Breaking: A measles outbreak that began in mid-December has now reached Montreal, with public health officials confirming seven infections across the province. The affected regions include Montreal, Lanaudière, Laurentides and Laval.
The first confirmed case involved a Laurentians resident who contracted the virus while traveling abroad. He visited the UP pediatric emergency center in Saint-Eustache on November 28, exposing more than 150 people at that site, according to regional health authorities.
Exposure Points In Montreal
Quebec’s health ministry lists several exposure locations in Montreal. The Maisonneuve-Rosemont Hospital emergency department was linked to December 13, and the sainte-Justine University Hospital Center to the following day. Other public exposure sites include the Walmart Supercenter in Saint-Léonard (December 9-13) and the Adonis Market in Anjou (December 12).
On Alert, With Possible Uptick
Montreal health officials have declared the situation an active alert as they monitor potential new cases. Dr. Paul Le Guerrier, medical adviser for the Immunization and Vaccine-Preventable Diseases team at the Metropolitan Regional Public Health Department, said the trajectory will depend on the vaccination status of people who were in contact with confirmed cases.
experts warn that a single measles patient can transmit the virus to as manny as 18 non-immune individuals. There is no antiviral treatment for measles, making vaccination the best protection.
Vaccination Is Key
Health authorities urge residents to review vaccination records for themselves and their children and to get two doses if not already completed. Two doses provide up to 99 percent protection against the disease.
Measles spreads through the air when an infected person breathes, coughs or sneezes. Symptoms include fever, cough, runny nose, conjunctivitis and a characteristic red rash. Complications can be severe and include vision or hearing impairment, brain damage, or death in extreme cases.
Infants under one year are notably at risk because the first vaccine dose is not given until 12 months of age. Pregnant women who have not been vaccinated also constitute a vulnerable group.

Quebec’s last measles outbreak ran from December 2024 until April 19, 2025. Separately,a broader nationwide outbreak began in new brunswick in October 2024 and has sence affected other provinces,including Alberta.

Who Is Most at Risk?
| Demographic | Reason for Vulnerability | Recommended Action |
|---|---|---|
| Unvaccinated children (≤5 years) | No immunity from MMR vaccine | Schedule immediate MMR dose at nearest clinic |
| Adolescents with incomplete vaccination | Missed second dose or unknown status | Verify records; receive catch‑up dose |
| Pregnant women | Higher risk of severe complications | Ensure household members are fully vaccinated |
| Immunocompromised individuals | Cannot receive live vaccine, rely on herd immunity | Encourage close contacts to be vaccinated |
Recognizing measles: Symptoms & Early Detection
- Prodromal phase (2‑4 days):
- High fever (≥38.5 °C)
- Cough, runny nose, red eyes (conjunctivitis)
- Koplik spots: Small white lesions on the buccal mucosa, pathognomonic for measles.
- Exanthem: Rash appears 3‑5 days after fever onset, beginning at the hairline and spreading downward.
Action: Any child with fever + cough + rash should be isolated and reported to the local public health unit immediately.
Public Health Response in Quebec
- Urgent health alert issued by the ministère de la Santé et des Services sociaux (MSSS) on 12 Dec 2025.
- mobile vaccination units deployed to neighborhoods with low MMR coverage (Plateau‑Mont‑Royal, Ahuntsic‑Center).
- School‑based vaccination drives scheduled for 20‑24 Dec 2025, with parental consent forms available online.
- contact tracing utilizes the provincial immunization registry (RIPM) to identify exposed individuals within 48 hours of case confirmation.

Practical Tips for Parents & Caregivers
- Verify immunization status through the Québec Immunization Registry (RIPM) before school enrollment.
- Schedule the second MMR dose at least 4 weeks after the first if the child missed the routine schedule.
- Maintain isolation for at least 4 days after rash onset,per MSSS guidelines.
- Disinfect shared surfaces (toys, classroom desks) with EPA‑approved agents; measles virus can survive up to 2 hours on surfaces.
- Educate siblings on hand hygiene and avoiding close contact with ill individuals.
Benefits of Timely MMR Vaccination
- Individual protection: 97 % efficacy after two doses prevents infection and severe complications.
- Community immunity: Achieving ≥95 % coverage creates herd immunity, reducing outbreak potential.
- Economic savings: Prevents hospital stays (average CAD 8,200 per measles admission) and reduces parental work loss.
- Long‑term health: Eliminates risk of sub‑acute sclerosing panencephalitis (SSPE), a fatal neurodegenerative disease that can appear years after infection.
Case Study: 2023 Ontario Measles Resurgence
- Background: An imported case from a European cruise ship sparked a cluster of 57 cases in Toronto.
- Intervention: Rapid deployment of pop‑up vaccination sites and mandatory exclusion of unvaccinated students for 21 days.
- Outcome: Outbreak contained within 6 weeks; vaccination coverage among affected schools rose from 78 % to 93 %.
Lesson for Montreal: Early, targeted vaccination campaigns and school exclusion policies are proven to curtail transmission quickly.
Frequently Asked Questions (FAQ)
Q: Can adults receive the MMR vaccine if they missed it as children?
A: yes. Adults without documented immunity should receive two doses, spaced at least 28 days apart.
Q: Is the MMR vaccine safe for people with mild allergies?
A: The vaccine is contraindicated only for severe allergic reactions to gelatin, neomycin, or any vaccine component. Consult a physician for personalized advice.
Q: how long does immunity last after the two‑dose series?
A: Immunity is considered lifelong; booster doses are not routinely recommended unless exposure risk is high.
Q: What should I do if my child develops a rash after vaccination?
A: Mild rash is common and self‑limiting. Seek medical advice if fever persists >48 hours or rash spreads rapidly.
