Background To-date, Rift Valley fever (RVF) outbreaks have occurred in 38 of the 69 administrative districts in Kenya. Using surveillance records collected between 1951 and 2007, we determined the risk of exposure and outcome of an RVF outbreak, examined the ecological and climatic factors assoc...

Understanding the emergence and subsequent spread of human infectious diseases is a critical global challenge, especially for high-impact zoonotic and vector-borne diseases. Global climate and land-use change are likely to alter host and vector distributions, but understanding the impact of these...

Background Rift Valley Fever (RVF), is a viral zoonotic disease transmitted by Aedes and Culex mosquitoes. In Kenya, its occurrence is associated with increased rains. In Baringo County, RVF was first reported in 2006±2007 resulting in 85 human cases and 5 human deaths, besides livestock losses a...

Agriculture is a leading source of employment for rural populations in Kenya. Through a mixed methods approach, this study sought to investigate youth participation in smallholder livestock production and marketing in Baringo County. The specific focus is on how social norms and micropolitics ena...

The planet’s mean air and ocean temperatures have been rising over the last century because of increasing greenhouse gas emissions. These changes have substantial effects on the epidemiology of infectious diseases. We describe direct and indirect processes linking climate change and infectious di...

The objective of this study was to determine factors associated with occurrence of trypanosomosis in the first generation (F1) crossbreds between trypanotolerant Orma Boran and trypanosusceptible Teso zebu cattle in a trypanosomosis endemic area in Teso District, western Kenya. The offspring were...

Rift Valley fever (RVF) is a zoonotic disease of great public health and economic importance transmitted by mosquitoes. The main method of preventing the disease is vaccination of susceptible livestock before outbreaks occur. Studies on RVF vaccines have focused on the production processes, safet...

Antimicrobial agents are used widely in veterinary and human medicine worldwide. However, their use has suffered a major setback globally due to the emergence of antimicrobial resistance (AMR) in a wide range of microorganisms. This study aimed to investigate the prevalence of AMR in household mi...

We examine two widely used treatment strategies for African animal trypanosomosis in West Africa: preventive drug control ex-ante trypanosomosis infection and curative drug control ex-post trypanosomosis infection. We investigate which combination of these alternative strategies is economically o...
