Abstract
Aedes (Stegomyia) aegypti (L.) and Aedes (Stegomyia) albopictus (Skuse) transmit arboviruses that are increasing threats to human health in the Americas, particularly dengue, chikungunya, and Zika viruses. Epidemics of the associated arboviral diseases have been limited to South and Central America, Mexico, and the Caribbean in the Western Hemisphere, with only minor localized outbreaks in the United States. Nevertheless, accurate and up-to-date information for the geographical ranges of Ae. aegypti and Ae. albopictus in the United States is urgently needed to guide surveillance and enhance control capacity for these mosquitoes. We compiled county records for presence of Ae. aegypti and Ae. albopictus in the United States from 1995-2016, presented here in map format. Records were derived from the Centers for Disease Control and Prevention ArboNET database, VectorMap, the published literature, and a survey of mosquito control agencies, university researchers, and state and local health departments. Between January 1995 and March 2016, 183 counties from 26 states and the District of Columbia reported occurrence of Ae. aegypti, and 1,241 counties from 40 states and the District of Columbia reported occurrence of Ae. albopictus. During the same time period, Ae. aegypti was collected in 3 or more years from 94 counties from 14 states and the District of Columbia, and Ae. albopictus was collected during 3 or more years from 514 counties in 34 states and the District of Columbia. Our findings underscore the need for systematic surveillance of Ae. aegypti and Ae. albopictus in the United States and delineate areas with risk for the transmission of these introduced arboviruses.

Maps showing the reported occurrence of Ae. aegypti by county between 1 January 1995 and March 2016 in the United States. (A) Reported occurrence from 1 January 1995 through 1999, (B) reported occurrence from 1 January 1995 through 2004, (C) reported occurrence from 1 January 1995 through 2009, and (D) reported occurrence from 1 January 1995 through March 2016, representing the best knowledge of the current distribution of this mosquito based on collection records. Counties shown in white had no reported Ae. aegypti presence records within the specified time period. Counties shown in yellow had Ae. aegypti presence records for 1 year within the specified time period, those shown in orange had 2 years of presence records within the specified time period, and those shown in red had 3 or more years of presence records within the specified time period.
