A mosquito collected in the Municipality of Meaford tested positive for West Nile virus (WNv). The positive mosquito re-affirms the presence of the virus in mosquito pools in our area. The Grey Bruce Health Unit will continue weekly trapping of mosquitoes and have them identified and tested at a laboratory. If you see a trap, please do not touch it.
Individuals can become infected after being bitten by an infected mosquito. In 2018, there have been no confirmed cases of WNv in humans in Grey and Bruce Counties.
The best way to prevent West Nile virus is to avoid being bitten. Reduce mosquito habitats by preventing standing water, which is where mosquitoes lay eggs. The Public Health Agency of Canada recommends the following when heading outdoors when mosquitoes are most active (e.g., dawn and dusk):
-
Cover exposed skin
-
Wear long pants and loose-fitting shirts with long sleeves
-
Socks and a hat (even put mosquito netting over your hat)
-
Wear light coloured clothing
-
Use bug spray that contains either DEET or Icaridin
Please speak to your health care provider if you are concerned about your health. Most people infected with WNv have no symptoms.
For others, symptoms may occur within 2 to 15 days after infection. Symptoms can be mild to severe. Mild symptoms may include fever, headache, body aches, mild rash, or swollen lymph nodes. Recovery can take a week for mild cases. Adults 50 years or older and those with weakened immune symptoms are at risk of developing more severe symptoms such as acute headache, high fever, stiff neck, nausea or vomiting, difficulty swallowing or confusion.
