A measles outbreak in Quebec has risen to 27 cases, the majority of which are in the Quebec City area.
Health officials say the most recent case was reported on June 28.
Officials say 10 cases were reported last week in the Portneuf regional county municipality, west of the provincial capital.
Exposures sites include the emergency room at the St-Raymond hospital and at grocery stores and pharmacies in Pont-Rouge, Que., and Donnacona, Que.
Other cases have been reported since early June in Montreal, Laval, and in the Montérégie, Laurentians and Lanaudière regions.
Since 2024, Quebec has experienced three other measles outbreaks, the most recent of which started in November 2025 and ended in February 2026.
Measles is an extremely contagious disease and spreads through the air. On average, it takes 10 to 14 days from exposure to the virus until symptoms appear, which include a high fever, cough, runny nose, and red eyes. After, infected individuals will usually develop the characteristic measles rash on their face and body.
