Mosquitoes test positive for West Nile in Knoxville

Mosquitoes test positive for West Nile in Knoxville

"While human incidence of West Nile Virus is rare, it is a risky disease with no cure or vaccine for people, so residents should protect themselves by preventing mosquito bites", Public Health Director Phillip Tarte said in a statement.

West Nile Virus can be deadly - but only one in five people who are infected by a mosquito bite will develop any symptoms, according to the South Carolina Department of Health and Environmental Control. The virus was previously confirmed in Lehigh County this year.

Last year, there were 39 laboratory-confirmed human cases of the virus reported to Toronto Public Health.

Public Health says the risk to get infected still remains low, but recommends taking precautions to avoid getting bitten.

"As we head into late summer, we know that residents and visitors to Toronto are maximizing their time outside to enjoy the weather and outdoor activities", Dr. Eileen de Villa, Toronto's medical officer of health, said in a news release Tuesday. The first case in 2018 was reported on July 27.


Older people who have compromised immune symptoms face a higher risk of severe illness. They can include fever, headache, nausea, vomiting, body aches, skin rash and swollen lymph glands.

To reduce the risk of contracting West Nile, you are advised to apply insect repellant often, dispose of standing water around your home and wear socks, long, loose and light-colored shirts and trousers.

Use insect repellents when you go outdoors. Also apply insect repellent containing DEET especially during dawn and dusk which are peak mosquito biting hours.

It doesn't take much standing water for mosquitoes to breed.
