Transmission of malaria is seasonal and largely dependent on rainfall and altitude, with peaks between the months of September and December after the long rain, and between April and June during and after the short rainy season. Chemical spraying of houses in epidemic prone areas is done in the period before the transmission seasons to prevent epidemics and check seasonal peaks. Some chemicals such as DDT are strictly used for indoor spraying of houses and all necessary precautions are made to prevent contamination of the outdoor environment by these chemicals. Organophosphates use is limited to areas where DDT resistance vectors are detected.
Insecticide treated nets (ITNs) are now widely used for personal protection against malaria. Currently, ITNs are provided at highly subsidized price or free of charge, to population groups at higher risk such as non immune settlers moving to malaria endemic areas, children under five and pregnant women living in malaria risk area. However, ITNs are also available through other commercial and social marketing channels, and people living in malaria risk are encouraged to use one.
