Scientists from the London School of Hygiene & Tropical Medicine and the University of Michigan have discovered the first concrete evidence that the mosquito-borne disease malaria travels to higher elevations during warmer years and returns to lower altitudes when temperatures become cooler.
In research appearing in the March 7 edition of Science, the study authors reviewed records from the highland regions of Colombia and Ethiopia to see what impact climate change had on the global incidence of the ailment, which infects a reported over 300 million people annually.
Their findings reveal that, without improved monitoring and control efforts, malaria cases in some of the most densely populated regions of Africa and South America will increase significantly as the planet’s temperatures increase in the years ahead – effectively bringing the disease to areas that have traditionally faced a low risk of infection.
