Higher temperatures make Zika mosquito spread disease more

As the temperature rises, nearly everything about the biology of the Aedes aegypti mosquito — the one that carries Zika, dengue fever and other diseases — speeds up when it comes to spreading disease, said entomologist Bill Reisen of the University of California Davis.
"With higher temperatures you have more mosquitoes feeding more frequently and having a greater chance of acquiring infection. And then the virus replicates faster because it's hotter, therefore the mosquitoes can transmit earlier in their life," Reisen said. The thermodynamics of mosquitoes are "driven by temperature"
