As March Break approaches, families are gearing up for travel and gatherings, but health officials are urging a crucial step before departure: ensuring everyone is up-to-date on their measles, mumps, and rubella (MMR) vaccinations. The Simcoe Muskoka District Health Unit is emphasizing the importance of immunization, particularly given the increasing measles activity in popular travel destinations worldwide.
Protecting against measles is especially critical now, as the virus is experiencing a resurgence globally. The highly contagious nature of measles means that even a single case can quickly lead to outbreaks, impacting schools, workplaces, and communities. The MMR vaccine is remarkably effective, providing approximately 97% protection after two doses, and is 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 whereas travelling and bringing it back to the region. Ontario’s routine immunization schedule includes MMR vaccines at one year and four years of age, but ensuring continued protection requires awareness and, in some cases, booster doses.
The rising incidence of measles isn’t limited to distant locations. 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. This, coupled with outbreaks in the United States and Mexico, highlights the need for vigilance.
Where is Measles Spreading?
Outbreaks are currently being reported in several countries, including Mexico and the United States. In Mexico, as of February 16, 2026, there have been 3,418 confirmed cases of measles, with 1,995 of those cases concentrated in the state of Jalisco as reported by York Region. Tragically, there have been four measles-related deaths in Mexico this year, and 31 since the beginning of 2025. The United States Centers for Disease Control and Prevention (CDC) has reported 910 confirmed cases in the U.S. So far in 2026, with 90% of these linked to outbreaks as reported by York Region. Specifically, Florida and South Carolina are experiencing significant outbreaks, with 63 and 616 cases respectively.
Who Should Get Vaccinated?
The Simcoe Muskoka District Health Unit recommends that certain groups prioritize updating their MMR vaccinations before travelling. This includes:
- Children aged four to six years.
- Older children who may have missed their second dose of the MMR vaccine.
- Individuals born in 1970 or later who are planning international travel.
- Adults 18 years and older, particularly healthcare workers and post-secondary students.
Infants aged six to 11 months travelling to areas with increased measles transmission may as well benefit from an early first dose, in consultation with their healthcare provider. Those born before 1970 are generally considered immune due to widespread measles circulation at that time, but a dose is recommended if travelling internationally and unvaccinated.
Understanding Measles and its Risks
Measles is a highly contagious viral infection that spreads through respiratory droplets produced by coughing or sneezing. The virus can remain airborne for up to two hours, making transmission easy. Symptoms typically appear 7-21 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 develops, starting on the face and spreading throughout the body.
While often mild, measles can lead to serious complications, including ear infections, pneumonia, diarrhea, and, in rare cases, encephalitis (brain swelling). These complications are particularly dangerous for young children.
The Simcoe Muskoka District Health Unit offers MMR vaccinations at clinics in Barrie, Collingwood, Cookstown, Gravenhurst, Huntsville, Midland, and Orillia. Individuals can also contact their healthcare provider to schedule an appointment.
As travel plans solidify for March Break, prioritizing MMR vaccinations is a proactive step to protect both individual health and the broader community. Continued monitoring of measles cases globally and within Canada will be crucial in the coming months, and public health officials will likely adjust recommendations as the situation evolves.
