Current information about climate change leans towards the fact that inter- annual and inter-decadal climate variability have a direct influence on the epidemiology of vector-borne diseases.
The current discussions on climate change estimate that average global temperatures will increase the likelihood of many vector borne diseases in tropical countries like Kenya.
Malaria and dengue fever are among the most important vector borne diseases in tropical climates like the one we experience here in Kenya.
Human settlements in different parts of Kenya will influence disease trends. The proportion of urbanized Kenyan population is less that 45%. Climatic anomalies associated with the Elnino- Southern Oscillation phenomenon and resulting in drought and floods are expected to increase in frequency and intensity. These conditions have in the past been linked to outbreaks of highland malaria in Kenya. Climate change has far reaching consequences and touches on all life-support systems. This is a factor that should be placed high among those that affect human health and survival for people living in the tropics.
Objectives: The main objective of this review is to demonstrate from literature the underlying principles of the effect of climate change on vector borne disease transmission and to highlight the malaria experiences in Kenya.
Methodology: Review literature globally including whatever is available in Kenya.
Expected output: To prepare a firm ground for a concept note aimed at conducting a comprehensive study of the scenario in Kenya. Armed with such information, the health system will be better placed to respond appropriately to the changing situation.
