Lambton Public Health has found mosquitoes carrying West Nile Virus in both Wyoming and Sarnia.
Officials say the data collected Aug. 16 are resulted in the first positive cases of the virus in Lambton this year.
There have been no human cases of the virus yet. Public Health Ontario says there have been two West Nile Virus cases reported in humans so far this year.
Most people infected after being bitten by a mosquito with West Nile Virus do not get sick. Those who do usually have mild flu-like symptoms such as fever, headache, skin rash, or muscle aches.
Less than one percent of people infected become seriously ill.
Public health says to avoid being bit, use bug spray with DEET, wear long sleeves and pants and to keep mosquitoes from breeding at your home, remove as much standing water as possible.
