More Birds Positive for West Nile Virus – Bird Testing Ends

Latest results from laboratory testing confirm two more dead crows found in Grey Bruce carried the West Nile virus (WNv). This brings the total to eight WNv positive birds in the region this year. The birds were discovered last week in Proton Station and Dundalk.

With this latest find, the Grey Bruce Health Unit has reached the threshold for the maximum allowable number of birds submitted for testing by the Canadian Cooperative Wildlife Health Centre.  The presence of the infected birds confirms WNv activity in the region.  Public Health will continue to track sightings of dead crows, blue jays and ravens but will no longer accept carcasses for testing. Residents are urged to continue to report dead bird sightings.

Surveillance for the virus has increased in the areas where positive carcasses have been identified. Public Health submitted 29 birds for testing this summer. While dead bird testing has ended, adult mosquito trapping, larval surveillance and human case surveillance are on going. There have been no positive mosquitoes or human cases of WNv identified in Grey Bruce this year.

It should be noted mosquitoes remain active until first frost. At this time of year, there are increasing numbers of vectors; mosquitoes carrying the WNv. Residents are urged to continue to take precautions against 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.
