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...

Avian influenza control in Indonesia - a situation overview, pro-poor orientated research approaches of ILRI targeting backyard poultry - Preliminary results
Rift Valley fever (RVF) is a mosquito-borne viral zoonosis that is found in most regions of sub-Saharan Africa, and it affects humans, livestock, and some wild ungulates. Outbreaks are precipitated by an abundance of mosquito vectors associated with heavy persistent rainfall with flooding. We det...

Effects of irrigation and rainfall on the population dynamics of Rift Valley fever and other arbovirus mosquito vectors in the epidemic-prone Tana River County, Kenya
This study assessed the risk of transmission of highly pathogenic avian influenza (HPAI) between backyard poultry (S4) farms and between S4 and semi-commercial (S3) farms in Kenya. It was designed to complement findings of a study that had been conducted in 2007 by the DVS and FAO to evaluate the...

Qualitative release and exposure assessment on the risk of HPAI transmission between sector 4 farms and between sector 3 and sector 4 farms in Kenya
Kenya has a high risk of being infected with highly pathogenic avian influenza (HPAI) because it (i) lies along the migratory bird routes, (ii) engages in formal and informal cross-border trade in live birds and other poultry products, (iii) lacks capacity to regulate the poultry industry trade a...

Alignment of poultry sector actors with avian influenza control in Kenya
Highly pathogenic avian influenza (HPAI) was first officially reported in Indonesia in 2004; the disease is now endemic, particularly in the Java, Sumatra, Bali and South Sulawesi Islands. During the early stages of the epidemic, emergency interventions were mainly implemented by the government w...

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...

Background
West Nile fever virus is a zoonotic arboviral infection maintained in a sylvatic cycle involving mosquito vectors and birds. It is one the arboviruses whose geographical range is expanding because of climate and land use changes that enhance the densities of mosquitoes and promote mosq...

We designed and piloted a livestock identification and traceability system (LITS) along the Northern Tanzania–Narok–Nairobi beef value chain. Animals were randomly selected and identified at the primary markets using uniquely coded ear tags. Data on identification, ownership, source (village), an...
