Wellington-Dufferin-Guelph Public Health has issued updated guidelines regarding tick encounters, suggesting that tick checks should be conducted after any outdoor activity when temperatures exceed 0 degrees Celsius. According to Phil Wong, the health unit’s health protection operations director, a surveillance program revealed an increase in tick sightings beyond wooded areas to include parks, trails, private properties, and occupational settings. Wong highlighted that individuals are discovering ticks not just in long grassy areas but also while gardening or raking leaves at home. While the risk of ticks on playgrounds is low, parents are advised to inspect their children for ticks after outdoor play.
As the local tick population grows, Canadians are advised to brace for an influx of ticks from the U.S. Health Canada reports over 40 tick species in Canada, some native while others introduced through hosts like birds and deer. Certain ticks, such as the Western blacklegged tick, can transmit diseases like Lyme disease, while the lone star tick may trigger meat allergies in humans. To address the escalating tick presence, the Canadian Tick Research and Innovation Centre was recently inaugurated at Acadia University, alongside the G Magnotta Lyme Disease Research Lab at the University of Guelph.
Justin Wood, CEO of Geneticks and a Lyme disease researcher, stressed the importance of early detection and intervention for tick-borne illnesses. Despite common hopes for tick reduction during cold winters, Wood explained that ticks typically survive in leaf litter through insulation. He emphasized the need for continuous tick monitoring and reporting through online platforms provided by public health agencies. Wong encouraged outdoor activities but underscored the necessity of post-outdoor tick checks to mitigate risks effectively.
