In another study, APHIS wildlife disease specialists collaborated with University of Missouri researchers to capture and sample rats in fall 2021 in and around the New York City sewage system. (avma.org)

The persistence, emergence and re-emergence of these diseases is mainly attributed to the scarcity of trained vector-control experts. (who.int)
Comparative approaches have unveiled diverse evolutionary patterns, highlighting both stable host-virus associations over extended evolutionary timescales and much more recent viral emergence events. (researchgate.net)
The concept, definition and factors contributing to the emergence of disease threats were encapsulated in two reports from the US Institute of Medicine that defined the major issues and described the principal causes and mechanisms leading to infectious disease emergence, as well as discussing possible strategies for recognizing and counteracting the threats. (who.int)
Many factors or combinations of factors contribute to disease emergence. (who.int)
10,11 Other factors that contribute to emergence are microbial mutation and selection and genetic re-assortment that can lead to the development of new genotypes of known diseases, as we see most frequently with influenza A and also in new patterns of antibiotic resistance. (who.int)

Overall, our research activities are targeted towards a better understanding of virus biology and virus-induced host responses to foster the development of vaccines and therapeutics. (nih.gov)

The training course attempts to fill the gap in trained manpower and thus reduce the morbidity and mortality due to these diseases, resulting in incremental gains to public health. (who.int)
This will bring new insights to the policy makers and provide information for the scenario planning of public health authorities to decrease the risk of actual deaths due to the disease (mortality). (lu.se)
Tuberculosis (TB) (see the image below), a multisystemic disease with myriad presentations and manifestations, is the most common cause of infectious disease-related mortality worldwide. (medscape.com)

The presence of this reservoir host seriously threatens ongoing efforts to eradicate this disease from cattle. (usda.gov)

Recent studies provide evidence that the Angolan free-tailed bat (Mops condylurus), an insectivorous microbat, is a possible ebolavirus reservoir. (researchgate.net)

The research objectives are to study the viral lifecycle and the virus-induced host responses to identify targets of intervention and to develop measures of prevention. (nih.gov)
Cats and stoats can act as hosts of TBE virus. (dtic.mil)

Just last month, for example, scientists pinpointed camels as the direct source of the virus responsible for Middle East respiratory syndrome 3 , 4 , a new disease that has claimed more than 300 lives since it was discovered in 2012. (nature.com)

India's southern Kerala state has shut down schools and offices and declared containment zones in parts of the state amid the risk of an outbreak of Nipah virus following the death of two people from the rare and deadly brain-damaging viral disease. (aljazeera.com)
What Do We Know About Marburg Virus Disease? (medpagetoday.com)
The World Health Organization announced that Equatorial Guinea confirmed its first outbreak of Marburg virus disease , after one sample tested positive. (medpagetoday.com)
Here is what the scientific community has learned so far about Marburg virus disease. (medpagetoday.com)
The first known human cases of Marburg virus disease were reported in 1967 in Marburg and Frankfurt, Germany, and in Belgrade, Yugoslavia (now Serbia), when laboratory workers handling African green monkeys imported from Uganda became ill, followed by several healthcare providers and family members, for a total of 31 cases, according to the CDC . (medpagetoday.com)
He fully recovered, and was retrospectively diagnosed with Marburg virus disease. (medpagetoday.com)
The reservoir host of Marburg virus is Rousettus aegyptiacus , the African fruit bat , a sighted cave-dwelling bat found across Africa. (medpagetoday.com)
There are no vaccines or antiviral treatments approved to treat Marburg virus disease. (medpagetoday.com)
However, the association between the seroprevalence and host abundance could be related with a threshold population density below which the virus is prone to experience local extinction. (conicet.gov.ar)
Little cherry is a symptom of little cherry disease, caused by little cherry virus -1 and -2 and X-disease (caused by Candidatus Phytoplasma pruni). (oregonstate.edu)
The host is distributed across sub-Saharan Africa while the virus' range appears to be restricted to West Africa. (folkhalsomyndigheten.se)

Pneumonic forms of plague can occur primarily, without antecedent bubonic disease, or, secondarily, due to dissemination of bubonic disease. (strategypage.com)

Seeking answers, Goldberg is now calling for a systematic effort on the part of disease ecologists, epidemiologists and social scientists to understand all the ways by which diseases might find their way from nature into human hosts. (nature.com)
However, monkeys and apes are only one potential reservoir for new human diseases. (nature.com)
The two-host life cycle of this tapeworm comprises human beings as definitive hosts and swine as intermediate hosts. (who.int)
Human beings can also become intermediate hosts, however, by directly ingesting T. solium eggs shed in the faeces of human carriers of the parasite. (who.int)
Human cysticercosis is a disease associated with poverty in areas where people eat pork and traditional pig husbandry is practised. (who.int)
While some select agents are normally found in the environment and don't cause human disease, many of them - if manipulated or released in large quantities - can cause serious health threats. (who.int)
Given the resurgence of both human and animal trypanosomiasis, the epidemic potential, high fatality rate and significant impact on socioeconomic development, many countries requested more active WHO support to control the disease. (who.int)

In over 20 years in public service, he was deeply engaged in investigating emerging viral diseases, such as viral encephalitis, dengue, yellow fever, and Lassa fever, affecting underserved countries in Africa and Latin America. (forextv.com)

Clinical and epidemiological features of the disease were also compared. (bvsalud.org)

Unlike other rickettsiae, which target vascular endothelial cells, R akari targets host CD68 macrophages. (medscape.com)

Types include an obligate host, definitive (primary) host, intermediate host and a transport host. (powershow.com)

Prevalence is a product of incidence x duration of disease, and is of little interest if an infectious disease is of short duration (i.e. measles), but may be of interest if an infectious disease is of long duration (i.e. chronic hepatitis B). (powershow.com)

In Uganda, we focus on vector-borne diseases including Crimean-Congo hemorrhagic fever and Rift Valley fever. (nih.gov)
The objective is to create a core of experts trained to prevent and control vector-borne diseases. (who.int)
The course is a response to the serious health and socioeconomic burden caused by a number of vector-borne diseases in Pakistan. (who.int)
10 vector-borne diseases, accounting lack of trained medical entomologists the opportunities and chal enges that for 11% of the global burden in an area and vector-control experts to prevent would influence the sustainability of the where only 8% of the global population and control any adverse health impacts. (who.int)

Or, where not fatal, to suppress the disease burden with diminishing the number of people who suffer from the disease (morbidity) in a certain period of time, for the population at risk. (lu.se)

Despite the name, it is not known if primates such as monkeys are more than incidental hosts. (spokesman.com)
