Climate change will affect the spread of West Nile virus and other vector-borne, disease ecologists believe, but exactly how differs from region to region, researchers say in the Proceedings of the National Academy of Sciences.
Under current climate change models, many locations will see longer mosquito seasons because of warmer temps. (Now, West Nile season is from April to September.) But hotter, drier summers will be harder on the mosquito population, shrinking the summer numbers of disease-carrying insects, researchers at the University of Arizona found, based on a new model of the mosquito population.
