As of November 5, no case of Lyme disease had been reported for the current year in Saguenay / Lac-Saint-Jean, on the northern coast, nor in the Nord-du-Québec, Nunavik and James Bay regions.
Lyme disease is infectious and can cause skin, neurological, joint, cardiac and ocular manifestations. The bacterium is transmitted to humans through the bite of an infected tick.
Authorities report that cases of Lyme disease are usually acquired during a bite of a tick in the pup, which is more active during the spring and summer months. But adult ticks, which are about the same size as a sesame seed, are more active during the fall. They can also be active in winter in mild weather and when there is not much snow.
