On June 20, 2017, the CDC announced that the Southern United States showed a substantial increase in the number of counties that reported evidence of the mosquitoes that can spread chikungunya, dengue, and Zika viruses, according to new research by the CDC.
In the spring and fall of 2016, the CDC conducted surveys to record where Aedes aegypti and Aedes albopictus mosquitoes were found. The latest 2016 data added Ae. aegypti collection records from 38 new counties and Ae. albopictus collection records from 127 new counties, a 21 percent and 10 percent increase, compared with the previous report, in the number of counties that reported the presence of these mosquitoes.
These findings highlight the need for continued and improved mosquito surveillance. State and local health departments and mosquito control districts can use this information to plan for mosquito control and prevention activities in advance of possible outbreaks of mosquito-borne diseases.
