The Grey Bruce Health Unit is reminding residents and visitors to take precautions against mosquito bites.
Earlier this week, the Simcoe Muskoka District Health Unit identified mosquitos in Collingwood that tested positive for the West Nile virus.
The presence of the mosquito that can carry West Nile virus was confirmed in the Blue Mountains area as the result of an investigation into standing water.
The virus is transmitted through the bite of an infected mosquito. Symptoms usually develop two to 14 days after receiving a bite.
Only 20% of those infected show symptoms, such as fever, headache, body aches, fatigue, skin rash and occasionally, vomiting and nausea.
The risk of exposure to the West Nile virus can be reduced by eliminating mosquito breeding sites, including standing water in places such as bird baths, eavestroughs, flower pots and discarded tires; by wearing protective clothing; always using mosquito repellent when outdoors at dawn and dusk; and by preventing mosquito entry into the home.
