West Nile Virus Positive Mosquitos Found in Peel

BRAMPTON, ON (August 2, 2018) – West Nile virus has once again been detected in mosquitos collected in the Region of Peel. So far this summer, three mosquito pools have tested positive for the virus. The Region reminds residents that it is not uncommon to find West Nile virus in local mosquitos.

West Nile virus became established across much of North America in the late 1990s and public health units, including Region of Peel – Public Health, have run annual programs to help monitor and control the population of mosquitos that carry the virus.

“Public Health maintains and monitors 33 mosquito traps that are set up across the cities of Mississauga and Brampton and the Town of Caledon. These traps are tested weekly from June to September and with this recent confirmation of West Nile virus activity, we are increasing our efforts in the area surrounding the positive traps by looking for breeding sites and re-treating catch basins with larvicide,” says Paul Callanan, Director of Health Protection at the Region of Peel.

The Region of Peel encourages residents to take extra precautions during dusk and dawn when mosquito activity is higher. Wear light coloured, long sleeved shirts and pants and use mosquito repellent containing DEET if older than six months of age. Children under six months can be protected with insect netting.

“Luckily, the summer to this point hasn’t been extremely wet, which has limited prime breeding conditions for mosquitos, added Callanan. “However, this can change from week to week and we urge people to protect themselves and do their part to reduce the spread of mosquito populations in their neighbourhoods and communities by removing standing water.”
