"According to a CDC study, up to 75 percent of the contiguous United States may provide suitable conditions for several species of disease-spreading mosquitoes.

The recent study, published in the Public Journal of Entomology, found 71 percent of counties in the 48 contiguous states were suitable for the aegypti species and 75 percent could support albopictus species.

Researchers found that the dengue, chikungunya and Zika viruses in particular represented a “growing public health threat in parts of the United States where they are established,” according to the journal’s report."
