Abstract

Climate variability resulting from events such as El Niño increases the likelihood of malaria transmission in western Kenya. This study measures vectors collected in western Kenya highlands in four selected villages, categorized into two valley systems, the U-shaped (Iguhu and Emutete) and the V-shaped valleys (Marani and Fort Ternan) over an eight month period. Results show how the changing malaria transmission rates in the highlands will lead to more unstable transmission, decreased immunity and a high vulnerability to epidemics, unless surveillance tools are improved and effective vector control is sustained.
