## Key points

- The US, Mexico and Guatemala could lose measles elimination status.
- The review looks for 12 months of uninterrupted spread of one strain.
- PAHO recorded 57,666 cases across 17 places by October 2026.

## Summary

Health experts are reviewing whether the United States, Mexico and Guatemala should lose their measles elimination status, as prolonged outbreaks raise concern that the virus is spreading locally. The designation means a country has had no uninterrupted domestic transmission of the same measles strain for at least 12 months; losing it would mark a reversal of a major public-health achievement.

The Pan American Health Organization’s independent commission is assessing data from 2025 and the first half of 2026, including genetic sequencing, vaccination coverage, surveillance and outbreak responses. PAHO recorded 57,666 confirmed cases across 17 countries and territories from January to October 2026; Canada lost its status last November, and Peru and Bolivia are also at risk. The commission will recommend decisions to PAHO’s director, with an announcement expected early next week.
