Innisfil crow tests positive for West Nile

A dead crow collected in Innisfil is the first bird to test positive for West Nile virus (WNv) in Simcoe Muskoka this season.

"This tells us that West Nile virus is the area and that we need to protect ourselves and our families throughout the season," says Marina Whelan, manager for health hazards at the Simcoe Muskoka District Health Unit. "The best way people can protect themselves against WNv is to avoid being bitten by mosquitoes by using insect repellent when they are outdoors and by covering up. It's also important that people get rid of any stagnant water around their home on a regular basis because that's where mosquitoes like to breed."

Since the health unit began its dead bird surveillance program in May it has received 186 reports of dead bird sightings. To date, three birds have been sent to the Canadian Cooperative Wildlife Health Centre in Guelph for testing.

"The public plays an important role in our West Nile virus program," Whelan said. "Reports of dead birds are critical in helping us identify those areas where risk appears to be higher."

West Nile virus is spread by the bite of mosquitoes that have previously bitten infected birds. People older than 50 and those with chronic disease or weakened immune systems are most at risk but anyone who lives in an area where there are infected mosquitoes can get WNv. The virus can cause serious illness in some people and, on rare occasions, death.
