Public Health officials have received confirmation that an adult in Toronto has tested positive for West Nile Virus – the first such case for 2015.

Officials are investigating to determine where the unidentified adult acquired it as the person had potential exposures in and outside the city.

Symptoms usually develop anywhere from two to 15 days after someone’s bitten by an infected mosquito.

Last year, 10 positive mosquito pools and three human cases were reported.

So far this year, Toronto Public Health has received no reports of any positive mosquito pools.
