Canada's measles rate per capita surpasses U.S. as North American outbreak expands

World Health Organization data reveals that Canada has surpassed the United States in measles cases per capita, recording 1,107 cases compared to the U.S. total of 2,260, despite having one-tenth of the population. The broader Americas region is experiencing its worst outbreak in over two decades, with 47,459 cases and 45 deaths. While Manitoba's cases are declining from their February peak, the U.S. faces a critical review that could strip its long-held measles elimination status.

North American outbreak expansion

• ▪Approximately 186,000 measles cases were reported globally as of July 2026, representing a 12 percent increase compared to the same period in 2025.

• ▪An ongoing measles outbreak in Utah has lasted for more than 12 months, which is the primary criterion for losing measles elimination status.
• ▪The United States is at risk of losing its measles elimination status, held since 2000, after logging consecutive years with more than 2,200 cases.
• ▪A Centers for Disease Control and Prevention committee will review measles data in August 2026 to determine if the United States has lost its elimination status.
