West Nile infection has been confirmed in a Lexington resident, according to the Lexington-Fayette County Health Department.
West Nile virus is spread through the bites of infected mosquitoes, and the health department will spray for mosquitoes early on Thursday in parts of the 40502, 40505, 40507 and 40508 zip codes.
In most instances of West Nile infections, people infected will show either no symptoms or relatively mild symptoms, including fever, headache, tiredness, nausea, vomiting, swollen lymph glands and rashes.
Less than one percent of infected people develop serious illnesses, such as encephalitis or meningitis. People over the age of 60 are at the greatest risk of severe disease, but serious illness can occur in people of any age.
Lexington residents can also take steps at home to fight mosquitoes, including fixing or installing window and door screens, covering or eliminating empty containers with standing water and limiting the number of breeding places by getting rid of tires, buckets, barrels and cans.
The health department also encourages residents to be aware of peak mosquito activity times around dusk and dawn. Using insect repellent during peak activity times and wearing long sleeves, long pants and socks outdoors, when weather permits, is also suggested.
