Measles Outbreak in Manitoba: A Growing Concern
Manitoba is grappling with a concerning measles outbreak, recording the highest number of cases in Canada in 2026. This outbreak, which began in 2025, has put the province in a challenging position, with a surge in infections and a need for stronger public health messaging.
Dr. Davinder Singh, Manitoba's public health lead on measles, revealed that the province is experiencing its highest monthly case counts since May. The situation is alarming, as the reported cases are likely just the tip of the iceberg. Singh estimates that the actual number of infections could be 10 times higher than what is officially recorded.
But here's where it gets controversial: Despite the severity of the outbreak, many people remain susceptible to measles, especially in the Southern Health region. The virus is spreading rapidly, primarily in communities like Winkler and Morden, where vaccine uptake is lower than average.
The outbreak's impact is far-reaching. Many individuals cannot pinpoint their exposure to the virus, indicating widespread transmission. As a result, the province is intensifying its messaging, urging parents of infants aged six to 12 months to ensure their children receive an early vaccine dose. This proactive approach aims to protect the most vulnerable.
The reluctance to vaccinate stems from various factors, including concerns about safety and efficacy, as well as the misconception that measles is not a serious illness. This belief is particularly prevalent among a substantial group of people in the affected areas who remain skeptical of vaccination, even after the COVID-19 pandemic.
The recent surge in cases may be linked to holiday gatherings in December, as measles has an incubation period of 7 to 21 days. The initial cases in Manitoba were traced back to a household in a southern community, with exposure occurring during travel in Ontario.
The outbreak has disproportionately affected unvaccinated or under-vaccinated children, who make up the majority of cases. In 2026, Manitoba reported 51 confirmed and three probable cases up to January 24, a significant increase from the 2000-2024 period.
The outbreak has had severe consequences. Manitoba reported that 86% of cases involved unvaccinated individuals, with only 3% having received one vaccine dose. Tragically, 16 out of 22 hospitalized patients were under the age of 10, and one baby was born with congenital measles. Fortunately, no deaths have been reported.
In response, Manitoba expanded vaccine eligibility for children aged six months to one year in May 2025, and over 2,078 children in this age group have received their first dose. This proactive measure is a step in the right direction, but the challenge of vaccine hesitancy remains.
The true extent of the outbreak is difficult to ascertain, as many infected individuals may not seek medical attention. A Winkler physician, who wished to remain anonymous, confirmed that the actual number of infections is likely much higher than reported.
The outbreak has sparked a debate about the importance of vaccination. While some people are hesitant due to misinformation or distrust, public health officials and local leaders emphasize the safety and effectiveness of the measles vaccine. Winkler Mayor Henry Siemens encourages residents to consult healthcare professionals for accurate information.
To combat the outbreak, public health officials have taken proactive measures, including sending vaccine information to families and offering immunization clinics at schools. Religious leaders have also been engaged to spread awareness within their congregations.
As of January 24, 2026, Manitoba led the country in measles cases, with Alberta close behind. Canada's measles elimination status, achieved in 1998, has been lost, and the outbreak's origins can be traced back to a large gathering in New Brunswick in 2024.
The outbreak raises important questions about public health and individual responsibility. How can we ensure that accurate information about vaccines reaches everyone? What steps can be taken to address vaccine hesitancy and misinformation? These are crucial discussions that impact the well-being of our communities. Share your thoughts and let's explore these complex issues together.
