In a recent article, Zhou et al. Malaria epidemics in the highlands of East Africa garner significant research attention, due, in part, to their proposed sensitivity to climate change. These factors are likely behind the high rates of poverty among the populations. The role of climate change in the exacerbation of the disease has been controversial, and the specific influence of rising temperature (warming) has been highly debated following a previous study reporting no evidence to support a trend in temperature. A small increase in temperature could have led to the recent dramatic rise in malaria in the highlands of East Africa, say researchers.

East African highlands are one of the most populated regions in Africa. In Southern Africa, countries have recently experienced malaria epidemics following unusual rainfall. The causes of the recent re-emergence of malaria in the East African highlands probably involve a complex interplay among multiple factors, including climate, land use, topography, inadequate use of antimalarial drugs and drug resistance, socioeconomic status, health policy and public health control measures. On the island of Bataan, 85% of American and Filipino troops were malaria-struck when they … epidemics were reported in eastern Africa highlands (Fontaine et al., 1961). We use these data in support of our hypothesis that drug resistance is a key ele-ment in highland malaria epidemics in East Africa, and we examine how past control might guide future efforts to reduce the clinical impact of epidemics. An increasing altitudinal range implies the potential for an increased burden of malaria with climate change, especially for countries of East Africa and South America with densely populated highlands that have historically provided havens from this devastating disease . Records from tea estates in the Kericho district of western Kenya highlands showed that malaria re-emerged in the 1980s (Shanks et al.,2005) The population densities in the highlands ranged between 158 persons/km2 in Ethiopia and 410 persons/km2 in Rwanda. In recent decades, malaria has become established in zones at the margin of its previous distribution, especially in the highlands of East Africa. Stable endemic malaria predominates throughout the continent, but epidemics occur at the fringes of endemic areas, particularly among communities at the southernmost latitudes, across the arid regions of North Africa, and among the highlands of East, central, and Horn of Africa (5,6). The incidence of malaria in the East African highlands has increased since the end of the 1970s. According to the United Nations Population Fund, the region has the world's highest population growth rate. long-term epidemiologic transition of malaria in 1 district of the western highlands of Kenya. Their study, published online by the Proceedings of the National Academy of Sciences, contradicts previous research that found no increase in temperature in areas where the incidence of malaria was on the rise. Malaria epidemics were not reported between the 1960s and the early 1980s after a malaria eradication campaign (Roberts, 1964a,b,c). Malaria afflicted 60% of them in South-East Asia.
