Canada is likely to lose its measles elimination status. The U.S. could be next.

Main Idea: The Pan American Health Organization says Canada is likely to lose its measles elimination status after a year-long outbreak, and the United States could face the same risk later if spread continues.

Key Points:

• Canada’s outbreak began in October 2024 and has grown to more than 5,000 reported cases, with two baby deaths.
• Measles elimination status can be lost after 12 months of nonstop spread of the same virus strain.
• The United States has logged at least 1,618 measles cases this year, but officials say it is not yet likely to lose elimination status soon.
• Health experts say low vaccination rates are helping outbreaks spread, and the MMR vaccine is highly effective at preventing measles.
