Manitoba Measles Outbreak: Cases Surge to 248 – Latest Updates

Manitoba is experiencing a significant surge in measles cases, with February recording 170 confirmed infections – a figure that marks the first time the province has seen monthly case numbers reach three digits. This escalating outbreak, following Canada’s loss of measles-free status in November 2025, is prompting increased public health vigilance and preventative measures, particularly for infants.

Rising Cases and Vulnerable Populations

The dramatic increase in measles cases in Manitoba is a stark contrast to previous years. From January 2000 to December 2024, the province reported a total of just 18 cases. As of March 9, 2026, Manitoba now has the highest number of measles cases across Canada. The current outbreak is particularly concerning for young children, with 18 of the 30 hospitalizations due to measles complications occurring in individuals under the age of 10. This underscores the vulnerability of unvaccinated children to severe illness. Measles is a highly contagious respiratory virus characterized by a full-body red rash, high fever, cough, and watery eyes.

Public health officials are actively investigating potential exposure sites, updating the public with information on locations and times where individuals may have been exposed. Recent exposure locations include flights – specifically Porter Airlines flight PD291 from Ottawa to Winnipeg on February 9, 2026, and Delta Air Lines flight DAL1912 from Belize City to Minneapolis on February 7, 2026 – as well as community locations like the Altona Sommerfeld Mennonite Church and Baldur School. The Manitoba government website provides a continually updated list of exposure locations and monitoring guidance.

Preventative Measures for Infants

In response to the outbreak, Manitoba health officials are proactively offering preventative treatment to infants who may have been exposed to the virus. This treatment, typically involving an injection of immunoglobulin, provides temporary protection against measles. CBC News reports that babies are receiving this preventative treatment on a weekly basis, highlighting the seriousness of the situation and the commitment to protecting the most vulnerable.

Vaccination Status and Case Data

Data released by the province reveals a strong correlation between vaccination status and infection rates. According to provincial data, 84.1% of confirmed cases to date involve individuals with no doses of the measles vaccine. Another 5.1% had received only a single dose, while 6.2% had two or more doses. This data reinforces the importance of vaccination as a primary means of protection against measles. It’s key to note that vaccination doesn’t guarantee 100% immunity, but it significantly reduces the risk of infection and severe complications.

Understanding Measles and its Spread

Measles is caused by a virus that spreads through the air when an infected person coughs or sneezes. This proves so contagious that if one person has measles, 90% of those who are not immune will turn into infected. The virus can remain infectious in the air or on surfaces for up to two hours after an infected person has left the area, which is why public health investigations include a buffer period around identified exposure locations. The Centers for Disease Control and Prevention (CDC) provides comprehensive information on measles, including symptoms, prevention, and treatment.

The Broader Context of Measles Resurgence

The situation in Manitoba is part of a broader global trend of increasing measles cases. The World Health Organization (WHO) has expressed concern about rising measles rates worldwide, attributing the increase to declining vaccination coverage. Factors contributing to this decline include vaccine hesitancy, disruptions to immunization programs due to conflicts and natural disasters, and gaps in healthcare access. Canada lost its measles-free status in November 2025, as reported by CTV News, signaling a concerning shift in the country’s disease control landscape.

What to Expect Moving Forward

Public health surveillance will continue to play a crucial role in monitoring the spread of measles in Manitoba. This involves tracking new cases, identifying exposure locations, and providing guidance to the public. Health officials will also continue to emphasize the importance of vaccination and offer preventative treatment to those at risk. The province will likely review its immunization strategies and explore ways to improve vaccination rates, particularly among vulnerable populations. Individuals are encouraged to stay informed about the latest updates from Manitoba Health and to consult with a healthcare professional if they have concerns about measles or their vaccination status.
