LOUISVILLE, Ky. (WDRB) -- Mosquitoes with West Nile virus have been found in Louisville.

The Department of Public Health and Wellness said in a release that surveillance traps in three local zip codes turned up infected mosquitoes including 40212, 40213, and 40214.

No human cases of West Nile have been reported in Louisville so far this year. But one person was infected last year and survived. in 2016, two people contracted the disease with one death.

Health department director Dr. Sarah Moyer said in the release that precautions should be taken.

“We advise everyone to take the appropriate precautions no matter what ZIP Code you live in," she said, in a statement. "You should wear insect repellant if you go outside during dusk or dawn and should remove standing water around your home.”

People infected with West Nile virus may show no or very mild symptoms. Less than one percent of those infected develop serious illness of the nervous system like encephalitis or meningitis.

Those who are 60 years of age or older are at the greatest risk along with those who have medical conditions like cancer, diabetes, hypertension, kidney disease, and or who have received organ transplants.

The health department operates a mosquito control program and checks traps set in the community to test for diseases like West Nile, Zika and St. Louis Encephalitis.

The Department of Public Health and Wellness advises people to take precautions to avoid mosquito bites:

•Use insect repellents containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection. Information about insect repellents can be found by visiting http://www.cdc.gov/westnile/faq/repellent.html.

•When weather permits, wear long sleeves, long pants and socks when outdoors. Do not spray repellent on the skin under your clothing.

•Take extra care during peak mosquito biting hours from dusk to dawn.

The health department also suggests mosquito-proofing your home by installing screens on windows and doors and using air conditioning, if available. You can also reduce the number of mosquitoes around your home by eliminating standing water in gutters, buckets pool covers, pet dishes and birdbaths.
