First Human Case of West Nile Virus 2023

Point Edward, ON - A Lambton County resident has tested positive for the West Nile virus (WNV). This is the first lab confirmed human case of the virus locally in 2023.

There have been 41 human cases reported in Ontario. WNV was previously established in our area through local surveillance efforts. Mosquito pools in Wyoming, Sarnia, Corunna and Forest tested positive earlier this season.

This positive human case is a reminder for Lambton County residents to remain vigilant in taking precautions to prevent exposure to mosquitos and to eliminate mosquito breeding sites on their property.  Despite lower nightly temperatures, the current mosquito season is not over until frost and cold temperatures halt mosquito breeding.

WNV is spread to humans through the bite of an infected mosquito. Reduce your risk:

• Take precautions to avoid mosquitoes and bites.
• Remove or reduce areas of standing water during fall clean-up.
