Malaria Report 2015, around 234 million people are at high risk of malaria in Southeast Asia. The region accounted for 10 percent of global malaria cases and seven percent of deaths in 2015.. There are two types of malaria that cause the most concern in the region - and both can be deadly. Seventy-four percent of P. vivax malaria cases occur in Southeast Asia. P. falciparum resistance to artemisinin, the most effective treatment, is also of grave concern in the region and has now been detected in five countries in the Greater Mekong Subregion (GMS): Cambodia, Lao Peoples Democratic Republic, Myanmar, Thailand and Vietnam.. Malaria can be transmitted by biting mosquitoes during indoor and outdoor activities. However, current malaria vector control policy relies almost entirely on methods that address indoor feeding and resting mosquitoes through indoor residual spraying and insecticide treated mosquito nets. National malaria control programmes are finding that ...
Malaria is a mosquito-borne infectious disease affecting humans and animals caused by parasitic protozoan belonging to the plasmodium family. Malaria is typically transmitted from human to human through the bite of an infected Anopheles (female) mosquito. Symptoms of malaria include fever, headache, fatigue, muscle pain, diarrhea, anemia, and vomiting. Severe malaria can cause yellow skin, seizures, coma, or death. Cerebral malaria is a form of severe malaria. Cerebral malaria has high mortality rate and can cause various complications in the neurology.. Cerebral malaria causes CNS manifestations which includes any degree of impaired consciousness, abnormal neurological signs, delirium, and focal and generalized convulsions. Causes of neurological manifestations in cerebral malaria are due to high-grade fever, anti-malarial drugs, hypoglycemia, hyponatremia, and severe anemia. Patients of cerebral malaria exhibit symptoms such as nystagmus, seizures, or fall into coma. Artemisinin derivatives ...
Controlled human malaria infection (CHMI) is a critical component of malaria vaccine and drug development and is an important element of any strategy for accelerating the development of new tools for malaria control, elimination and eradication. Until now, CHMI has been performed in malaria naïve subjects from countries not endemic for malaria using both infectious mosquitoes and recently, aseptic, purified, cryopreserved Plasmodium falciparum sporozoites (PfSPZ). Results from these studies report significant infection success in all study subjects and an excellent safety profile.. The conduct of CHMI studies in malaria endemic populations will allow early understanding of responses to new vaccines and drugs in endemic country populations and for direct comparisons between previously exposed and non-exposed individuals. Performing CHMI studies in malaria endemic countries will reduce associated costs, speed-up the process of testing and substantially contribute to the acceleration of the ...
TY - JOUR. T1 - Malaria-specific antibody responses and parasite persistence after infection of mice with Plasmodium chabaudi chabaudi. AU - Achtman, A. H.. AU - Stephens, Robin. AU - Cadman, E. T.. AU - Harrison, V.. AU - Langhorne, J.. PY - 2007/9. Y1 - 2007/9. N2 - While it is known that antibodies are critical for clearance of malaria infections, it is not clear whether adequate antibody responses are maintained and what effect chronic infection has on this response. Here we show that mice with low-grade chronic primary infections of Plasmodium chabaudi or infections very recently eliminated have reduced second infections when compared with the second infection of parasite-free mice. We also show that parasite-specific antibody responses induced by infection of mice with Plasmodium chabaudi contain both short- and long-lived components as well as memory B cells responsible for a faster antibody response during re-infection. Furthermore, parasite-specific antibodies to the C-terminal fragment ...
Seasonal migrant and permanent laborers who are working in big mechanized agricultural farms in Metema - Humera lowlands are not included in Ethiopia Malaria Elimination Program. The aim of this research was to show the high confirmed and treated malaria cases in these laborers. A retrospective analysis of the confirmed and treated malaria cases in all the districts of West, Central and North Gondar Zones, using Weekly Public Health Emergency Management (PHEM) reports, was conducted to show a complete picture of the malaria incidences in the areas. A total of 3,485,646 confirmed malaria cases were treated in Amhara region during 2013 to 2017. Of the total malaria cases in the Amhara region during these period, 1, 286, 848 cases or 37.2% were originated from West, Central and North Gondar Zones. But these 3 Zones contribute only 17% of Amhara region population. Of all the confirmed malaria cases reported in the 3 Zones, 41.7% (536,749/1286, 848) was reported from the three lowland districts (Metema, West
Assessment of malaria endemicity at different altitudes and transmission intensities, in the era of dwindling vector densities in the highlands, will provide valuable information for malaria control and surveillance. Measurement of serum anti-malarial antibodies is a useful marker of malaria exposure that indicates long-term transmission potential. We studied the serologic evidence of malaria endemicity at two highland sites along a transmission intensity cline. An improved understanding of the micro-geographic variation in malaria exposure in the highland ecosystems will be relevant in planning effective malaria control.Total IgG levels to Plasmodium falciparum MSP-119 were measured in an age-stratified cohort (< 5, 5-14 and ? 15 years) in 795 participants from an uphill and valley bottom residents during low and high malaria transmission seasons. Antibody prevalence and level was compared between different localities. Regression analysis was performed to examine the association between ...

AU - Kanu, Ijeoma. AU - Merrick, Joav. PY - 2006/12/15. Y1 - 2006/12/15. N2 - The endemicity of malaria in tropical areas of the world persists, especially in countries south of Saharan Africa. The efforts and concerns invested by the World Health Organization and other health agencies to eradicate malaria are commendable. However, in spite of all these efforts, the loss in economic and human resources continues. In a previous report, the long-term health effects of insecticide-impregnated bednet (IIBN) use were highlighted with the expectation of attracting serious thoughts and further research on the issue. This present paper is an update on that expectation. Results from a comprehensive literature search show that not much work has been done on the effects of long-term exposure to IIBNs in combating ...
World Malaria Day 2017 Statement from Dr. Kesetebirhan Admasu Chief Executive Officer, Roll Back Malaria Partnership. We can be the generation to end malaria for good. April 25, 2017 - (Geneva, Switzerland). On World Malaria Day the global community unites to reflect on our progress and the challenges that lie ahead. Since 2000 we have made great strides in curbing the malaria epidemic. Thanks to the mobilization of resources and political will, malaria control and elimination efforts have resulted in nearly 7 million lives saved, hundreds of millions of infections averted and over US$2 trillion added to the economies of endemic countries. The Roll Back Malaria Partnership, recently revitalized and reinvigorated with new leadership and a new strategic approach has been central to this achievement. It remains pivotal in coordinating and convening partners worldwide to ensure sufficient and accessible resources for countries for malaria control and elimination efforts, and to providing cohesive ...
Background: Insecticide-treated mosquito nets (ITNs) have been shown to be very effective against malaria and are now a key tool of the global Roll Back Malaria initiative. There remain, however, concerns regarding possible higher mortality in children protected during early infancy due to interference with immunity development. Moreover, the long-term effects on malaria prevalence and morbidity are not well described. Methods: Between 2000 and 2002, a birth cohort was enrolled in 41 villages of a malaria holoendemic area in north-western Burkina Faso. All neonates (n=3387) were individually randomised to ITN protection from birth (group A) versus ITN protection from age 6 months (group B). Primary outcome was all-cause mortality. In 2009, a survey took place in 6 sentinel study villages, and in 2010, a census was conducted in all study villages.. Results: After a mean follow-up time of 7.3 years, 443/3387 (13.1%) children had migrated out of the area and 436/3230 (13%) had died, mostly at home. ...
Background. Conflicting reports exist regarding the impact of human immunodeficiency virus (HIV) infection on the risk of severe malaria. We aimed to assess the effect of HIV infection status, advancing immunosuppression, and antimalarial immunity on the severity of malaria.. Methods. A prospective cohort study was conducted. Consecutive hospitalized adult patients with falciparum malaria were tested for HIV antibodies and to determine CD4+ T cell count. Immunity to malaria was assessed by obtaining a history of childhood residence in an area where malaria is endemic. Patients were assessed for features of severe malaria.. Results. Three hundred thirty-six patients were enrolled in the study, of whom 32 (10%) had severe malaria. The prevalence of HIV infection was 33%, and 111 patients (33%) were nonimmune to malaria. HIV-infected patients complained more frequently about respiratory and abdominal symptoms and less frequently about rigors and headache. Risk factors for severe malaria determined ...
Naturally acquired human infections with Plasmodium knowlesi are endemic to Southeast Asia. To determine the prevalence of P. knowlesi malaria in malaria-endemic areas of Thailand, we analyzed genetic characteristics of P. knowlesi circulating among naturally infected macaques and humans. This study in 2008-2009 and retrospective analysis of malaria species in human blood samples obtained in 1996 from 1 of these areas showed that P. knowlesi accounted for 0.67% and 0.48% of human malaria cases, respectively, indicating that this simian parasite is not a newly emergent human pathogen in Thailand. Sequence analysis of the complete merozoite surface protein 1 gene of P. knowlesi from 10 human and 5 macaque blood samples showed considerable genetic diversity among isolates. The sequence from 1 patient was identical with that from a pig-tailed macaque living in the same locality, suggesting cross-transmission of P. knowlesi from naturally infected macaques to humans.
The Public Health Agency (PHA) is using World Malaria Day (25 April 2012) to warn travellers to take precautions on how to avoid this serious, sometimes fatal disease spread by the bite of infected mosquitoes in tropical countries. The number of malaria infections recorded among UK residents has increased by almost 30% in the last two years.. Malaria is common in many tropical countries, including large areas of Africa, Asia, Central and South America, Haiti and the Dominican Republic, parts of the Middle and Far East and some Pacific Ocean Islands.. Dr Michael Devine, Consultant in Health Protection, PHA, said: Although malaria is potentially deadly, it is almost completely preventable. There are two main ways of avoiding malaria and it is important to follow both of them. These are, taking malaria prevention tablets and avoiding mosquito bites.. Malaria prevention tablets. There are many different malaria prevention tablets and it is very important to take the right ones for the area that ...
A decade ago, Malaysia became a founding member of the Asia Pacific Malaria Elimination Network in an attempt to curb the high case rate of infection across Southeast Asia. The networks efforts - including widespread mosquito net distribution and increased funding for malaria research - helped see malaria rates fall in the region by 59% between 2010 to 2017. Read More: New Asia-Pacific Partnership Aims to Stop Fake Medicines Taking the Region Hostage. While Malaysias human malaria cases are essentially eliminated, health officials are concerned about an resurgence of the monkey malaria parasite. The rare form of malaria, known as Plasmodium knowlesi, infects the macaque monkey species and was long incorrectly thought not to affect humans.. According to the World Health Organization, Malaysia has the highest rates of Plasmodium knowlesi in the world. Since 2008, over 15,000 cases of monkey-linked malaria in humans have been reported in the country.. Read More: This New Malaria-Fighting Drug Is ...
Abstract. Background: Malaria accounts for the largest portion of healthcare demand in Angola. A pillar of malaria control in Angola is the appropriate management of malaria illness, including testing of suspect cases with rapid diagnostic tests (RDTs) and treatment of confrmed cases with artemisinin-based combination therapy (ACT). Periodic systematic evaluations of malaria case management are recommended to measure health facility readiness and adherence to national case management guidelines.. Methods: Cross-sectional health facility surveys were performed in low-transmission Huambo and high-transmission Uíge Provinces in early 2016. In each province, 45 health facilities were randomly selected from among all public health facilities stratified by level of care. Survey teams performed inventories of malaria commodities and conducted exit interviews and re-examinations, including RDT testing, of a random selection of all patients completing outpatient consultations. Key health facility ...
Dengue and malaria are two common, mosquito-borne infections, which may lead to mortality if not managed properly. Concurrent infections of dengue and malaria are rare due to the different habitats of its vectors and activities of different carrier mosquitoes. The first case reported was in 2005. Since then, several concurrent infections have been reported between the dengue virus (DENV) and the malaria protozoans, Plasmodium falciparum and Plasmodium vivax. Symptoms of each infection may be masked by a simultaneous second infection, resulting in late treatment and severe complications. Plasmodium knowlesi is also a common cause of malaria in Malaysia with one of the highest rates of mortality. This report is one of the earliest in literature of concomitant infection between DENV and P. knowlesi in which a delay in diagnosis had placed a patient in a life-threatening situation. A 59-year old man staying near the Belum-Temengor rainforest at the Malaysia-Thailand border was admitted with fever ...
Malaria is the most important parasitic disease of man. It infects approximately 5% of the worlds population and kills somewhere between one and two million people each year. Of the four species of malaria parasites that infect humans, only Plasmodium falciparum is lethal. Cerebral involvement causing coma in severe falciparum malaria is a characteristic but ominous development carrying a 15-20% treated case fatality. Untreated it is considered uniformly fatal. Cerebral malaria is widely quoted as being the most common cause of coma in tropical areas of the world.. WHO GETS CEREBRAL MALARIA? In some parts of the tropics malaria is acquired as many as two or three times every day and thus everyone in the community has malaria all the time. At the other end of the spectrum, there are many areas where the chances of acquiring malaria are relatively low. For example, along the western border of Thailand,. ...
Malaria prophylaxis is the preventive treatment of malaria. Several malaria vaccines are under development. Risk management Bite prevention-clothes that cover as much skin as possible, insect repellent, insecticide-impregnated bed nets and indoor residual spraying Chemoprophylaxis Rapid diagnosis and treatment Recent improvements in malaria prevention strategies have further enhanced its effectiveness in combating areas highly infected with the malaria parasite. Additional bite prevention measures include mosquito and insect repellents that can be directly applied to skin. This form of mosquito repellent is slowly replacing indoor residual spraying, which is considered to have high levels of toxicity by WHO (World Health Organization). Further additions to preventive care are sanctions on blood transfusions. Once the malaria parasite enters the erythorocytic stage, it can adversely affect blood cells, making it possible to contract the parasite through infected blood. Chloroquine may be used ...

Forest malaria is a complex but common phenomenon occurring in southeast Asia. We studied its epidemiology through a prospective community-based study in central Vietnam. A total of 585 individuals were followed for two years by active case detection and biannual cross-sectional surveys. The prevalence of antibodies to Plasmodium falciparum was constantly about 20% across surveys and the incidence rate of clinical episodes of P. falciparum malaria was 0.11/person-year. Multivariate analysis showed that regular forest activity was the main risk factor for clinical malaria and malaria infections. Untreated bed nets had a significant protective effect (60%), except for people regularly sleeping in the forest. The population-attributable fraction for regular forest activity was estimated to be 53%. Our results confirm the major role played by forest activity on the malaria burden in this area and provide the basis for targeting control activities to forest workers. New interventions based on insecticide
The relationships between human population movement (HPM) and health are a concern at the global level. In the case of malaria, those links are crucial in relation to the spread of drug-resistant parasites and to the elimination of malaria in the Greater Mekong sub-Region (GMS) and beyond. The mobile and migrant populations (MMP) who are involved in forest-related activities are both at high risk of being infected with malaria and at risk of receiving late and sub-standard treatment due to poor access to health services. In Cambodia, in 2012, the National Malaria Control Programme (NMCP) identified, as a key objective, the development of a specific strategy for MMPs in order to address these challenges. A population movement framework (PMF) for malaria was developed and operationalized in order to contribute to this strategy.. Read the full piece from Malaria Journal here.. ...

The efficacy of malaria control and elimination on islands may depend on the intensity of new parasite inflow. On the Comoros archipelago, where falciparum malaria remains a major public health problem because of spread of drug resistance and insufficient malaria control, recent interventions for malaria elimination were planned on Moheli, 1 of 4 islands in the Comoros archipelago. To assess the relevance of such a local strategy, we performed a population genetics analysis by using multilocus microsatellite and resistance genotyping of Plasmodium falciparum sampled from each island of the archipelago. We found a contrasted population genetic structure explained by geographic isolation, human migration, malaria transmission, and drug selective pressure. Our findings suggest that malaria elimination interventions should be implemented simultaneously on the entire archipelago rather than restricted to 1 island and demonstrate the necessity for specific chemoresistance surveillance on each of the 4
Female and male mice deficient in IL-10 production by targeted disruption of the IL-10 gene were infected with Plasmodium chabaudi chabaudi (AS) blood-stage parasites. Both male and female mutant mice exhibited more severe signs of disease than did +/+ or heterozygous control mice. Female defective mice also displayed an increased mortality; 56% of mice died within 20 days of infection. Mortality did not appear to be due to a fulminating parasitemia as death occurred at different levels of parasitemia in the individual mice. The acute infection was accompanied by an enhanced Th1 IFN-gamma response. This response was retained in the chronic phase of infection of both male and female mutant mice, whereas in controls the responding CD4+ T cells were predominantly Th2 cells secreting IL-4. The data suggest that IL-10 regulates the inflammatory response to the parasite and that in its absence the combined effects of malaria toxins and the sustained or enhanced IFN-gamma response lead to increased ...

Malaria is a mosquito-borne disease causing fever, chills and flu-like illness that can be fatal. Despite an increased focus on malaria, it still claims hundreds of thousands of lives each year, most of them children in Africa. Poor quality antimalarial drugs, which lead to drug resistance and inadequate treatment, are also a growing concern, posing an urgent threat to vulnerable populations.. Fogarty has supported a wide range of efforts to combat malaria, including the Multilateral Initiative on Malaria, an international effort to identify and address malaria research priorities. Ecology and Evolution of Infectious Diseases, a joint NIH - National Science Foundation (NSF) initiative, funds malaria-related projects in Kenya, Papua New Guinea, Belize and more. Through the Global Infectious Disease program, Fogarty has supported research training efforts that advance scientific discoveries, while developing local malaria research capacity in places where its needed most.. Fogartys epidemiology ...
The emergence and spread of multidrug resistant (MDR) malaria caused by |i|Plasmodium falciparum|/i| or |i|Plasmodium vivax|/i| have become increasingly important in the Greater Mekong Subregion (GMS). MDR malaria is the heritable and hypermutable property of human malarial parasite populations that can decrease |i|in vitro|/i| and |i|in vivo|/i| susceptibility to proven antimalarial drugs as they exhibit dose-dependent drug resistance and delayed parasite clearance time in treated patients. MDR malaria risk situations reflect consequences of the national policy and strategy as this influences the ongoing national-level or subnational-level implementation of malaria control strategies in endemic GMS countries. Based on our experience along with current literature review, the design of ecotope-based entomological surveillance (EES) and molecular xenomonitoring of MDR falciparum and vivax malaria parasites in |i|Anopheles|/i| vectors is proposed to monitor infection pockets in transmission control areas
Abstract. Ivermectin mass drug administration (MDA) to humans is used to control onchocerciasis and lymphatic filariasis. Recent field studies have shown an added killing effect of ivermectin MDA against malaria vectors. We report that ivermectin MDA reduced the proportion of Plasmodium falciparum infectious Anopheles gambiae sensu stricto (s.s.) in treated villages in southeastern Senegal. Ivermectin MDA is a different delivery method and has a different mode of action from current malaria control agents. It could be a powerful and synergistic new tool to reduce malaria transmission in regions with epidemic or seasonal malaria transmission, and the prevalence and intensity of neglected tropical diseases.

Haptoglobin (Hp) scavenges free hemoglobin following malaria-induced hemolysis. Few studies have investigated the relationship between the common Hp variants and the risk of severe malaria, and their results are inconclusive. We conducted a case-control study of 996 children with severe Plasmodium falciparum malaria and 1220 community controls and genotyped for Hp, hemoglobin (Hb) S heterozygotes, and α(+)thalassemia. Hb S heterozygotes and α(+)thalassemia homozygotes were protected from severe malaria (odds ratio [OR], 0.12; 95% confidence interval [CI], 0.07-0.18 and OR, 0.69; 95% CI, 0.53-0.91, respectively). The risk of severe malaria also varied by Hp genotype: Hp2-1 was associated with the greatest protection against severe malaria and Hp2-2 with the greatest risk. Meta-analysis of the current and published studies suggests that Hp2-2 is associated with increased risk of severe malaria compared with Hp2-1. We found a significant interaction between Hp genotype and α(+)thalassemia in predicting
An unmatched case-control study was conducted. Severe malaria cases and mild malaria controls were children (aged 1 month - 15 years) of Mossi ethnicity, admitted to hospital with signs of severe and uncomplicated malaria, respectively. The children were recruited from patients admitted to the paediatric ward of three hospitals in Ouagadougou (Centre Hospitalier Universitaire Yalgado Ouédraogo, Centre Médical Paul VI and Centre Médical Saint Camille) during the high malaria transmission seasons of 1993-94.. The criteria for inclusion followed the definitions stated by the World Health Organization (WHO). Severe malaria was defined by the presence of P. falciparum in the thick blood film associated with at least one of the following conditions: prostration (incapacity of child to sit without help in absence of coma), unrousable coma (Blantyre coma score ≤ 2), repeated generalised convulsions (more than two episodes in the preceding 24 hr), severe anaemia (haemoglobin ,5 g/dl), hypoglycemia ...
BACKGROUND:Treatment for severe malaria must be prompt with effective parenteral antimalarial drugs for at least 24 h to achieve fast parasite clearance, and when the patient can tolerate oral therapy, treatment should be completed with effective artemisinin based combination therapy (ACT) for complete parasite clearance and to prevent recrudescence. We evaluated piperaquine concentration and malaria treatment outcomes among Ugandan children treated for severe malaria with intravenous artesunate (AS) or quinine (QN) plus dihydroartemisinin-piperaquine (DP), in Tororo District Hospital in Eastern Uganda. METHODS:Capillary blood piperaquine concentration data were obtained from a randomized clinical trial whose objective was to evaluate parasite clearance, 42-day parasitological treatment outcomes and safety, following treatment of severe malaria with intravenous AS or QN, plus artemether-lumefantrine or DP among children in Tororo District Hospital, in Eastern Uganda. RESULTS:Piperaquine concentration
Southern Africa is currently experiencing the annual malaria season and as expected there has been an increase in transmission due to the rise in ambient temperature, rainfall and humidity as compared to the same period last year.. With the approach of the holiday season in April, it is important for travellers visiting any of the malaria areas within Southern Africa and elsewhere to take appropriate precautions and maintain a high index of suspicion for symptoms of malaria on their return.. Where is malaria found?. The areas of transmission of malaria in South Africa are the north -eastern parts of Limpopo (along the borders with Mozambique and Zimbabwe), the lowveld areas of Mpumalanga (including the Kruger National Park but excluding Mbombela and immediate surrounds) and the far northern parts of Kwa-Zulu Natal (see map). While the Kruger National Park does fall in the malaria risk area, the transmission risk would be considered low to moderate, depending on the specific camps visited for ...
In Sub Saharan Africa malaria remains one of the major health problems and its control represents an important public health measure. Integrated malaria control comprises the use of impregnated mosquito nets and indoor residual spraying. The use of drugs to treat patients can create additional pressure on the equation of malaria transmission. Vector control may target the adult mosquitoes or their aquatic larval stages. Biological larvicides such as Bacillus thuringiensis israelensis (Bti) represent a promising approach to support malaria control programs by creating additional pressure on the equation of malaria transmission. In this study we examined the efficacy of a water-dispersible granule formulation (WDG) of the biological larvicide Bti (VectoBac®) against wild Anopheles spp. larvae. Different concentrations of the larvicide were tested in standardized plastic tubs in the field against untreated controls. In weekly intervals tubs were treated with fixed concentrations of larvicide and the
Malaria infection is a major problem in many countries. The use of the Insecticide-Treated BedNets (ITNs) has been shown to significantly reduce the number of malaria infections; however, the effectiveness is often jeopardized by improper handling or human behavior such as inconsistent usage. In this paper, we present a game-theoretical model for ITN usage in communities with malaria infections. We show that it is in the individuals self interest to use the ITNs as long as the malaria is present in the community. Such an optimal ITN usage will significantly decrease the malaria prevalence and under some conditions may even lead to complete eradication of the disease.. ...
