Warming temperatures at higher altitudes are leading to higher rates of malaria in the highlands of Ethiopia and Colombia, according to a report from an international team of researchers (Siraj AS et al. Science. 2014;343:1154-1158).
Higher altitudes in the tropics typically experience seasonal periods of cooler temperatures, which can interrupt the life cycle of the malaria parasite, helping to lower the intensity of disease transmission. In recent years, questions have arisen as to whether climate warming trends are increasing the incidence of malaria in these densely populated highland regions.
