Currently new human diseases are emerging at the rate of one every four months. Around 20%of human emerging diseases are caused by antimicrobial resistant pathogens and around 75% are zoonotic. Diseases are also emerging in livestock, companion animals, wildlife and plants. A systematic literatur...

The International Livestock Research Institute (ILRI) was created in the early 1990s, and, like CGIAR crop centres, its major goal was increasing productivity. Animal health was believed to cause about one-fourth of the yield gaps seen in developing countries, but almost all research centreed on ...

Introduction Rift Valley fever virus (RVFV) transmission gets elevated following periods of excessive and persistent rainfall. The average inter-epizootic period in Kenya has been estimated to be 3.6 years (range 1–7 years). It is presumed that herd immunity plays an important role in modifying t...

Rift Valley fever (RVF) is a zoonotic vector-borne disease present in much of Africa, and the Arabic peninsula. During outbreaks, the case fatality is high in young ruminants and there may be abortion storms, human disease is usually mild but some may suffer fatal hemorrhagic fever. Outbreaks in ...

Rift Valley Fever (RVF) is an acute mosquito-borne viral zoonosis that causes cyclical epidemics in sub-Saharan Africa, with recent incursions into the Arabian Peninsula. Outbreaks of RVF are associated with above average rainfall and flooding, in which large numbers of vectors emerge. Recent stu...
