West Nile Virus Found in Clarington Mosquitoes

The Durham Region Health Department has confirmed that mosquitoes in Clarington have tested positive for West Nile virus (WNV). This season, 11 mosquito batches in Durham Region have tested positive, including three in Clarington. The positive mosquitoes were collected from trap sites in Ajax, Clarington, and Pickering. The Health Department sets traps across the region and tests mosquitoes weekly from June to September.

WNV is spread to humans through the bite of an infected mosquito. Symptoms can range from mild, such as fever and headache, to severe, including muscle weakness and confusion. Symptoms typically appear between two and 15 days after being bitten.

To reduce the risk of mosquito bites and WNV infection, the Health Department advises residents to:

• Wear shoes, socks, and light-coloured clothing, including long sleeves and pants, especially at dusk or dawn.
• Use insect repellent containing DEET or Picaridin on exposed skin.
• Remove standing water from properties to prevent mosquito breeding.
• Ensure window and door screens are in good repair.

The Health Department treats regional catch basins and stagnant water sites with larvicide to reduce mosquito populations. For more information, visit durham.ca/WestNile.
