Warmer temperatures fuel spread of malaria into higher elevations
Date:3/6/2014

lsius could cause an additional 3 million additional infections in children under 15 years old each year in that population.

"Now we have evidence that this shift to higher elevations does occur," she says. Furthermore, individuals living in regions where they have not previously been exposed to malaria are more vulnerable than those in endemic regions, who have often acquired immunity from prior infections to help fight off severe disease.

"This underscores the need to sustain interventions to mitigate the effects of climate change," Pascual says. Fortunately, she adds, malaria control strategies, such as insecticides, bed nets, environmental modification, and use of efficacious anti-malarial drugs, have a higher chance of success than at lower elevations, in these regions at the edge of the distribution of the disease, where transmission rates remain relatively low even though those edges will shift as epidemic areas expand. Data from this study can be found at the Dryad Repository: doi:10.5061/dryad.dp78p.
