Mosquitoes Test Positive for West Nile Virus in Knox County

KNOX COUNTY, Ind. (We Are Knox County) - Health officials are warning residents to take precautions after mosquitoes in Knox County tested positive for West Nile virus.

The Knox County Health Department says the State of Indiana confirmed the virus after entomologists set traps throughout the state to catch mosquitoes and test them for the presence of West Nile virus.

"While it is not unusual to have mosquitoes in Knox County test positive for the West Nile virus, it is important to be aware of the risks," the Knox County Health Department said in a statement.

The health department says about 20% of people infected with West Nile virus develop symptoms, which can include fever, headache, muscle aches, fatigue and malaise.

"More severe neurologic symptoms may occur in about 1 in every 150 people who are bitten," the department said.

The Knox County Health Department recommends removing or repairing any potential items on your property that could serve as breeding grounds for mosquitoes.

"This would include removing old tires, old containers or other items that can retain water, keeping grass cut short, cleaning clogged gutters, and emptying containers that are used to hold water at least once per week."

Officials also recommend using insect repellent containing DEET and avoiding mosquito bites by limiting outdoor activity after sunset and before sunrise.

Knox County Health Officer Dr. Alan Stewart said he is not aware of any human cases of West Nile virus occurring in Knox County.
