Rift Valley fever virus (RVFv) is a mosquito-borne pathogen of livestock, wildlife and humans that causes
severe outbreaks in intervals of several years. One of the open questions is how the virus persists between
outbreaks. We developed a spatially-explicit, individual-based simulation model of ...

A cross-sectional study was undertaken to determine the prevalence of ectoparasites and possible risk factors in free-range pigs from 135 farms of Busia District, Kenya.Three hundred and six pigs were examined for presence of external parasites using standard parasitological methods. Data on mana...

The principle objective of this study was to estimate the infection seroprevalence and identify risk factors associated with Theileria parva infection in cattle on smallholder farms in Machakos County, Kenya. A total of 127 farms were selected by a proportional allocation approach based on the nu...

Background
The impacts of vaccination on the transmission of Rift Valley fever virus (RVFV) have not been evaluated. We have developed a RVFV transmission model comprising two hosts—cattle as a separate host and sheep and goats as one combined host (herein after referred to as sheep)—and two vec...
