Measles Outbreak Declared Over in Canada After Two Years
20 Oct
Summary
- Canada's 2-year measles outbreak, infecting over 6,400, is officially over.
- Two infants died after contracting measles in the womb.
- Declining vaccination rates and pandemic disruptions fueled the outbreak.
The Public Health Agency of Canada announced on Monday, October 19, 2026, that a pervasive measles outbreak has concluded. This outbreak, which began in October 2024 in New Brunswick, spanned two years and infected over 6,400 individuals across all 10 Canadian provinces. The prolonged transmission led to Canada losing its measles elimination status for more than 12 months.
Tragically, two infants succumbed to the illness after contracting measles while in the womb, one in Ontario and another in Alberta. Experts attribute the resurgence of measles to a combination of factors, including decreased vaccination rates, hesitancy fueled by misinformation, and the impact of COVID-19 pandemic disruptions on routine immunizations.
While the declaration brings relief, Chief Public Health Officer Dr. Joss Reimer emphasized that measles is not eradicated. Global circulation means further travel-related cases are anticipated. Provinces like Ontario and Alberta had previously declared their respective outbreaks over in the fall of the previous year and in July, respectively. Manitoba reported its last confirmed case in August.
