As March Break approaches, the Simcoe Muskoka District Health Unit (SMDHU) is urging residents to ensure their vaccinations are up to date, particularly against measles, mumps, and rubella (MMR). With increasing measles activity both internationally and within Canada, health officials are emphasizing the importance of immunization to protect individuals and prevent outbreaks within the community.
The call to action comes as travel plans are finalized and gatherings are planned. Protecting against measles is especially critical now, as the virus is experiencing a resurgence globally. Even a single case can quickly lead to outbreaks, impacting schools, workplaces, and communities. The highly effective MMR vaccine, providing approximately 97% protection after two doses, remains a cornerstone of preventative public health measures.
“Make sure your March break souvenir isn’t measles,” the Simcoe Muskoka District Health Unit stated in a recent public service announcement. This message underscores the potential risk of contracting the virus while travelling and bringing it back to the region.
Measles Cases Rising in Canada and Beyond
As of February 16, 2026, Health Canada reported a total of 192 measles cases this year across Alberta, Manitoba, Quebec, and Ontario according to York Region. Outbreaks are currently being reported in several countries, including Mexico and the United States, increasing the risk for those travelling internationally. The SMDHU recommends ensuring immunizations are current, including two doses of the MMR vaccine by age five, before travelling.
The measles vaccine is safe and highly effective, providing about 97 percent protection after two doses. In Ontario, children routinely receive the MMR vaccine at one year of age and again at four years as part of the province’s immunization schedule. Individuals who are not protected against measles and certain other communicable diseases may be excluded from child care, school, or work if an outbreak occurs in the community.
Who Should Get Vaccinated?
The health unit specifically recommends that the following groups prioritize updating their vaccinations:
- Children aged four to six years of age.
- Older children who may have missed their second dose of the MMR vaccine.
- Individuals born in 1970 or after who are planning to travel outside of Canada.
- Adults 18 years and older who are health care workers, post-secondary students, or have been advised by their health care provider.
Infants aged six to 11 months who will be travelling to areas with increased measles transmission, in consultation with their healthcare provider, can also receive an early first dose of the vaccine. Those born before 1970 are generally presumed immune due to prior circulation of the virus in Canada, but a single dose is recommended if they are travelling internationally and have never had measles or received the vaccine.
Understanding Measles and its Complications
Measles is a highly contagious viral infection that spreads through respiratory droplets when an infected person coughs or sneezes. The virus can remain infectious in the air for up to two hours. Symptoms typically begin seven to 21 days after exposure and include fever, runny nose, cough, irritability, red eyes, and small white spots inside the mouth. A characteristic red, blotchy rash then appears, starting on the face and spreading down the body.
While often mild, measles can lead to serious complications, including ear infections, pneumonia, diarrhea, and, in rare cases, encephalitis (swelling of the brain). These complications are particularly dangerous for young children.
Appointments for publicly funded vaccines are available by appointment only at all Simcoe Muskoka District Health Unit offices. Residents can contact their health care provider or book an appointment online at a health unit immunization clinic in Barrie, Collingwood, Cookstown, Gravenhurst, Huntsville, Midland, or Orillia.
As travel plans solidify and communities prepare for increased social interaction during March Break, prioritizing vaccination remains a crucial step in protecting individual and public health. Continued monitoring of measles activity and adherence to recommended immunization schedules will be essential in mitigating the risk of outbreaks in the coming months.
