Make sure you don’t catch Lyme disease

Lyme disease is caused by the Borrelia burgdorferi bacterium, and is transmitted to humans through the bite of infected blacklegged ticks, also called deer ticks. This tick lives in wooded areas, forests, tall grass, and shrubs. Actual climate change is enabling ticks to settle down in Québec, particularly in Montérégie and Es-trie. Lyme disease is also well established in other Canadian provinces, in the United States, Europe, and Asia.
