Canada’s status as a country without endemic measles can now be revoked
- On Oct. 27, 2024, Canada reached a full year of continuous measles transmission, with more than 5,000 cases across 10 jurisdictions, including two infants in Ontario and Alberta who died.
- Public health experts from McMaster University say falling MMR coverage and COVID-19 pandemic disruptions caused 2-year-olds' vaccination to drop from nearly 90% in 2019 to less than 83% in 2023.
- Health data show all but 157 cases are outbreak-linked and about 90% occurred in unvaccinated people, while 30 new cases were reported in recent weeks despite slowed transmission.
- PAHO will review Canada's measles-elimination status in early November; WHO states loss occurs if transmission lasts over a year, requiring a corrective action plan with vaccination and surveillance.
- Regionally, six other countries including the U.S. and Mexico have active measles transmission, with the United States at risk of losing elimination status if cases continue into January; Venezuela and Brazil recently regained status after extensive efforts.
