ILRI research generates evidence for better prevention and control of zoonotic diseases

ILRI/Yvane Marblé).

World Zoonoses Day, celebrated annually on 6 July, commemorates the day in 1885 when Louis Pasteur successfully administered the first vaccine against a zoonotic disease. It is also a day to raise public awareness of the risk of zoonotic diseases and how to effectively prevent and control them.

The International Livestock Research Institute (ILRI) has a wealth of research expertise on zoonoses. Through its Animal and Human Health program, ILRI works with national and international partners to improve the control of zoonotic diseases through various approaches such as risk mapping and risk targeting, modelling of zoonotic pandemics, decision-support tools and advice on vaccination strategies. The program also generates evidence for policymakers on the cost and impact of zoonoses and the benefits of their prevention.

Our collaborative research projects on zoonoses include examining zoonotic infections among livestock and the farmers who keep them; developing optimal vaccination strategies for Rift Valley fever in East Africa; studying the epidemiology, ecology and socio-economics of disease emergence in Nairobi; developing a surveillance program for zoonoses in livestock in Kenya; identifying anthrax hotspots and ecological risk factors in Kenya and determining the burden of Rift Valley fever, brucellosis and Q fever co-infection in people, livestock and wildlife in Kenya.

To explore our research in more detail, below is a list of recent peer-reviewed articles on zoonoses by ILRI scientists and partners.
