The Culex species of mosquitoes are the primary vector for West Nile virus in the United States and Kansas. An increase in mosquitoes, especially Culex species, may indicate an increased risk of West Nile virus (WNV) infection in humans. WNV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds.

Mosquitoes are the primary vector for many diseases, including West Nile virus. As the weather warms up, there is an increased chance for mosquito bites. The best way to prevent West Nile virus infection is to prevent mosquito bites.
