Wellington-Dufferin-Guelph Public Health has issued new advice regarding tick encounters, suggesting that people conduct tick checks after being outdoors in temperatures above 0 C. The health unit’s director of operations for health protection, Phil Wong, mentioned that through a surveillance program involving photo submissions and information on tick encounters, they have observed ticks in various locations beyond wooded trails.
Wong identified three primary areas where people are encountering ticks: parks, trails, and camping sites with tall grass; private properties, including homes; and outdoor workplaces. He emphasized that individuals have reported finding ticks not only in long grass but also while gardening or raking leaves at home. However, he reassured parents that the risk of ticks on playgrounds, even those with wood chips, is low, but recommended checking children for ticks once they return indoors.
As the local tick population increases, Wellington-Dufferin-Guelph Public Health has updated its guidance. Experts anticipate a growing influx of ticks from the U.S. into Canada. Health Canada acknowledges over 40 tick species in the country, some native while others may arrive on hosts like birds and deer. Certain ticks can transmit diseases, such as the Western blacklegged tick, which can spread Lyme disease, and the lone star tick, known to cause meat allergies.
To enhance tick research and disease study, the Canadian Tick Research and Innovation Centre recently opened at Acadia University in Nova Scotia, complementing the G Magnotta Lyme Disease Research Lab at the University of Guelph. Justin Wood, founder of Geneticks, a tick testing company, emphasized the importance of early diagnosis and intervention for tick-borne illnesses. He highlighted the need for vigilance in conducting tick checks, as ticks often remain active during winter by sheltering in leaf litter.
The health unit encourages the public to report ticks online for tracking purposes and maintains a website for photo and information submissions. Despite the increasing tick risk, Wong advised against avoiding outdoor activities, emphasizing the enjoyment of nature while advocating for thorough tick checks upon returning home.
