Global News : Plus de tiques et plus de maladies de Lyme dans l'avenir du Canada, selon les experts

Tick season has begun across much of Canada, bringing with it the threat of Lyme disease.

Just a few decades ago, Lyme disease was pretty well unheard-of in Canada. But climate change and other factors have facilitated a growing number of cases in the last few years.

“It’s spreading geographically, so there’s more of Canada affected,” said Nick Ogden, a research scientist and director of the public health risk sciences division with the National Microbiology Laboratory. “But behind that, the seasons are longer, the numbers of ticks are increasing and the proportion that are infected is increasing.”

There were 2,025 Lyme disease cases in Canada in 2017 – the latest year for which public data is available. This is a huge jump from the mere 144 cases reported in 2009.
