Estimated range of Aedes albopictus and Aedes aegypti in the United States, 2017
Filetype[PDF-559.19 KB]

  • Description:
    Aedes aegypti mosquitoes are more likely to spread Zika, dengue, chikungunya, and other viruses than other types of mosquitoes such as Ae. albopictus mosquitoes. CDC has updated the estimated range maps for Ae. aegypti and Ae. albopictus mosquitoes by using a model that predicts possible geographic ranges for these mosquitoes in the contiguous United States. The model used county-level records, historical records, and suitable climate variables to predict the likelihood (very low, low, moderate, or high) that these mosquitoes could survive and reproduce if introduced to an area during the months when mosquitoes are locally active. These maps include areas where mosquitoes are or have been previously found. Maps do not represent risk for spread of disease. Ae. aegypti mosquitoes are more likely than Ae. albopictus mosquitoes to spread viruses like Zika, dengue, chikungunya and other viruses. CS264451-F Zika-mosquito-maps.pdf
