NEWMARKET - The Regional Municipality of York reports a mosquito pool has tested positive for West Nile virus (WNV). A pool is defined as one batch of mosquitoes caught overnight in one trap and sent for testing.
The mosquitoes were trapped in the Town of Newmarket, close to the intersection of Davis Drive and Prospect Street.
Ongoing treatment of catch basins will continue, as well as necessary treatment of surrounding stagnant water sources such as roadside ditches on public property. Trapping mosquitoes is part of the 2012 York Region WNV Control Plan and traps are set up at various locations throughout the Region.
Prevention and protection are the best ways to guard yourself and family from WNV. Clean up standing water around your home where mosquitoes are likely to breed, make sure screens on your home are tight-fitting and in good repair, cover up and use insect repellent when outdoors and minimize outdoor activities when mosquitoes are most active such as dusk and dawn.
The 2012 York Region WNV Control Plan includes:
- Mosquito and human surveillance to assess possible risk to human health
- Public education and outreach focusing on awareness, personal protection and reduction of mosquito breeding sites
- West Nile virus control activities, including larviciding to control the mosquito populations in target areas. Four larvicide applications take place over the summer months targeting all catch basins along Regional and municipal roads and in catch basins on private property, as required. Provincially authorized larvicides are low risk for humans, pets and the environment when applied correctly
- Case investigation of individual human cases to identify where a positive mosquito was encountered
Residents who are concerned about catch basins on private property are requested to place a mesh screen over the catch basin to prevent mosquitoes from entering and exiting. Backyard catch basins located on private property will be treated by request.
Symptoms of WNV illness may include fever, muscle weakness, stiff neck, confusion, severe headache and a sudden sensitivity to light. In rare cases, the virus can cause serious neurological illness, including encephalitis (inflammation of the brain). Those experiencing symptoms should seek medical attention.
