Mosquito tests positive for West Nile virus
Toronto Public Health reported today that a mosquito found in the city has tested positive for West Nile virus (WNV). This is the first WNV positive result this year. So far, no human cases of WNV have been reported this summer in Toronto, and no birds have tested positive for WNV.

“The positive mosquito result reinforces the need for the public to take precautions to safeguard themselves from West Nile virus,” said Dr. Howard Shapiro, Toronto Associate Medical Officer of Health. “Although the overall risk of becoming infected with WNV is low, anyone can get sick from WNV and the risk of severe illness increases with age. People with compromised immune systems due to illnesses or immune suppressing treatments are also at higher risk of severe illness from WNV.”

The risk of becoming infected starts around this time of year, peaks in August and continues into September. The following protective measures are recommended:

~Use mosquito repellent approved by Health Canada
~Wear light-coloured clothing and cover up when in areas where mosquitoes are present
~Take extra precautions, especially in early morning and early evening, when mosquitoes are most active
~Remove standing water around your home and property to reduce mosquito breeding sites.
