Although research is ongoing looking at other mosquitoes that might be able to vector the Zika virus (see Lancet: Global Risk Of Zika Spread Dependent Upon Competent Vectors), for now the two mosquito species of greatest concern are the Aedes Aegypti and Aedes Albopictus.
Many of the maps we've had showing their estimated range across the United States (and around the globe) haven't been been updated in several years, making regional risk assessments for Zika (and Dengue & CHIKV) difficult.
This week the CDC has released revised maps (with certain caveats attached), on their Zika Vector web page.
These maps DO NOT show
• Exact locations or numbers of mosquitoes living in an area
• Risk or likelihood that these mosquitoes will spread viruses
These maps show
• CDC’s best estimate of the potential range of Aedes aegypti and Aedes albopictus in the United States
• Areas where mosquitoes are or have been previously found
