Infections caused by arthropod-borne viruses, general or unspecified.
Arthropod-borne viruses. A non-taxonomic designation for viruses that can replicate in both vertebrate hosts and arthropod vectors. Included are some members of the following families: ARENAVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; TOGAVIRIDAE; and FLAVIVIRIDAE. (From Dictionary of Microbiology and Molecular Biology, 2nd ed)
Encephalitis caused by neurotropic viruses that are transmitted via the bite of TICKS. In Europe, the diseases are caused by ENCEPHALITIS VIRUSES, TICK-BORNE, which give rise to Russian spring-summer encephalitis, central European encephalitis, louping ill encephalitis, and related disorders. Powassan encephalitis occurs in North America and Russia and is caused by the Powassan virus. ASEPTIC MENINGITIS and rarely encephalitis may complicate COLORADO TICK FEVER which is endemic to mountainous regions of the western United States. (From Joynt, Clinical Neurology, 1996, Ch26, pp14-5)
Infections of the brain caused by arthropod-borne viruses (i.e., arboviruses) primarily from the families TOGAVIRIDAE; FLAVIVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; and RHABDOVIRIDAE. Life cycles of these viruses are characterized by ZOONOSES, with birds and lower mammals serving as intermediate hosts. The virus is transmitted to humans by the bite of mosquitoes (CULICIDAE) or TICKS. Clinical manifestations include fever, headache, alterations of mentation, focal neurologic deficits, and COMA. (From Clin Microbiol Rev 1994 Jan;7(1):89-116; Walton, Brain's Diseases of the Nervous System, 10th ed, p321)
A collection of single-stranded RNA viruses scattered across the Bunyaviridae, Flaviviridae, and Togaviridae families whose common property is the ability to induce encephalitic conditions in infected hosts.
A family of the order DIPTERA that comprises the mosquitoes. The larval stages are aquatic, and the adults can be recognized by the characteristic WINGS, ANIMAL venation, the scales along the wing veins, and the long proboscis. Many species are of particular medical importance.
A syndrome that is associated with microvascular diseases of the KIDNEY, such as RENAL CORTICAL NECROSIS. It is characterized by hemolytic anemia (ANEMIA, HEMOLYTIC); THROMBOCYTOPENIA; and ACUTE RENAL FAILURE.
A disease caused by potent protein NEUROTOXINS produced by CLOSTRIDIUM BOTULINUM which interfere with the presynaptic release of ACETYLCHOLINE at the NEUROMUSCULAR JUNCTION. Clinical features include abdominal pain, vomiting, acute PARALYSIS (including respiratory paralysis), blurred vision, and DIPLOPIA. Botulism may be classified into several subtypes (e.g., food-borne, infant, wound, and others). (From Adams et al., Principles of Neurology, 6th ed, p1208)
Intestinal infection with organisms of the genus CRYPTOSPORIDIUM. It occurs in both animals and humans. Symptoms include severe DIARRHEA.
A toxin produced by certain pathogenic strains of ESCHERICHIA COLI such as ESCHERICHIA COLI O157. It is closely related to SHIGA TOXIN produced by SHIGELLA DYSENTERIAE.
Programs of surveillance designed to prevent the transmission of disease by any means from person to person or from animal to man.
Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.

Serum dilution neutralization test for California group virus identification and serology. (1/166)

The serum dilution neutralization test was evaluated for serological diagnosis of California group arbovirus infections and identification of virus isolates. The technical advantages and the degree of subtype specificity of the serum dilution neutralization test over the hemagglutination inhibition test and the complement fixation test were demonstrated with paired specimens from human cases, single human survey sera, and sentinel rabbit sera. Twenty-one virus isolates from various geographical areas of the United States were also used to evaluate the efficacy of the serum dilution neutralization test for specific virus identification.  (+info)

Mechanisms of arthropod transmission of plant and animal viruses. (2/166)

A majority of the plant-infecting viruses and many of the animal-infecting viruses are dependent upon arthropod vectors for transmission between hosts and/or as alternative hosts. The viruses have evolved specific associations with their vectors, and we are beginning to understand the underlying mechanisms that regulate the virus transmission process. A majority of plant viruses are carried on the cuticle lining of a vector's mouthparts or foregut. This initially appeared to be simple mechanical contamination, but it is now known to be a biologically complex interaction between specific virus proteins and as yet unidentified vector cuticle-associated compounds. Numerous other plant viruses and the majority of animal viruses are carried within the body of the vector. These viruses have evolved specific mechanisms to enable them to be transported through multiple tissues and to evade vector defenses. In response, vector species have evolved so that not all individuals within a species are susceptible to virus infection or can serve as a competent vector. Not only are the virus components of the transmission process being identified, but also the genetic and physiological components of the vectors which determine their ability to be used successfully by the virus are being elucidated. The mechanisms of arthropod-virus associations are many and complex, but common themes are beginning to emerge which may allow the development of novel strategies to ultimately control epidemics caused by arthropod-borne viruses.  (+info)

El Nino and arboviral disease prediction. (3/166)

Recent El Nino events have stimulated interest in the development of modeling techniques to forecast extremes of climate and related health events. Previous studies have documented associations between specific climate variables (particularly temperature and rainfall) and outbreaks of arboviral disease. In some countries, such diseases are sensitive to El Nino. Here we describe a climate-based model for the prediction of Ross River virus epidemics in Australia. From a literature search and data on case notifications, we determined in which years there were epidemics of Ross River virus in southern Australia between 1928 and 1998. Predictor variables were monthly Southern Oscillation index values for the year of an epidemic or lagged by 1 year. We found that in southeastern states, epidemic years were well predicted by monthly Southern Oscillation index values in January and September in the previous year. The model forecasts that there is a high probability of epidemic Ross River virus in the southern states of Australia in 1999. We conclude that epidemics of arboviral disease can, at least in principle, be predicted on the basis of climate relationships.  (+info)

Langerhans cells migrate to local lymph nodes following cutaneous infection with an arbovirus. (4/166)

Whereas there has been recent interest in interactions between dendritic cells and pathogenic viruses, the role of dendritic cells in the initiation of protective immunity to such organisms has not been elucidated. The aim of this study was to examine whether a resident dendritic cell population in the skin, Langerhans cells, respond to cutaneous viral infections which are effectively cleared by the immune system. We therefore characterized the ability of Langerhans cells to migrate to local draining lymph nodes following infection with the arthropod-borne viruses, West Nile virus or Semliki Forest virus. The data show that major histocompatibility complex class II+/NLDC145+/E-cadherin+ Langerhans cell numbers are increased in the draining lymph nodes of infected mice and this increase is accompanied by a concomitant decrease in the Langerhans cell density in the epidermis. Langerhans cell migration is associated with an accumulation of leukocytes in the lymph node, which is one of the earliest events in the initiation of an immune response. Both the migratory response and the draining lymph node leukocyte accumulation were abrogated if ultraviolet-inactivated instead of live viruses were used, suggesting the activation and subsequent migration of Langerhans cells requires a live, replicating antigen. Our findings are likely to have wider implications for the development of epidermally delivered vaccines and suggest that mobilization of dendritic cells may be involved in the development of immune responses to arthropod-borne viruses.  (+info)

H-2-linked control of cytotoxic T-cell responsiveness to alphavirus infection. Presence of H-2Dk during differentiation and stimulation converts stem cells of low responder genotype to T cells of responder phenotype. (5/166)

Secondary Tc cells generated against Sindbis virus (SIN) are restricted to Dk. All other H-2K or D regions tested show low specific responsiveness. F1 hybrids between low and high responders show dominance of responsiveness but lack complementation. When BALB/c (KdIdDd) low responder fetal liver stem cells were allowed to mature in irradiated high responder recipients C3H.OH (KdIdDk) a response to Dk plus SIN could be generated with Tc cells of BALB/c origin. This result, together with the failure of complementation in the F1 hybrids, implies that the lesion of low responsiveness is in the inability of viral antigen to stimulate a Tc-cell response in association with any self H-2K or H-2D molecule (of those tested) other than H-2Dk. Hypotheses compatible with these data are discussed.  (+info)

Standardization of immunoglobulin M capture enzyme-linked immunosorbent assays for routine diagnosis of arboviral infections. (6/166)

Immunoglobulin M antibody-capture enzyme-linked immunosorbent assay (MAC-ELISA) is a rapid and versatile diagnostic method that readily permits the combination of multiple assays. Test consolidation is especially important for arthropod-borne viruses (arboviruses) which belong to at least three virus families: the Togaviridae, Flaviviridae, and Bunyaviridae. Using prototype viruses from each of these families and a panel of well-characterized human sera, we have evaluated and standardized a combined MAC-ELISA capable of identifying virus infections caused by members of each virus family. Furthermore, by grouping antigens geographically and utilizing known serological cross-reactivities, we have reduced the number of antigens necessary for testing, while maintaining adequate detection sensitivity. We have determined that a 1:400 serum dilution is most appropriate for screening antiviral antibody, using a positive-to-negative ratio of >/=2.0 as a positive cutoff value. With a blind-coded human serum panel, this combined MAC-ELISA was shown to have test sensitivity and specificity that correlated well with those of other serological techniques.  (+info)

Detection of anti-arboviral immunoglobulin G by using a monoclonal antibody-based capture enzyme-linked immunosorbent assay. (7/166)

Monoclonal antibody (MAb)-based capture enzyme-linked immunosorbent assays (ELISAs) for the detection of anti-arboviral immunoglobulin G (IgG ELISAs) were developed for a comprehensive array of medically important arboviruses from the Alphavirus, Flavivirus, and Bunyavirus genera. Tests were optimized and standardized so that maximum homology could be maintained among working parameters for the different viral agents, enabling a wide range of viruses to be easily tested for at one time. MAbs were screened for suitability as capture vehicles for antigens from the three genera. The final test configuration utilized group-reactive MAbs eastern equine encephalitis virus 1A4B-6, dengue 2 virus 4G2, and La Crosse encephalitis virus 10G5.4 to capture the specific inactivated viral antigens. Serum IgG was detected by using alkaline phosphatase-conjugated anti-human IgG (Fc portion). A dilution of 1:400 was chosen as the universal screening serum dilution, with endpoint titrations of serum samples testing positive eliminating occasional false-positive results. IgG ELISA results correlated with those of the standard plaque-reduction neutralization assays. As expected, some test cross-reactivity was encountered within the individual genera, and tests were interpreted within the context of these reactions. The tests were standardized for laboratory diagnosis of arboviral infections, with the intent that they be used in tandem with the corresponding IgM antibody-capture ELISAs.  (+info)

Molecular strategies for interrupting arthropod-borne virus transmission by mosquitoes. (8/166)

Arthropod-borne virus (arbovirus) infections cause a number of emerging and resurgent human and veterinary infectious diseases. Traditional means of controlling arbovirus diseases include vaccination of susceptible vertebrates and mosquito control, but in many cases these have been unavailable or ineffective, and so novel strategies for disease control are needed. One possibility is genetic manipulation of mosquito vectors to render them unable to transmit arboviruses. This review describes recent work to test the concept of pathogen-derived resistance in arthropods by expression of viral genes in mosquito cell cultures and mosquitoes. Sense and antisense genome sequences from La Crosse virus (LAC) (a member of the Bunyaviridae) and dengue viruses serotypes 1 to 4 (DEN-1 to DEN-4) (members of the Flaviviridae) were expressed in mosquito cells from double-subgenomic and replicon vectors based on Sindbis virus (a member of the Togaviridae). The cells were then challenged with homologous or related viruses. For LAC, expression of antisense sequences from the small (S) genome segment, particularly full-length antisense S RNA, effectively interfered with replication of challenge virus, whereas expression of either antisense or sense RNA from the medium (M) segment was completely ineffective in LAC inhibition. Expression of sense and antisense RNA derived from certain regions of the DEN genome also blocked homologous virus replication more effectively than did RNA from other regions. Other parameters of RNA-mediated interference have been defined, such as the time when replication is blocked and the minimum size of effector RNA. The mechanism of RNA inhibition has not been determined, although it resembles double-stranded RNA interference in other nonvertebrate systems. Prospects for application of molecular strategies to control arbovirus diseases are briefly reviewed.  (+info)

Arthropod-borne viruses - arboviruses - are a significant threat to public health. Whilst there is considerable knowledge about arbovirus interactions with vertebrate immunity, relatively little is known about how vectors such as mosquitoes control arbovirus infections. In this review, we discuss novel findings in the field of mosquito antiviral responses to arboviruses, in particular RNA interference, the up-and-coming field of general immune-signalling pathways, and cell death/apoptosis.
Houston and Harris County for instance, are home to two major mosquito species - Aedes aegypti and Aedes albopictus - that can transmit several arboviruses such as dengue, yellow fever, and chikungunya virus. Research led by Dr. Kristy O. Murray provided strong evidence that dengue emerged in Houston between 2003 and 2005. Our region is also home to the Culex mosquitoes that transmit West Nile virus infection. These arbovirus infections have important health and economic consequences for the region.

Arbovirus is a term used to refer to any viruses that is transmitted by arthropod vectors. The word arbovirus is an acronym (ARthropod-BOrne virus). The word tibovirus (TIck-BOrne virus) is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals, including humans, and plants. In humans, symptoms of arbovirus infection generally occur 3-15 days after exposure to the virus and last 3 or 4 days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and hemorrhagic fever may also occur. Arboviruses were not known to exist until the rise of modern medicine, with the germ theory and an understanding that viruses were distinct from other microorganisms. The connection between arthropods and disease was not postulated until 1881 when Cuban doctor and scientist Carlos Finlay proposed that yellow fever may be transmitted by mosquitoes instead of human contact, a reality ...
Summary The influence of lowered body temperature and depressed metabolic rate of the cold-exposed bat on experimental arbovirus infection has been studied using three species of insectivorous bats, Tadarida b. mexicana, Myotis l. lucifugus, and Eptesicus f. fuscus. One strain of St. Louis encephalitis (SLE) virus and two strains of Japanese B encephalitis (JBE) virus were employed. Although the effects of low temperature on experimental arbovirus infection in bats varied with the bat species used and the relationship between inoculation of virus and the initiation of cold-exposure, the results obtained indicated that these animals would be ideal hosts for overwintering of arboviruses in nature. Generally, infection in bats was suppressed by low temperature but sustained by the animals for several months as evidenced by (1) the demonstration of low levels of virus in the blood and brown adipose tissue of the hibernating bat, and (2) the activation of viral multiplication upon transfer to 24°C producing

The rapid succession of the pandemic of arbovirus diseases, such as dengue, West Nile fever, chikungunya, and Zika fever, has intensified research on these and other arbovirus diseases worldwide. Investigating the unique mode of vector-borne transmission requires a clear understanding of the roles of vertebrates. One major obstacle to this understanding is the ambiguity of the arbovirus definition originally established by the World Health Organization. The paucity of pertinent information on arbovirus transmission at the time contributed to the notion that vertebrates played the role of reservoir in the arbovirus transmission cycle. Because this notion is a salient feature of the arbovirus definition, it is important to reexamine its validity. This review addresses controversial issues concerning vertebrate reservoirs and their role in arbovirus persistence in nature, examines the genesis of the problem from a historical perspective, discusses various unresolved issues from multiple points of view,
Arboviruses (arthropod-borne virus) cause viral infections that are spread by mosquitoes and other blood-sucking insects, such as ticks. Arbovirus testing can help diagnose the cause of meningitis or encephalitis and distinguish an arbovirus infection from other conditions causing similar symptoms.

BACKGROUND: Epidemic arbovirus transmission occurs among humans by mosquito bites and the sylvatic transmission cycles involving non-human primates (NHPs) still exists. However, limited data are available on the extent in NHPs infections and their role. In this study, we have developed and validated a high-throughput serological screening tool to study the circulation of multiple arboviruses that represent a significant threat to human health, in NHPs in Central Africa.METHODOLOGY/PRINCIPAL FINDINGS: Recombinant proteins NS1, envelope domain-3 (DIII) for the dengue (DENV), yellow fever (YFV), usutu (USUV), west nile (WNV) and zika (ZIKV) and envelope 2 for the chikungunya (CHIKV) and onyong-nyong (ONNV) were coupled to Luminex beads to detect IgG directed against these viruses. Evaluation of test performance was made using 161 human sera of known arboviral status (66 negative and 95 positive). The sensitivity and specificity of each antigen were determined by statistical methods and ROC curves ...
Background , Models of arbovirus transmission are useful in estimating the burden of Dengue, forecasting areas of risk for the emergence of Dengue, Chikungunya and Zika in non-endemic areas, and in assessing the potential of control interventions. The utility of these models relies on their grounding in empirical data at multiple scales describing the disease transmission process. The aims are to (i) model the dynamics of viruses in their invertebrate and vertebrate hosts as well as the movement of these hosts viz ...
The arbovirus transmission project in ABADRU and KSU will aim to understand the biological processes associated with establishment of infection in vectors, transmission of virus, establishment of mammalian infection as well as disease pathogenesis and immunity that could impact the domestic feral and commercial swine.

Summary Hemagglutination-inhibiting antibody responses with selected Group B arthropod-borne virus antigens were studied following administration of living attenuated 17D strain yellow fever vaccine to human subjects who had (a) no previous Group B arbovirus experience, (b) only 17D strain vaccine previously, (c) previous inapparent natural Japanese encephalitis virus infection and (d) complex Group B arbovirus experience previously. The results indicate the following: 1. Previous homologous or heterologous immunological experience did not suppress the yellow fever HI response to the living vaccine. On the contrary, the response was sometimes enhanced. 2. Heterologous HI responses depended upon the nature of the previous Group B arbovirus experience. (a) Subjects with no prevaccination Group B arbovirus experience developed a limited array of low-titered heterologous antibodies. (b) Subjects previously vaccinated with the 17D strain but with no other Group B arbovirus experience exhibited limited
Arthropod-borne viruses (arboviruses) are important human pathogens for which there are no specific antiviral medicines. The abundance of genetically distinct arbovirus species, coupled with the unpredictable nature of their outbreaks, has made the development of virus-specific treatments challenging. Instead, we have defined and targeted a key aspect of the host innate immune response to virus at the arthropod bite that is common to all arbovirus infections, potentially circumventing the need for virus-specific therapies. Using mouse models and human skin explants, we identify innate immune responses by dermal macrophages in the skin as a key determinant of disease severity. Post-exposure treatment of the inoculation site by a topical TLR7 agonist suppressed both the local and subsequent systemic course of infection with a variety of arboviruses from the Alphavirus, Flavivirus, and Orthobunyavirus genera. Clinical outcome was improved in mice after infection with a model alphavirus. In the ...
Globally, arthropod-borne virus infections are increasingly common causes of severe febrile disease that can progress to long-term physical or cognitive impairment or result in early death. Because of the large populations at risk, it has been suggested that these outcomes represent a substantial health deficit not captured by current global disease burden assessments. We reviewed newly available data on disease incidence and outcomes to critically evaluate the disease burden (as measured by disability-adjusted life years, or DALYs) caused by yellow fever virus (YFV), Japanese encephalitis virus (JEV), chikungunya virus (CHIKV), and Rift Valley fever virus (RVFV). We searched available literature and official reports on these viruses combined with the terms outbreak(s), complication(s), disability, quality of life, DALY, and QALY, focusing on reports since 2000. We screened 210 published studies, with 38 selected for inclusion. Data on average incidence, duration, age at onset, mortality,
In nature, infected and uninfected arthropod vectors often feed together on an animal. In mimicking this scenario in the laboratory, uninfected vectors were found to acquire virus while cofeeding on the same host as infected vectors. However, the vertebrate host on which they fed did not develop detectable levels of virus in its blood. These observations were made with Thogoto virus, an influenza-like virus of medical and veterinary significance. Rhipicephalus appendiculatus ticks were used as the vector and guinea pigs as the vertebrate host. The results demonstrate that a vertebrate that is apparently refractory to infection by an arthropod-borne virus can still play an important role in the epidemiology of the virus, and they suggest a novel mode of arthropod-borne virus transmission.

Slave trading of Africans to the Americas, during the 16th to the 19th century was responsible for the first recorded emergence in the New World of two arthropod-borne viruses (arboviruses), yellow fever virus and dengue virus. Many other arboviruses have since emerged from their sylvatic reservoirs and dispersed globally due to evolving factors that include anthropological behaviour, commercial transportation and land-remediation. Here, we outline some characteristics of these highly divergent arboviruses, including the variety of life cycles they have developed and the mechanisms by which they have adapted to evolving changes in habitat and host availability. We cite recent examples of virus emergence that exemplify how arboviruses have exploited the consequences of the modern human lifestyle. Using our current understanding of these viruses, we also attempt to demonstrate some of the limitations encountered in developing control strategies to reduce the impact of future emerging arbovirus ...
Background Dengue offers emerged as the most significant of arboviral diseases in the 21st century. of this cloned dengue protease we randomly screened ~1000 small molecules from an in-house library to identify potential dengue protease inhibitors. Results A benzimidazole derivative, named MB21, was found to be the most potent in inhibiting the cloned protease (IC50?=?5.95?M). docking analysis indicated that MB21 binds to the protease in the vicinity of the active site.

Arthropod-borne viruses (arboviruses) are important causes of human disease nearly worldwide. All arboviruses circulate among wild animals, and many cause disease after spillover transmission to humans and agriculturally important domestic animals that are incidental or dead-end hosts. Viruses such as dengue (DENV) and chikungunya (CHIKV) that have lost the requirement for enzootic amplification now produce extensive epidemics in tropical urban centers. Many arboviruses recently have increased in importance as human and veterinary pathogens using a variety of mechanisms. Beginning in 1999, West Nile virus (WNV) underwent a dramatic geographic expansion into the Americas. High amplification associated with avian virulence coupled with adaptation for replication at higher temperatures in mosquito vectors, has caused the largest epidemic of arboviral encephalitis ever reported in the Americas. Japanese encephalitis virus (JEV), the most frequent arboviral cause of encephalitis worldwide,
Zika virus is a mosquito-borne flavivirus that was first identified in Uganda in 1947 in monkeys. The first large outbreak of disease caused by Zika infection was reported from the Island of Yap (Federated States of Micronesia) in 2007. Sexual transmission of Zika virus has been confirmed with other modes of transmission being investigated. The incubation period of Zika virus disease is not well defined but is likely to be a few days - similar to other arbovirus infections such as dengue. A diagnosis of Zika virus infection can only be confirmed through laboratory tests on blood or other body fluids, such as urine, saliva or semen.. In 2015, an association between Zika virus infection and Guillain-Barré syndrome and microcephaly was reported. Now, a comprehensive review, confirms that the Zika virus is a cause of microcephaly and Guillain-Barré syndrome. Some evidence exists that other neurological disorders are linked with Zika infection. ...
As public health agencies struggle to track and contain emerging arbovirus threats, timely and efficient surveillance is more critical than ever.

Survey for antibodies against arthropod-borne viruses in man and animals in Italy. 3. Serologic status of human beings and animals in a southern Italian region
Peter Hotez and Serap Aksoy, co-Editors in Chief of PLOS Neglected Tropical Diaseases, contemplate the recent rises in various vector-borne NTDs around the world. In 2013 both chikungunya and Zika virus infection are believed to have first emerged in the Western Hemisphere where both viruses now affect much of the population of Latin America and the Caribbean region and also threaten the United States. Chikungunya made its first appearance on the Caribbean island nation of Saint Martin at the end of 2013 and has since spread throughout much of the Americas, including the first locally acquired case in Texas reported this year. Similarly, molecular clock studies indicate that Zika probably first entered the Americas between May and December of 2013 before also spreading throughout Latin America and the Caribbean region, and there are fears that transmission of Zika might start by later this summer in the continental US.. While the rapid dissemination of these arbovirus infections in the Western ...
Arthropod-borne viruses, or arboviruses, are viruses that are transmitted through the bites of mosquitoes and ticks. There are numerous arboviruses throughout the world capable of causing human disease spanning different viral families and genera. Recently, dengue, chikungunya, and zika viruses have emerged as increasingly important arboviruses that can cause human disease, however no specific treatment or vaccine is available for them. In addition, ocular manifestations of these diseases have become more prevalent over the past few years. This review highlights the current understanding on the pathogenesis, systemic changes and ocular findings, emphasizing the retinal manifestations related to dengue, chikungunya, and zika viruses.
Arboviruses (or arthropod-borne viruses) are a heterogeneous group of viruses that share the same usual route of entry into humans: via the bite of an infected mosquito, tick, sandfly, or other arthropod.1,2 The life cycle of most arboviruses is characterized by the ability of the virus to replicate in both an arthropod vector and a vertebrate natural host (usually birds or small mammals) and by transmission between these two organisms at the time of the arthropods bite (eFig. 305.1). This cycle leads to establishment or maintenance of the virus in a given ecosystem. Humans or domestic animals are only incidental hosts for many species of arboviruses, as infection in such hosts (although capable of causing disease) is often a dead-end for the virus due to viremia being too low or too transient to contribute to maintenance of the cycle of transmission. Some viruses are specific to a single genus or species of insect, while others are transmissible by multiple vectors. In addition, some ...

We found this interesting information on the internet and thought you would like to be aware of the symptoms of Zika…especially since its so new here in the US.. Symptoms of Zika virus in most people are similar to other arboviruses such as Chikungunya (fever, headache, fatigue primarily). The recent epidemic in Brazil, however, has been distinctively marked by detection of the disease in fetal amniotic fluid and an elevated reporting of cases of microcephaly (small head size) in newborns.. Given the virus recent introduction to the Americas, some epidemiologists have expressed concern that resistance may be low, leading to increased transmission rates and severity of symptoms. In rare cases, Zika symptoms have been associated with Guillain-Barre syndrome, which causes the bodys immune system to attack its neurological system and can lead to paralysis..

We found this interesting information on the internet and thought you would like to be aware of the symptoms of Zika…especially since its so new here in the US.. Symptoms of Zika virus in most people are similar to other arboviruses such as Chikungunya (fever, headache, fatigue primarily). The recent epidemic in Brazil, however, has been distinctively marked by detection of the disease in fetal amniotic fluid and an elevated reporting of cases of microcephaly (small head size) in newborns.. Given the virus recent introduction to the Americas, some epidemiologists have expressed concern that resistance may be low, leading to increased transmission rates and severity of symptoms.

Key Public Risk Communication Messages for the Week of Sept 24, 2012:. 1. Day time and early evening temperatures are still warm enough for continued mosquito activity. Mosquito activity drops off when temperatures are below 60 but some mosquitoes will be active even down to 52 degrees.. 2. At this time of year, the mosquitoes that remain are older adults; as mosquitoes age, they are more likely to have picked up either EEE or WNV so a greater proportion of them are probably infected. Because of cooler temperatures, mosquito trapping is less effective and the increased infection rates are not always obvious based on mosquito testing results.. 3. Communities at high or critical risk for EEE are urged to consider rescheduling outdoor, evening events that occur between the hours of dusk and dawn. Communities at high or critical risk for WNV should consider outreach to residents over the age of 50 with information about peak mosquito activity hours.. ...
Mosquitoes are small, midge-like flies, which comprise the family Culicidae. Females of most species are ectoparasites, whose tube-like mouthparts (called a proboscis) pierce the hosts skin to consume blood. The word mosquito (formed by mosca and diminutive ito) is Spanish for little fly.[2] Thousands of species feed on the blood of various kinds of hosts, mainly vertebrates, including mammals, birds, reptiles, amphibians, and even some kinds of fish. Some mosquitoes also attack invertebrates, mainly arthropods. Though the loss of blood is seldom of any importance to the victim, the saliva of the mosquito often causes an irritating rash that is a serious nuisance. Much more serious though, are the roles of many species of mosquitoes as vectors of diseases. In passing from host to host, some transmit extremely harmful infections such as malaria, yellow fever, Chikungunya, west Nile virus, dengue fever, filariasis, Zika virus and other arboviruses, rendering it the deadliest animal family in ...

Summary Cell lines of baby hamster kidney (BHK 21), green monkey kidney (Vero, MA 134), rhesus monkey kidney (MA 104), and rabbit kidney (MA 111) were found suitable for titration and multiplication of arboviruses. Plaque characteristics of 52 arboviruses and 20 virus strains and titres of some of them in BHK 21 and other cell lines were established, using one type of serum-free standard overlay and standard maintenance medium. However, the addition of cortisol or other compounds was necessary to prolong survival of BHK 21 cell sheets, and induce or improve plaque formation.

Arboviruses pose a significant threat to public health worldwide causing epidemics such as Dengue, West Nile, Zika & ...
  • In recent decades, pathogenic flaviviruses (yellow fever virus, dengue [DENV], and Zika [ZIKV]) and the alphavirus chikungunya (CHIKV) have become the most common agents of emerging arbovirus diseases among humans. (
  • Although some factors are unlikely to occur in non-arbovirus-endemic settings, such as Europe, emergence of these infectious diseases in these regions may result from viremic persons with imported infections and presence of competent Aedes albopictus mosquitoes ( 2 ). (
  • Travelers are at high risk for infection by vectorborne diseases and may contribute to the spread of imported diseases in non-disease-endemic areas ( 4 ). (
  • Arboviruses pose a significant threat to public health worldwide causing epidemics such as Dengue, West Nile, Zika & chikungunya diseases with considerable repercussions for the infected hosts. (
  • Undoubtedly, tropical, rural and agricultural areas are plagued by arboviruses, while climate change, urbanization and globalization affect the geographic and seasonal patterns of vector-borne diseases, facilitating efficient reproduction of insects and the pathogens they may carry. (
  • The arboviruses are the main causative agents of infectious diseases of public health importance [ 6 ]. (
  • This manual has been prepared to provide guidelines for Human Services and local government staff, general practitioners and infection control officers involved in preventing and controlling infectious diseases. (
  • Health authorities depend on medical practitioners for information on the incidence of infectious diseases and notification is vital in efforts to prevent or control the spread of infection. (
  • These 'tails' of acute infectious diseases, herein referred to as PAISs, are characterized by an unexplained failure to recover from the acute infection, although studies of objective markers have so far been mostly unrevealing, and the pathogen rarely remains detectable by commonly used methods. (
  • The nonpolio viruses (group A and B coxsackieviruses, echoviruses, enteroviruses) are responsible for a wide spectrum of diseases in persons of all ages, although infection and illness occur most commonly in infants. (
  • Arboviral diseases caused by dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses represent a major public health problem worldwide, especially in tropical areas where millions of infections occur every year. (
  • Mosquito-borne diseases are a growing concern in Australia, and an understanding of the spatial distribution of infection is required to refine surveillance strategies and public health interventions. (
  • Because of the existence of vectors, imported mosquito-borne diseases may cause local infections and even outbreaks in areas with no previous record of a specific mosquito-borne pathogen detection. (
  • Zoonotic infections - i.e. infectious diseases that can be mutually transmitted between humans and animals - are a constant challenge for society. (
  • Disease characteristics, clinical manifestations, and epidemiology generally mimic those of enteroviral infections. (
  • These animals are exposed to the same arboviral vectors (i.e., mosquitoes) as are the urban human population, which underscores the need to better understand the epidemiology of arboviruses in wildlife. (
  • 1) describe the epidemiology, clinical manifestation, management and prevention of Zika virus disease, 2) discuss diagnostic testing for Zika virus infection and interpretation of test results, 3) articulate the importance of early recognition and reporting of cases, 4) state the recommendations for pregnant women and possible Zika virus exposure, and 5) discuss evaluation of infants with microcephaly and relationship of Zika in microcephaly. (
  • Each jurisdiction is encouraged to review its current surveillance systems in light of the local threat of WNV and emerging arboviruses (e.g., dengue and chikungunya) and ensure it is able to rapidly detect and respond to critical changes in arbovirus activity. (
  • Imported arbovirus infections (mostly dengue) were frequently diagnosed, although increased chikungunya and Zika virus infections coincided with their introduction and spread in the Americas. (
  • Chikungunya infection is confirmed via serological tests, which take about 5 to 7 days into the illness to turn positive. (

  • Fewer than 20 of the 86 known pathogenic arboviruses can be considered major causes of human disease, and 3 of these, West Nile, chikungunya, and Zika viruses, have emerged from relative obscurity within only the past 20 years. (
  • Most reports describe a self-limiting febrile illness that could easily be mistaken for another arboviral infection, such as dengue or chikungunya fever. (
  • Zika virus, yellow fever, dengue, West Nile virus and chikungunya are all types of arboviruses that affect both animals and humans. (
  • To perform a molecular screening to detect infections by the mayaro virus and possible coinfections with Chikungunya during an outbreak in the state of Tocantins/Brazil in 2017. (
  • The chikungunya (CHIKV) and mayaro (MAYV) viruses are endemic arboviruses in Brazil, belongs to the family Togaviridae (genus Alphavirus) . (
  • We report the first case of autochthonous acute chikungunya infection in Saudi Arabia. (
  • The patient had PCR negative for chikungunya, while serology demonstrated significant titres of anti- chikungunya (anti-CHICKV) IgM (31.3 NTU) as well as IgG (27.6 NTU) and this confirmed the diagnosis of chikungunya infection. (
  • 1-4 DENV used to be the only arbovirus isolated until October 2013 when FP experienced the largest outbreak of Zika virus (ZIKV) ever reported, 5,6 followed by an outbreak of chikungunya virus (CHIKV) that started in October 2014. (

  • Finally, this study discusses the complexity of the virome of Aedes and Culex mosquitoes and its implication for arbovirus transmission. (
  • The Centers for Disease Control and Prevention (CDC) recommends that health care providers test all ill returned travelers for CHIK and dengue to improve clinical outcomes, since both share endemic areas and the same Aedes vector mosquito, co-infection occurs, and no good differential diagnostic signs or symptoms exist. (
  • High-Throughput Method for Detection of Arbovirus Infection of Saliva in Mosquitoes Aedes aegypti and Ae. (
  • In this context, it is assumed that the state of São Paulo and especially its regions with large infestation of Aedes aegypti (for example, the region of São José do Rio Preto, in northwestern São Paulo) are not exempt from virus transmission risk Zika and potential clinical complications resulting from infection by this arbovirus.

  • This study addresses appropriate surveillance strategies for early detection of ZIKV infection, which is important for EMR countries with established Aedes populations, but with no known or documented autochthonous transmission of ZIKV. (
  • The WHO Regional Office for the Eastern Mediterranean developed a strategic framework for enhancing sur- veillance for ZIKV infection in EMR countries with established Aedes populations through a consultative process and review of available evidence. (
  • Zika virus (ZIKV), is an arbovirus transmitted primarily from one of the ZIKV affected countries is a possibility, by Aedes mosquitos to humans, and has caused major out- since it has happened in the recent past ( 14,15 ). (
  • ZIKV causes mild remains high in EMR countries where Aedes populations and self-limiting infection in majority of patients but and major arboviral disease outbreaks transmitted by the recent evidence indicates that ZIKV infection can be po- same Aedes species have occurred in the past ( 12,16-18 ). (
  • EMR), competent disease vector Aedes mosquitoes are and conflict, it is imperative for early detection and timely present in many countries in the Region ( 12,13 ) and a response to any cluster of ZIKV infection. (
  • Aedes aegypti mosquitoes are a persistent human foe, transmitting arboviruses including dengue when they feed on human blood. (
  • Our work mainly focuses on the interactions between arboviruses and mosquitoes. (
  • The overall question driving our research is determining why certain mosquitoes are able to serve as vectors of arboviruses, even though most mosquitoes are not. (
  • 2015. Tissue barriers to arbovirus infection in mosquitoes . (
  • While studying mosquito-borne viral infections (arboviruses) in Kenya, LaBeaud and collaborators realized that the mosquitoes were coming from the plastic trash . (
  • Because exposure to mosquitoes or ticks is the risk factor for transmission, the number of infections is highest in summer and early fall, in concordance with high mosquito populations. (
  • In addition, at least in mosquitoes, another RNAi mechanism mediated by PIWI interacting RNAs (piRNAs) is activated by viral infection. (
  • Animals become infected with arboviruses when mosquitoes carrying any of these viruses bite them, transmitting it from mosquito to animal. (
  • Enhanced arbovirus surveillance with deep sequencing: Identification of novel rhabdoviruses and bunyaviruses in Australian mosquitoes. (
  • Although Tengchong County in Yunnan Province-which borders Myanmar-is abundant and diverse in mosquitoes, very few mosquito-based arbovirus investigations have been conducted in the recent decade. (
  • A potential Japanese encephalitis epidemic focus with the abundance of host mosquitoes and high JEV infection rate was observed in Tengchong. (
  • In 2012, 27 of 47 (57%) responding public health laboratories routinely tested human specimens submitted for WNV testing for other arboviruses, but of these, only six routinely tested for arboviruses other than St. Louis or eastern equine encephalitis viruses. (
  • Arboviruses consist of more than 500 viruses from different viral families, all given the common name "ar-bo," for arthropod-borne disease. (
  • Sandflies are well known vectors for Leishmania but also transmit a number of arthropod-borne viruses (arboviruses). (
  • Furthermore, although no medically important viruses were detected, the importance of insect-specific viruses in understanding virus evolution and arbovirus transmission is discussed. (
  • Arboviruses are short for arthropod-borne viruses. (
  • Infections caused by arthropod-borne viruses, general or unspecified. (
  • More than 90% of infections caused by nonpolio entero viruses are asymptomatic or result only in an undifferentiated febrile illness. (
  • and technical assistance from CDC, a CSTE workgroup developed an assessment tool to describe human, mosquito, and laboratory surveillance capacity for WNV and other arboviruses in 2012 and to compare responses with those from 2004. (
  • To assess the effects of the opioid epidemic on invasive methicillin-resistant Staphylococcus aureus (MRSA) infections during 2005-2016, surveillance data from CDC's Emerging Infections Program (EIP) were analyzed (8). (
  • Since 2006, the US Naval Medical Research Unit No. 2 (NAMRU-2) has conducted surveillance for acute fever to determine causes of the infection among patients who seek health care at local clinics in Cambodia. (
  • However, the use of entomological surveillance for arboviral infection vector control is often dependent on finding infected individuals. (

  • This study highlights the importance of widespread and sustained mosquito-based arbovirus surveillance in local areas to prevent the transmission of JEV, and other emerging/re-emerging mosquito-borne pathogens. (
  • In Greece, the surveillance of human WNV infection is annually implemented since 2010 (in the period May - November) by the Hellenic National Public Health Organization (NPHO). (
  • In addition, enhanced surveillance of animal WNV infection (in horses and wild birds) is also implemented by the national animal health authorities. (
  • The main objective of the enhanced surveillance initiative is the timely implementation of targeted response and preventive measures to address and manage WNV infections in humans in Greece. (
  • In addition, considering the expected seasonal occurrence of cases of infection, the aim is to strengthen the surveillance and response capacity also in the medium and long term. (
  • The investigators stated that although by 2004, with the aid of federal funding, well-developed West Nile virus surveillance systems existed in almost every state, by 2012, following a 61% decrease in federal funding, many health departments had reduced such surveillance and lacked a systematic, disease-based surveillance system for other arboviruses.

  • In this Review, we summarize what is known about unexplained PAISs, provide context for post-acute sequelae of SARS-CoV-2 infection (PASC), and delineate the need for basic biomedical research into the underlying mechanisms behind this group of enigmatic chronic illnesses. (
  • The observation of unexplained chronic sequelae after SARS-CoV-2 - known as post-acute sequelae of SARS-CoV-2 infection (PASC), or 'long COVID' - in a subset of individuals has focused attention on this previously overlooked phenomenon, bringing an opportunity for accelerated progress in biomedical research into PAISs. (
  • The Viral Encephalitis Laboratory offers molecular assays on human specimens for acute arboviral infections, to assist health care providers with early diagnosis and to assist public health with emergency vector control programs. (

  • As the city of Recife in Pernambuco State, Brazil-the epicentre of the Brazilian microcephaly epidemic-has considerable disparities in living conditions, this study used an ecological approach to investigate the association between income at the neighbourhood level and the risk of ZIKV infections in pregnant individuals between December 2015 and April 2017. (
  • The spatial distribution of pregnant individuals with ZIKV infection was plotted on a map of Recife stratified into four categories based on mean monthly income of household heads. (
  • Additionally, a Poisson regression model with robust variance was fitted to compare proportions of ZIKV infections among pregnant individuals in relation to the mean monthly income of household heads, based on the 2010 census data, across 94 neighbourhoods in Recife. (

  • We detected abundant production of virus-derived siRNAs after VSV infection in adult sandflies. (
  • However, there was no production of virus-derived piRNAs and only mild changes in the expression of vector miRNAs in response to infection. (
  • Virus-derived PIWI-interacting RNAs (piRNAs) can also be generated during infection, at least in some insects. (

  • CE) - Brazil estimated cases every year and four billion people living in areas considered at risk for infection by DENV(4,6,8). (
  • Our objective with this study was to describe the epidemiologic and clinical characteristics of patients in Spain with a confirmed diagnosis of imported arbovirus infection. (
  • We do not yet understand the full spectrum of outcomes that might be associated with infection during pregnancy, nor the factors that might increase risk to the fetus. (
  • Among others results, a clearcut and consistent relationship was documented between age and sex on the one hand and acquisition of arbovirus antibodies on the other. (

  • Historically associated with hospitals and other health care settings, MRSA has now emerged as a widespread cause of community infections. (
  • It presents a difficult public health problem as the prevailing conditions clearly cannot be controlled and leptospirosis infection can result in severe disease. (
  • The Centers for Disease Control confirmed the infection on Tuesday, DPH said. (
  • Case Disease Imported Code: This variable is intended to collect the most likely location of infection, not the patient's recent travel history. (
  • Healthcare associated infections cost thousands of lives and billions of dollars every year. (
  • The West Virginia Healthcare Associated Infections (HAI) Plan was created with the assistance of our multidisciplinary advisory group. (
  • It is mostly used for people who have symptoms related to dengue fever and have recently traveled to an area where dengue infections are common. (
  • In this cross-sectional observational study, we analyzed 102 serum samples obtained from patients who consulted different health units in the state of Tocantins with symptoms of arboviral infection. (
  • The basic message is there is a possibility you could have been exposed to Zika or any other of the arboviruses by mosquito bite and though most will remain asymptomatic, a few will have symptoms and in all cases we know of people recover uneventfully from these infections,' he said. (
  • Symptoms of mild infection may last 3-6 days and include fever in 20% of cases. (
  • The clinical course of yellow fever infection leads to a variety of non-specific symptoms with severe infections potentially exhibiting fever, nausea, vomiting, jaundice, and haemorrhaging, which can result in death ( Monath and Vasconcelos, 2015 ). (
