TheSimcoe Muskoka District Health Unit (SMDHU) is reminding residents to protect themselves against mosquito bites following confirmation that mosquitoes collected from a second trap in the City of Barrie tested positive for the West Nile virus (WNv). The first positive test was reported by the health unit on August 14.
WNv circulates between birds and some species of mosquitoes. The virus can be transmitted to humans by a mosquito bite, if the mosquito has first bitten an infected bird.
The risk of contracting WNv from an infected mosquito is highest in late summer. The health unit recommends the following personal protection measures:
- Use an approved mosquito repellent, and follow manufacturer’s instructions
- Wear light-coloured clothing and cover up arms and legs in areas where mosquitoes are present
- Try to stay indoors when mosquitoes are most active, especially at dusk and dawn
Although most people will not become sick if bitten by an infected mosquito, WNv can cause severe illness in some people. Symptoms of WNv include fever, muscle weakness, stiff neck, confusion, severe headache, and a sudden sensitivity to light. In very rare cases, the virus may cause serious neurological illness. Those experiencing symptoms should seek medical advice.
