Animal diseases have a major impact on crop-livestock systems in West Africa. The productivity of all crop-livestock systems is limited both by the direct effects of overt disease and by strategies that are adopted to mitigate disease risk. Epidemic diseases require substantial expenditures to li...

We quantified the between-village transmission rate, β (the rate of transmission of H5N1 HPAI virus per effective contact), and the reproductive number, Re (the average number of outbreaks caused by one infectious village during its entire infectious period), of H5N1 highly pathogenic avian influ...

We carried out a participatory risk assessment to estimate the risk (negative consequences and their likelihood) from zoonotic Cryptosporidium originating in dairy farms in urban Dagoretti, Nairobi to dairy farm households and their neighbours. We selected 20 households at high risk for Cryptospo...

Since the first reported outbreak of highly pathogenic avian influenza (HPAI) H5N1 in Nigeria in 2006, there
have been approximately 300 reported cases as at the end of August 2008, of which more than half occurred
on backyard commercial farms. A case-control study was conducted in the two states...

Rift Valley fever is a viral zoonosis that primarily affects people, cattle, sheep, goats, camels, buffalos, dromedaries, antelopes and wildebeest. The two most recent RVF epidemics in Kenya occurred in 1997/1998 and in 2006/2007 with severe socio-economic consequences in multiple sectors of the ...

In controlling Rift Valley fever, public health sector optimises health benefits by considering cost-effective control options. We modelled cost-effectiveness of livestock RVF control from a public health perspective in Kenya. Analysis was limited to pastoral and agro-pastoral system high-risk ar...

There is a need to find locally and globally relevant surveillance tools to measure disease prevalence and
inform control programs. Traditional veterinary knowledge has a contested role in surveillance systems.
We examined participatory epidemiology (PE) surveys for agreement between community pe...
