Lyme Disease Risk In Quebec Most Significant In These Places

It's summertime and for some of us, that means long hikes through nature. Unfortunately, taking long hikes might also mean you could pick up a tick, some of which can transmit Lyme disease. 

Some Quebec municipalities are more high-risk for Lyme disease than others, according to information released by the Institut national de santé publique (INSPQ) in June.

How many Lyme disease cases were there in Quebec last year?

In 2020, there were 274 cases of Lyme disease reported to Quebec public health, 250 of which the INSPQ says were contracted within Quebec.

In 2019, there were 500 reported cases. The Institute says the drop may be due in part to delays in reporting and "a decrease in physician visits" during the pandemic, among other possible factors.

Estrie "remains the [region] the most affected by Lyme disease, reporting nearly 63% of all cases and a standardized incidence rate 10 times higher than the provincial rate," according to the INSPQ.

The Government of Quebec lists preventative measures online. They include staying on trails, covering skin with pants and long-sleeved shirts, and tucking "your pants into your socks or boots."
