51 - Re-emergence of Aedes aegypti in the Florida Panhandle

Aedes aegypti is an invasive mosquito vector that is present within the southern and eastern United States. Historically, Ae. aegypti was replaced by Aedes albopictus in north Florida through satyrization, but has recently been found in several counties north of its recently observed range.  After almost 30 years of absence in this area, multiple observations of Ae. aegypti have been made across 2 counties in the Florida panhandle in 2023. It is currently unknown if this range expansion will be sustained or if these are isolated observations. Regardless, Ae. aegypti is a significant threat to public health and will continue to be monitored for presence/absence within this geographic area.
