Mosquitoes test positive for WNV in Oshawa

More adult mosquitoes have tested positive for West Nile Virus in Oshawa.

According to the Durham Region Health Department, the positive batch of mosquitoes was collected from one of the health department’s mosquito trap sites in Oshawa. The positive confirmation was received on Aug. 26.

The health department says these are the first mosquitoes in Oshawa to test positive for WNV this season. There have also been mosquitoes identified in WNV in Ajax this year.

With positive test results, the health department says it’s important for area residents to take precautions against WNV by avoiding mosquito bites and removing standing water from their properties.

Tips to minimize the risk of mosquito bites and the possibility of being infected with WNV include wearing shoes, socks and light-coloured clothing, long sleeves and full-length pants when outside, especially at dusk or dawn when mosquitoes are most active.

Insect repellent containing DEET or Picaridin on exposed skin will help repel insects.

Further, ensure that window and door screens are in good repair to prevent mosquitoes from entering the home.

The health department sets mosquito traps across the region and submits mosquitoes for lab testing every week between June and September.

Regional catch basins and other stagnant water sites are also treated with a larvicide to reduce mosquito breeding.
