Overview

  • PAHO confirmed the region’s measles elimination certification was rescinded after the same viral strain circulated in Canada for at least 12 months.
  • As of Nov. 7, officials reported about 12,593 confirmed cases and 28 deaths across 10 countries, with roughly 95% of cases in Canada, Mexico and the United States.
  • Mexico continues an active outbreak with about 5,185 confirmed cases and 23 deaths, and PAHO is providing vaccine supply, laboratory surveillance and vaccinator training.
  • Approximately 89% of cases are in people who are unvaccinated or with unknown status, reflecting regional second‑dose coverage averaging about 79% in 2024—well below the 95% goal.
  • Cross‑border transmission has been documented in under‑vaccinated groups, including conservative Mennonite communities spanning Canada, Mexico and parts of the U.S.
