Point Edward, ON – Lambton Public Health’s surveillance program has confirmed mosquitoes collected on Wednesday, Aug. 16 from two traps, located in Wyoming and Sarnia, have tested positive for West Nile Virus.
These are the first positive results for the 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 two reported human cases of West Nile Virus as well as 114 positive mosquito pools across the province thus far 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.
