From Nature News:

Climate change takes the blame for many dim future prospects: rising sea levels, more frequent droughts and disappearing glaciers, to name just a few. But perhaps the warming trend should be absolved of responsibility for a predicted bump in the global burden of infectious disease.

That's the bottom line of a paper in the April issue of the journal Ecology, which argues that the geographical ranges of infectious diseases are more likely to shift than to expand (K. D. Lafferty Ecology 90, 888–900; 2009). "You often see a list of the 12 terrible things that are going to happen with climate change, and increases in infectious diseases is often on that list," says Kevin Lafferty, an ecologist with the US Geological Survey in Santa Barbara, California. But data from diseases such as yellow fever and malaria, he says, provide "a different reality".
