The recent decline in measles cases in Manitoba marks a temporary lull in the outbreak. Health experts caution that the province is still far from achieving herd immunity, indicating a potential resurgence of cases in the future. Dr. Davinder Singh, Manitoba’s medical officer of health for immunization, highlighted the need for improved vaccine uptake to prevent further outbreaks.
After reporting two confirmed measles cases in July, infections reached their lowest level since March 2025. Manitoba experienced a 3½-week period in July with no new reported cases, the longest since the winter of 2024-25. While transmission persists, the rate has significantly decreased compared to the previous winter peak of 177 cases in February.
The number of measles cases has steadily decreased since then, dropping to 49 cases in May and eight in June. Dr. Singh anticipates a potential increase in cases during the fall but believes it will be substantially lower than previous peaks. Brandon Mayor Jeff Fawcett noted the significant reduction in measles cases, with the disease no longer a prominent concern as large events are held in the city.
Despite the recent downturn in cases, Dr. Philippe Lagacé-Wiens, a medical microbiologist, emphasized that measles remains a seasonal virus with higher transmission rates during colder months. He warned that without achieving herd immunity, there is a risk of another increase in cases in the future.
Experts indicate that at least 95% of Manitoba’s population needs immunity to halt measles transmission. However, current data shows vaccination rates are below the target, with only about 72% of children receiving two vaccine doses by age seven. Dr. Singh stressed the importance of increasing vaccination rates to prevent future outbreaks and protect vulnerable individuals.
Efforts to combat measles in Manitoba include expanding vaccine eligibility to infants as young as six months old and providing accurate information about immunization through various channels. Health officials continue to work on building trust in immunization to raise vaccination rates in the province and prevent future measles outbreaks.
