As per reports, the Manitoba Public Health Department has confirmed a sustained and accelerating surge in measles cases across Manitoba Province, with monthly case numbers exceeding 100 for the first time since the outbreak commenced in February 2025, making Manitoba the national epicentre of measles transmission in Canada as of Tuesday (10 March).

• Provincial data current to 28 February 2026 confirm 248 confirmed and 36 probable measles cases recorded in Manitoba in January and February alone, a figure that already surpasses two-thirds of the 319 confirmed cases recorded across the entirety of 2025, reflecting a marked acceleration in transmission velocity into 2026.
• In epidemiological week 10 (02 March to 08 March), Canada’s federal measles and rubella surveillance system recorded 123 new measles cases nationally, with Manitoba accounting for the substantial majority, confirming that weekly case counts remain elevated and transmission is actively ongoing across the province.
• A significant transmission event has been identified at Manitoba Ag Days, held on 20 January in Brandon, attended by approximately 35,000 people, with more than 35 cases linked to the event and investigations ongoing across multiple provinces and the United States of America due to the event’s interprovincial and cross-border attendance profile.
• Of all reported cases since the outbreak began, 84.1 percent involved individuals who had received zero doses of the measles vaccine, 5.1 percent had received one dose, and 4.6 percent had an unknown vaccination status, with 31 individuals hospitalised, including three admitted to intensive care, and 19 of those hospitalised being children under 10 years of age.
• Manitoba Public Health has expanded eligibility for the measles, mumps, and rubella (MMR) vaccine to children aged six months to under 12 months in the Southern Health-Santé Sud, Interlake-Eastern, and Prairie Mountain Health regions in response to the intensifying outbreak, with the province relying on messaging, access improvement, and community trust-building rather than mandatory restrictions or large-event prohibitions.
• The affected areas include the Southern Health-Santé Sud region, with Winkler and Morden as primary epicentres, Brandon and the Prairie Mountain Health region, the Rural Municipalities of Stanley, Rhineland, Thompson, Dufferin, and Roland, Winnipeg, and the Interlake-Eastern region, with secondary case clusters identified in Ontario, Quebec, Alberta, and Saskatchewan at the national level.
