Public Health officials are warning that West Nile virus (WNV) could be buzzing around your backyard.
A dead crow in Guelph has tested positive for the virus.
Wellington-Dufferin-Guelph Public Health said there are no human cases in the region, but the case in the crow confirms mosquitoes could be carrying the virus nearby. Officials are warning residents to take the necessary precautions to reduce mosquito bites.
“Although the risk in our region is low, WNV is still present, and people should stay vigilant,” said Associate Medical Officer of Health, Wellington-Dufferin-Guelph Public Health, Dr. Matthew Tenenbaum.
“We continue to monitor and control local mosquito populations, but it is important for everyone to take the basic steps that help prevent mosquito bites.”
Those steps include:
- Wear light-coloured, long-sleeved shirts and pants, especially outdoor at dawn and dusk.
- Use Health Canada-approved mosquito repellent.
- Repair window and door screens.
- Drain standing water from property (e.g., flowerpots, birdbaths, kiddie pools, clogged gutters).
West Nile symptoms include fever, headache, body aches, fatigue, nausea or vomiting, and usually don’t show until two to 14 days after an infected bite.
In very rare cases, health officials say it can cause inflammation of the brain or spinal cord.
