Manitoba is experiencing a significant surge in measles cases, raising public health concerns as the province reports numbers far exceeding those seen in recent years. The increase, particularly pronounced in the first two months of 2026, underscores the importance of vaccination and ongoing monitoring efforts. The vast majority of those affected have not been fully vaccinated, highlighting vulnerabilities within the community.
As of February 27, 2026, Manitoba has recorded 215 confirmed cases and 22 probable cases of measles this year, according to provincial data. This represents a dramatic increase compared to the entirety of 2025, which saw 319 confirmed cases and 29 probable cases.
The early 2026 spike means more than two-thirds of all confirmed measles cases from last year have already been reported in January and February alone. Public health officials are closely monitoring the situation, particularly given the potential for severe complications from the highly contagious virus. Since February 2025, 12 cases have been identified in pregnant individuals, and one case of congenital measles has been reported, both of which are included in the overall totals.
Expanded Vaccine Eligibility
In response to the escalating outbreak, Manitoba Public Health has broadened eligibility for the measles, mumps, and rubella (MMR) vaccine. Children aged six months to under 12 months are now eligible to receive one dose of the MMR vaccine, in addition to the routinely scheduled doses at 12 months and between four and six years of age. This expansion aims to provide additional protection to vulnerable infants.
The expanded eligibility specifically targets families residing in Southern Health–Santé Sud, Interlake-Eastern, or Prairie Mountain Health regions. It also includes children who frequently travel to and have close contact with residents of these areas. This targeted approach acknowledges the regional concentration of cases and aims to curb further spread.
Hospitalizations and Impact
The impact of the measles outbreak is also being felt in Manitoba’s healthcare system. As of February 27, 2026, a total of 30 individuals have been hospitalized due to measles, with three requiring intensive care unit (ICU) admission. A concerning 18 of those hospitalized are children under the age of 10. Fortunately, no deaths have been reported to date.
Data from Manitoba Public Health reveal a strong correlation between vaccination status and infection rates. A significant 84.1 per cent of reported measles cases involved individuals who had received zero doses of the MMR vaccine. A further 5.1 per cent had received only one dose, while 6.2 per cent had received two or more doses, and the vaccination status of 4.6 per cent of cases remains unknown.
Ongoing Monitoring and Exposure Locations
Manitoba Public Health continues to actively monitor for new measles cases and potential exposures throughout the province, including those linked to travelers from other regions. Updated information on public exposure locations is regularly posted on the provincial website, allowing individuals to assess their risk and take appropriate precautions. National surveillance data is also available through the federal measles and rubella surveillance site.
Recent exposure locations identified by Manitoba Health include flights. Individuals who were on Porter Airlines flight PD291 from Ottawa to Winnipeg on February 9, 2026, are advised to monitor for symptoms until March 3, 2026. Similarly, passengers on Delta Air Lines flight DAL1912 from Belize City to Minneapolis on February 7, 2026, should monitor for symptoms until March 1, 2026. WestJet flight WS2451 from Puerto Vallarta to Winnipeg on February 4, 2026, also had a potential exposure, with passengers advised to monitor for symptoms until February 26, 2026. An exposure was also identified at Baldur School – Gym in Baldur, Manitoba on February 6, 2026, from 1:00 p.m. To 5:30 p.m.
Understanding Measles
Measles is a highly contagious disease characterized by a red, blotchy rash. The virus spreads through close personal contact with an infected person and through the air when an infected person coughs or sneezes. The virus can remain infectious in the air or on surfaces for up to two hours after an infected person has left the area, emphasizing the importance of prompt public health responses.
Case numbers are expected to fluctuate as investigations continue and more data becomes available. Manitoba Public Health encourages residents to stay informed about the outbreak and to consult with healthcare professionals if they have concerns about measles or vaccination.
