Quebec Announces Measles Outbreak Officially Over After 32 Days Without Reported Cases

Quebec’s Health Department has declared an end to the measles outbreak in the province.

A spokeswoman said today the department determined the outbreak was over after no new cases were reported over the weekend.

Marie-Christine Patry says an outbreak can be considered over if 32 days pass without a new reported infection.

Quebec’s outbreak began in December 2024, and involved a contagious traveller who had visited the province before they were diagnosed.

Most of the province’s cases—32 out of 40—were reported in the Laurentians region north of Montreal.

The federal government says there have been 880 measles cases reported in five provinces so far in 2025, with the vast majority—804—in Ontario.

Patry says there hasn’t been a new case of measles reported in Quebec since March 18.
