UPDATE: Which Louisville zip codes contain mosquitoes that tested positive for West Nile?

LEXINGTON, Ky. (AP) - Officials have confirmed the presence of the West Nile virus in Kentucky's two largest cities.

The Lexington-Fayette County Health Department said in a statement on Wednesday that a resident had contracted the disease and officials would conduct mosquito-spraying activities in four zip codes. Meanwhile, the Louisville Metro Department of Public Health and Wellness said it had found infected mosquitoes in six zip codes.

Sarah Moyer, director of Public Health and Wellness in Louisville, said in a statement that it's common to find infected mosquitoes at this time of year. She said residents could take precautions such as wearing bug repellant outside at dusk and dawn and removing standing water from around homes.

Between 2012 and 2016, Kentucky has averaged about 10 cases of West Nile virus, which is contracted from the bite of an infected mosquito, per year.

This year Louisville's health department has identified mosquitoes carrying the virus in neighborhoods with the following zip codes: 40204, 40205, 40206, 40208, 40212 and 40214. 

You can reduce your chances of getting the virus by avoiding mosquitoes, particularly between dusk and dawn when they're most active. The Kentucky Department for Public Health recommends the following precautions:

Most people infected by the virus have mild symptoms, but serious illness can occur.

Last year, one Louisville resident died from the virus.
