Higher temperatures mean increased biting rates by female Aedes mosquitoes, increasing the risks of disease transmission. The same higher temperatures speed up the spread of the viruses the mosquitoes carry.

Both increased temperatures and rainfall stemming from climate change will expand the geographical distribution of dengue — increased temperatures shorten the mosquito breeding lifecycle, and more rainfall delivers more places for mosquitoes to breed and the humidity they need to thrive.
