Ticks Surveillance Data
Main Page Content
Active surveillance involves the dragging of a white cloth through grassy areas whereby ticks attach themselves to the cloth and can be easily spotted. Ticks collected on the cloth are sent to an accredited lab for testing. Tick dragging is performed twice yearly to identify areas in WEC that have populations of blacklegged ticks, which is the main vector for Lyme disease.
- In 2019, tick dragging was conducted at four sites (Chrysler Greenway, Ojibway Prarie Nature Reserve, Gesstwood Camp and Ruscome Shores Conservation Area) in the spring and in the fall.
- Two blacklegged ticks were found through tick dragging with none carrying the infectious agent of Lyme disease.
Residents submitted ticks to the WECHU for identification and subsequent testing if the tick is identified as a blacklegged tick.
- 329 ticks were submitted to the WECHU in 2019. Tick species were identified for 328 ticks (99.7%).
- 38 blacklegged ticks were identified to the WECHU (11.6% of identified ticks).
- Five blacklegged ticks tested positive for Borrelia burgdorferi, the bacteria that causes Lyme disease.
