Southern Florida already has a high suitability for mosquito-borne diseases because it is habitable for Aedes aegypti mosquitoes that carry viruses like those that cause Zika, dengue, chikungunya and yellow fever.[49] Future climate change projections predict that much of the Southeastern U.S. will be vulnerable to mosquito-borne diseases, particularly southern Florida which may become suitable to year-round disease transmission.[49]
