Mosquito

West Nile Virus (WNV)

West Nile virus is carried by mosquitoes that become infected by feeding on an infected bird. If an infected mosquito bites you, it can spread the disease onto you. Everyone in Ontario who spends time near infected mosquitos could get West Nile.[1]

The Grey Bruce Health Unit uses light traps to catch mosquitoes. The mosquitoes are sent to a lab for viral testing (e.g., WNV and EEEV).
