«Given that the predominant thinking was that transmission was most likely to peak at very hot temperatures, which would mostly limit the diseases to the tropics, we were certainly surprised that the model and the field data suggested that high rates of transmission could occur at lower temperatures, possibly impacting more northern regions in the future,» Cohen said.

Climate models such as the one by the Intergovernmental Panel on Climate Change predict that with rising temperatures, the conditions that favor insect vectors such as the mosquito will allow disease transmission to become more prevalent.
