York Region Active Tick Surveillance Program

York Region Public Health conducts tick surveillance to determine the level of establishment of blacklegged tick (Ixodes scapularis) populations within an area; and to assess the possible risk of Lyme disease infection to humans.

Tick surveillance can be active by collecting ticks from their natural habitat, or it can be passive through examining ticks brought into Health Unit offices by members of the public. While quite different in their objectives, both modes are useful tools in determining the level of community risk from Lyme disease.
