Why has the summer of 2012 proved so hospitable to the West Nile virus and the mosquitoes that carry it? Like so much else that’s gone this season, blame the weather. An extremely mild winter throughout much of the country allowed more mosquitoes than usual to survive, while the unusually high temperatures this scorching summer further increased their numbers as well as speeding up their life cycle, causing more of the virus to build up in their salivary glands….
As the summer ends, so will West Nile season. But thanks to climate change, this isn’t likely to be the last time a disease we’d usually associate with the tropics makes its way into the U.S. The mosquito-borne dengue fever, which is endemic in much of the tropics, has been reported in south Texas, as well as the Florida Keys. The first U.S. case of Chagas disease, a deadly Latin American infection transmitted by a cockroach-like bug that can feed on human blood, was reported last month. As the climate continues to warm worldwide, the zone of risk for all these diseases and even malaria could continue to expand.
