Health officials are looking into two potential human cases of the West Nile virus in Simcoe County.
To protect yourself from West Nile virus, officials recommend wearing light-coloured trousers and a long-sleeved shirt when outside.
"The Town of Bradford West Gwillimbury has historically been identified as an area with increased risk for the virus", the health unit wrote in a news release. Avoid being outdoors when mosquitoes are most active, at dusk and dawn. Mosquitoes acquire the virus by feeding on infected birds.
Symptoms of west nile include high fever, headaches, muscle aches, vomiting and loss of appetite. During that time, people should wear insect repellent to prevent mosquito bites, the board of health said.
Around 80 percent of those who are infected with WNV do not get sick.
The Wisconsin Department of Health Services has monitored the spread of West Nile virus since 2001 among wild birds, horses, mosquitoes, and people.
The first local cases of West Nile virus this year have been reported. In humans, West Nile can cause flu-like symptoms.
Mosquito pools in Waterloo Region, Wellington-Dufferin-Guelph, Huron-Perth and Grey-Bruce have all tested positive for the virus this year.
