Huron Perth Public Health has confirmed that a second mosquito has tested positive for West Nile Virus in the area.
HPPH says the mosquito was caught in a trap in St. Marys a week after one was reported in Mitchell.
No human cases of West Nile have been reported in Ontario this year, and HPPH says not everyone who is bitten by an infected mosquito will show symptoms.
Those who do will experience mild illness including fever, headache, body aches, nausea, vomiting, and rash on the crest, back or stomach.
About 1-150 people will get seriously ill with symptoms like a high fever, muscle weakness, vision loss and a coma.
