Kentucky health officials have issued a statewide alert following an increase of mosquito-borne illnesses.
Cases of West Nile virus and La Crosse virus, both spread by the bite of infected mosquitos, rose dramatically in Kentucky between late August and late September.
In total, 19 cases of West Nile virus have been diagnosed in Kentucky, with one death, compared to an average of seven cases per year “in previous years,” according to the Kentucky Medical Association (KMA).
In addition, there have been two confirmed cases of La Crosse virus, and two suspected cases are under investigation in eastern and central Kentucky.
“This is compared to only 11 cases (of La Crosse virus) reported in total in Kentucky from 2003 to 2024,” the KMA said.
Nine of the West Nile virus cases are in Jefferson County while four are in Fayette County. Seven of the Louisville patients required hospitalization, according to LouisvilleKY.gov, while all four of the Fayette County patients were hospitalized.
The KMA says: “Common symptoms of West Nile and La Crosse infections include fever, fatigue, headache, rash, myalgias, nausea/vomiting and diarrhea. Most infections cause little to no symptoms leading to underreporting.”
“In severe cases, these arboviruses can cause neurologic disease including meningitis, encephalitis and acute flaccid paralysis,” according to the KMA.
Mosquito prevention tips:
- Be aware of peak mosquito activity from dusk to dawn
- Use EPA-labeled repellents containing DEET, Picaridin or oil of lemon eucalyptus
- Wear long sleeves, long pants and socks when outdoors
- Spray clothing with permethrin-containing repellent
- Fix or install window and door screens
- Eliminate standing water around homes, including in tires, gutters, flowerpots, pet dishes and birdbaths
