Ticks and Lyme Disease for Healthcare Professionals


Tick Images

Under the Health Protection and Promotion Act all cases of Lyme disease are required to be reported to Public Health; including clinically diagnosed cases.  To report a case of Lyme disease to the Grey Bruce Health Unit, please call the Infectious Diseases Program at 519-376-9420.


Local Tick Surveillance

The Grey Bruce Health Unit operates a tick surveillance program in order to monitor trends in Lyme disease vector prevalence and thereby potential risks associated with locally acquired disease. Currently the program consists of passive surveillance for tick species of concern/interest based on ticks sourced from humans and from animals from participating veterinary clinics.

Healthcare Professionals can assist us with our local surveillance program by notifying us when you submit a tick to Public Health Ontario Lab (PHOL) and sharing with us the results. By providing this information you will be contributing to important local Lyme disease surveillance activities.


Note:  PHOL does not share tick identification results with GBHU when submitted by Healthcare professionals.
