Mosquito Pool Tests Positive for West Nile Virus

Point Edward, ON – Lambton Public Health’s West Nile virus (WNV) surveillance program confirms mosquitoes collected from a trap located in Petrolia on August 28th have tested positive for the virus.

This is the first positive result for the virus in Lambton County this year. There have been no positive human cases of WNV in Lambton County, but 2 human cases have been confirmed in Ontario at the time of this release.

Lambton Public Health continues to monitor for the virus. Weekly mosquito samples are collected throughout Lambton. Dead bird reporting and testing also continues.

Dr. Sudit Ranade, Lambton Medical Officer of Health, reminds residents that West Nile is present in Lambton County and recommends residents take precautions to prevent exposure to mosquitoes and to eliminate mosquito breeding sites on their property.

West Nile virus is spread to humans through the bite of an infected mosquito. The majority of people infected with West Nile virus do not get sick. Those who do become ill usually experience mild flu-like symptoms such as fever, headache, skin rash or muscle aches. Less than 1% of people infected with the virus get seriously ill.

To reduce your risk of being bitten by mosquitoes:

  • Avoid areas with high mosquito populations.
  • Take extra precautions from dusk to dawn when mosquito activity is high.
  • Wear protective, light-coloured clothing.
  • Use repellents containing DEET. Follow label instructions carefully.

To reduce mosquito breeding areas:

  • Drain areas of standing or stagnant water on your property.
  • Remove old tires; turn over pails, toys and wheelbarrows.
  • Change water in bird baths (at least weekly).
  • Keep eaves clear to avoid trapped water.
