Mosquitoes test positive for West Nile Virus
Toronto Public Health received laboratory reports today indicating that mosquitoes in Toronto have tested positive for West Nile Virus (WNV). This is the first WNV positive result for Toronto this year. Both Windsor and Peel Region have also found mosquitoes with the virus.

“The positive test result is a good reminder for the public to protect themselves from mosquito bites, and to reduce mosquito breeding grounds by draining standing water around your home,” said Dan Kartzalis, Manager of the West Nile Virus program for TPH.

Toronto Public Health has 43 mosquito traps throughout the city and sends mosquitoes for laboratory testing every week. Larvicides are also used in catch basins throughout the city to reduce the mosquito population.

Although the risk of becoming infected with WNV is low, the virus can lead to serious illness. The last human case of WNV in Toronto was in 2007. Prevention against bites is the best protection. The following 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.
