Canada Now the Center of North American Measles Outbreak

CANADA, JUL 21 – Canada has reported 3,822 measles cases in 2025, nearly three times the U.S. total, with 86% of Canadian cases involving unvaccinated individuals, health officials said.

  • Canada is experiencing a large measles outbreak in 2025 with over 3,800 cases reported this year, primarily in Alberta and Ontario.
  • The outbreak began at a New Brunswick wedding with the initial case contracted outside North America amid declining vaccination rates since the pandemic.
  • The spread mainly involves unvaccinated individuals, including cultural groups wary of government, and infants aged six to twelve months are now eligible for earlier vaccination.
  • As of July 15, the U.S. reported 1,309 measles cases with three deaths, while health officials urge vigilance and cite Canada’s case number as nearly triple the U.S.'s despite a smaller population.
  • The outbreak poses a risk to the eradication status of both countries and has prompted increased vaccination efforts, home visits, and pop-up clinics to control spread.
