Which Mosquitoes Can Transmit Disease?

The three species of mosquitoes that are responsible for spreading diseases are Aedes, Culex, and Anopheles mosquitoes. There are multiple species within these families. Thankfully, there are many types of mosquitoes that are not responsible for transmitting disease and are primarily a nuisance pest. Here in North Carolina, we have had reported cases of the Aedes mosquito.

What Diseases Do Mosquitoes Carry in the U.s.?

More than 200 types of mosquitoes are found in our nation. Of those, only about 12 types are capable of transmitting disease. The diseases that have been found in the United States include Dengue, chikungunya, Zika virus, and Malaria; these outbreaks occurred in North Carolina, Texas, Puerto Rico, Hawaii, and the US Virgin Islands. Most cases of malaria reported occur in returned travelers from tropical regions. Most types of mosquitoes we encounter are nuisance mosquitoes that are incapable of transmitting the diseases that make people sick.
