Three Birds Test Positive for West Nile Virus

Lab tests received today confirms three dead crows found in Grey Bruce carried the West Nile Virus (WNv). These are the first WNv positive birds in the region this year. There were two WNv positive birds in Grey Bruce in 2005.

The birds were discovered last week in the Walkerton and Ayton area. Surveillance for the virus has increased in these areas. The Health Unit submitted 24 birds for testing so far this summer. Monitoring dead birds is a predictor for the presence of WNv. In addition to dead bird testing, adult mosquito trapping, larval surveillance and human case surveillance is on going. There have been no positive mosquitoes or human cases of WNv identified in Grey Bruce this year. Residents are urged to continue to report dead birds to the Grey Bruce Health Unit.

The presence of the birds indicates WNv activity in the area according to West Nile Virus Surveillance program manager Susan Shular. “It is the time of year when people are the highest risk of becoming infected with West Nile Virus. I encourage residents and visitors to protect themselves against mosquito bites.”

 To reduce your risk of being bitten by mosquitoes:

·         Avoid areas with high mosquito populations

·         Take extra precautions from dusk to dawn when mosquito activity is high

·         Wear protective light-coloured clothing

·         Use repellents containing DEET (follow label instructions carefully)

·         Repair holes in screens, windows and doors to stop mosquitoes from getting into your home

·         Reduce the mosquito population around your property by eliminating standing water

Most people (80%) who are infected with West Nile Virus do not get sick. Those who do become ill usually experience symptoms consisting of fever, headache, muscle pain, and/or rash. Less than l% of people infected with the virus get seriously ill.
