High Mosquito Counts Identified in Kansas

Mosquitoes are Culex Species That Transmit West Nile Virus

Topeka, Kan. – The Kansas Department of Health and Environment (KDHE) has identified a high number of Culex species mosquitoes in traps located in Sedgwick County. This increase in the number of mosquitoes is likely to be statewide, which could make West Nile virus transmission more likely to occur earlier than in previous years. The Culex species are known to transmit West Nile virus; they are not known to transmit Zika virus.

West Nile virus is most commonly spread to people through bites from infected mosquitoes, and it is not contagious from person to person. Symptoms range from a slight headache and low-grade fever to swelling of the brain or brain tissue and in rare cases, death. People who have had West Nile virus before are considered immune.

KDHE recommends the following precautions to protect against West Nile virus and other mosquito-borne diseases:

Cases are most common in the late summer and early fall months. In 2012, there were 57 cases of West Nile virus in the state, the most cases since the virus first made its way into Kansas in 2002. More recently in 2015, 34 cases were identified in Kansas; more than half of these cases were hospitalized. In addition to tracking cases of human illnesses caused by West Nile virus, KDHE assesses the potential for West Nile virus by conducting limited mosquito surveillance, including laboratory testing.

Birds are not tested for West Nile virus in Kansas and KDHE will not be collecting information about dead birds. If you find a dead bird, KDHE recommends that you wear gloves, place the bird in a plastic bag, and dispose of it in the garbage.
