In 2021 Multiple States Report Cases of West Nile Virus

Author: Mosquito Squad

West Nile Virus was discovered in the United States in 1999 and is the most common disease spread by mosquitoes throughout the U.S. Mosquitoes typically contract West Nile when they feed on birds that are infected. Once infected, mosquitoes can then pass the virus to humans through their bites. It has been estimated that between 1999 and 2010 over 3 million people were infected with West Nile Virus.

The risk for transmission is highest during the spring, summer, and early fall months when mosquito activity is at its highest. In 2020, the CDC received reports of human infection of West Nile virus in 36 states. This year, the CDC reports that as of May 25, 2021, 664 cases of West Nile virus in people have been reported.
