Canada has reported over 4,500 measles cases in 2025, marking the highest count in the Americas this year. Ontario alone accounts for 2,363 confirmed or probable cases. This surge contributes to what commentators describe as “the year of measles in North America,” with the United States also experiencing its highest number of measles cases in more than three decades. According to World Health Organization data, Canada represents about half of all confirmed measles cases in the Americas region in 2025. Meanwhile, Mexico is facing measles outbreaks among unvaccinated communities, exacerbated by significant healthcare budget cuts. In the state of Hidalgo, Mexico, measles vaccination coverage is only around 72%, prompting the local Health Council to declare a permanent preventive alert. Over 75% of Hidalgo’s territory is considered at risk for measles contagion due to low vaccination rates.
