Dead crow tests positive for West Nile
Risk remains low but people should still try to avoid mosquito bites: public health
GUELPH – A dead crow found in Guelph has tested positive for West Nile virus.
"While there are currently no human cases in the region, a positive local bird suggests mosquitoes carrying the virus may be present," states a June 2 press release from Wellington-Dufferin-Guelph Public Health (WDGPH).
Associate medical officer of health Dr. Matthew Tenenbaum said regional risk and the risk of severe illness remains low, but he nonetheless recommended vigilance to reduce bites.
West Nile is spread through the bite of an infected mosquito. Summer and early fall are high-risk times as mosquitoes are most active.
Symptoms usually begin two to 14 days after a bite and may include fever, headache, body aches, fatigue, nausea or vomiting, according to public health.
However most people infected with West Nile do not develop symptoms.
In rare cases serious illness like inflammation of the brain or spinal cord can occur. There is no specific treatment.
WDGPH officials recommend:
• wearing light-coloured, long-sleeved shirts and pants, especially outdoors at dawn and dusk;
• using Health Canada-approved mosquito repellent;
• repairing window and door screens;
• draining standing water from property (e.g., flowerpots, birdbaths, kiddie pools, clogged gutters); and
• contacting a health care provider if you develop symptoms after a mosquito bite.
