Mosquitoes test positive for West Nile Virus

Niagara Region Public Health is informing residents that Niagara has received its first confirmation of West Nile Virus (WNV) in mosquitoes in 2019. To date, in the Niagara region no human cases have been reported to Public Health.
While the mosquitoes that tested positive were found in St. Catharines, Welland, Port Colborne, and West Lincoln, all Niagara residents should take the necessary precautions to prevent West Nile Virus. To reduce the risk of being bitten by mosquitoes and potentially exposed to West Nile Virus, residents are reminded to:
  • Wear long-sleeved shirts, long pants, socks and shoes when outdoors 
  • Whenever you use mosquito repellent, apply a product containing DEET or Icaridin, and carefully read and follow the manufacturer’s directions
  • Drain any areas of standing or stagnant water on your property on a regular basis, including bird baths, old tires, pails, toys and wheelbarrows
  • Make sure all windows and doors in your home have screens that are in good condition
Residents with inquiries about West Nile Virus can call 905-688-8248 ext. 7590, or 1-888-505-6074. Further information about West Nile Virus and updates can be found online on the Niagara Region Public Health website.
