Measles is making a comeback, and it's a global concern! The Simcoe Muskoka District Health Unit is urging residents to take action and protect themselves before the March break travel season.
But why the sudden alarm? Well, measles outbreaks are popping up worldwide, with several countries, including Mexico and the United States, currently battling the highly contagious virus. And as of February 16, 2026, Health Canada has reported a concerning number of cases in Alberta, Manitoba, Quebec, and Ontario.
Here's the deal: Measles is a serious respiratory disease that can lead to severe complications, especially in young children. It's easily spread through coughing and sneezing, and the virus can linger in the air for up to two hours! That's why the health unit is emphasizing the importance of the MMR (Measles, Mumps, and Rubella) vaccine.
The MMR vaccine is a powerful shield, offering approximately 97% protection after two doses. In Ontario, children receive their first dose at one year old and the second at four years old. But here's where it gets tricky: many adults and older children may have missed their second dose, leaving them vulnerable.
Who's most at risk? The health unit highlights several groups. Children aged four to six, older kids who missed their second MMR dose, and those born after 1970 planning international travel should all receive the second dose. Additionally, healthcare workers, post-secondary students, and adults advised by their doctors are also urged to get vaccinated.
And this is the part most people miss: infants aged six to 11 months traveling to high-risk areas can get an early first dose after consulting with their healthcare provider. Plus, Canadians born before 1970 are generally considered immune, but if they're traveling abroad without a history of measles or vaccination, a dose is recommended.
Measles doesn't discriminate; it can affect anyone who isn't fully vaccinated. Symptoms include fever, runny nose, cough, irritability, red eyes, and sometimes white spots in the mouth. After a few days, a blotchy rash appears, and complications can be severe, including ear infections, pneumonia, and even encephalitis (brain swelling).
