LOUISVILLE, Ky. (WDRB) -- Louisville health officials have found mosquitoes infected with the West Nile virus in the Tyler Park neighborhood and areas surrounding it near the Highlands.

In a news release Tuesday, the Louisville Metro Department of Public Health and Wellness said mosquito fogging will take place this week in an area stretching west to east from Barret Avenue to Willow Avenue and north to south from Patterson Avenue to Deer Park Avenue.

"This is about the time of year we typically see mosquitoes test positive for West Nile," Connie Mendel, Louisville’s chief health strategist, said in a news release. "No matter what ZIP code you live in, please take precautions to avoid being bitten."

Mosquito fogging is intended to help prevent infection and reduce the mosquito population. There have been no human cases of West Nile Virus reported this year in Jefferson County.

In most cases, people infected with the virus have mild to no symptoms. Less than 1% of infected people have gotten a serious neurologic illness like encephalitis or meningitis. People over the age of 60 and those with medical conditions like cancer and diabetes are more susceptible for serious illness. 

Here are some steps you can take to avoid being bitten by mosquitoes: 

  • Use insect repellents when you go outdoors. Repellents containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection. To optimize safety and effectiveness, repellents should be used according to the label instructions. 
  • When weather permits, wear long sleeves, long pants and socks when outdoors. Mosquitoes may bite through thin clothing, so spraying clothes with a repellent containing permethrin or another EPA-registered repellent will give extra protection. Don't apply repellents containing permethrin directly to your skin. Do not spray repellent on the skin under your clothing.
  • Take extra care during peak mosquito biting hours of early morning and dusk. Take extra care to use repellent and protective clothing from dusk to dawn or consider avoiding outdoor activities during these times.
  • Prevent mosquito breeding grounds:
  • Install or repair screens on windows and doors to keep mosquitoes outside.
  • Help reduce the number of mosquitos around your home by emptying standing water from flowerpots, trash cans, gutters, buckets, pool covers, pet water dishes, discarded tires and drain birdbaths on a regular basis.

To make a complaint about mosquitoes in your neighborhood, call 311 or 502-574-5000.
