Durham Region Health reports season’s first West Nile pools

Durham Region Health Department has received notification of adult mosquitoes that have tested positive for West Nile virus (WNV). The two separate positive mosquito pools were collected from one of the Health Department’s permanent mosquito trap sites located in Ajax. Positive confirmation was received. These are the first mosquitoes in Durham Region to test positive for WNV this season.

“With this West Nile-positive mosquito result, it’s important for area residents to take precautions to avoid mosquito bites and remove standing water from their properties,” said Ross MacEachern, Manager, Health Protection with the Health Department.

WNV is a mosquito-borne disease that is spread to humans via the bite of an infected mosquito. Mosquitoes become infected by feeding on the blood of a bird that carries the virus. The disease is not passed from person to person or from bird to person. Most people who contract the virus will experience mild illness including fever, headache, body ache, nausea, vomiting, and rash on the chest, stomach or back. More serious symptoms can include muscle weakness, stiff neck, confusion, tremors, numbness and sudden sensitivity to light.

For more information on WNV, please call the Health Department’s Environmental Help Line at 905-723-3818 or 1-888-777-9613, or visit durham.ca/WestNile.
