Mosquitoes test positive for West Nile Virus

Point Edward, ON – Lambton Public Health’s surveillance program has confirmed mosquitoes
collected on Wednesday, Aug. 30, from a trap located in Forest, have tested positive for West
Nile Virus.

This is the fourth instance of mosquitoes testing positive for West Nile Virus in Lambton County
this year. No positive human cases of West Nile have been confirmed to date in the County.

According to Public Health Ontario, there have been five reported human cases of West Nile
Virus as well as 222 positive mosquito pools across the province in 2023.

West Nile Virus is spread to humans through the bite of an infected mosquito. Most 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. Fewer than one percent
of people infected with the virus become 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 repellants containing DEET or Icaridin. 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
