A mosquito collected from a trap in Petrolia has tested positive for West Nile Virus.
It was the surveillance program’s first positive result for the virus in Sarnia-Lambton this year, Lambton Public Health said.
There have been no confirmed human cases locally and only two humans cases reported in Ontario as of Sept. 3.
Health officials advise residents to reduce the risk of being bitten by mosquitoes by using insect repellant containing DEET, wearing protective clothing, and taking extra precautions after dusk when mosquitoes are most active.
