Residents planning summer hikes, camping trips, or outdoor activities in the Laurentides are being urged to take extra precautions following a significant expansion of areas considered at high risk for Lyme disease.
According to public health officials, nearly the entire Laurentides region is now classified as a high-risk zone for Lyme disease transmission, with only a handful of remote northern territories remaining outside the affected area.
The development highlights a growing public health challenge that is no longer confined to southern Quebec. Health authorities say Lyme disease has continued to spread into new regions over the past several years, a trend often associated with changing environmental conditions and expanding tick habitats.
For municipalities across the Laurentides, the announcement carries important implications. The region attracts thousands of visitors annually to its parks, forests, lakes, and recreational trails. As outdoor tourism remains a major component of the local economy, officials stress that residents and visitors should not avoid nature but instead adopt preventive measures.
Public health experts recommend staying on designated trails, avoiding tall grass, wearing long and light-coloured clothing, and using insect repellents containing DEET or icaridin. Individuals are also encouraged to perform tick checks after spending time outdoors and to shower promptly upon returning home.
One of the most important factors in preventing Lyme disease is the rapid removal of ticks. Health officials note that removing a tick within 24 hours significantly reduces the risk of infection.
The warning also has implications for local healthcare services. Residents who are bitten by a tick in a high-risk municipality may be eligible for preventive antibiotic treatment following an assessment by a physician or pharmacist.
The expansion of Lyme disease risk zones serves as a reminder that public health concerns increasingly intersect with environmental realities. As more residents embrace outdoor recreation, awareness and prevention are becoming essential tools in limiting the spread of tick-borne illnesses throughout Quebec.
