A new measles outbreak has been confirmed at a pediatric center in saint-Eustache, Quebec, adding to a growing national concern as Canada battles a resurgence of the highly contagious disease. The nation lost it’s measles elimination status in November, a milestone achieved in 1998, and has already recorded over 5,000 cases in 2024 and 2025 [[3]], including tragic fatalities among infants [[1]]. Health officials are urging vigilance, especially for vulnerable populations, as outbreaks persist in multiple provinces despite Ontario declaring its outbreak over in October.
A recent outbreak of measles has been identified at a pediatric center in Saint-Eustache, Quebec, marking a resurgence of the highly contagious disease after a period of relative calm in the region. Public health officials have currently confirmed three cases linked to the center.
Measles is characterized by a high fever, cough, runny nose, red eyes, and a rash that begins on the face and spreads throughout the body. The disease poses a significant risk, particularly to vulnerable individuals like unvaccinated infants, and can lead to serious complications and, in some cases, even death. This outbreak underscores the importance of maintaining high vaccination rates to protect community health.
The outbreak was reported at the UP pediatric emergency center in Saint-Eustache. Individuals who visited the facility between 3:30 PM and 8:10 PM on November 28th may have been exposed to the virus and are advised to monitor for symptoms until December 19th.
According to public health guidelines, individuals who are not vaccinated and have been in contact with a confirmed case of measles should isolate themselves at home from the 5th day following exposure through the 14th day, inclusive. It’s important to note that individuals are not contagious during the first four days after exposure.
Loss of Elimination Status
Canada lost its measles elimination status in November, a designation it had held since 1998. This development highlights the challenges of maintaining disease control in the face of declining vaccination rates and increased global travel.
The current measles epidemic in Canada began in New Brunswick in October 2024 and has since affected over 5,000 people nationwide, tragically resulting in the deaths of two infants in Alberta and Ontario.
Ontario, which was considered the epicenter of the outbreak for several months, declared its outbreak over in October after recording more than 2,000 cases. Quebec’s outbreak concluded in April, with a total of 36 reported cases.
An outbreak of the same measles strain continues in Alberta, where approximately 2,000 people have contracted the disease. Several other provinces are also reporting sporadic cases.
Canada can regain its measles elimination status once the transmission of the outbreak-associated strain is interrupted for at least 12 months. This requires sustained vaccination efforts and robust public health surveillance.
