Ontario reports spike in measles cases linked to N.B. exposure

A growing cluster of measles cases in Ontario, linked to an exposure in New Brunswick, has now reached 37 cases, according to public health officials. Of these cases, 11 have been confirmed while 26 are considered probable.

The outbreak began in October and has predominantly affected children and teenagers, with 28 of the cases falling within this age group. Alarmingly, all but two of the cases were in individuals who were unimmunized against the measles virus.

This surge in measles cases is particularly concerning given the historical data on measles in Ontario. Public Health Ontario reports that between 2013 and 2023, there were only 101 confirmed cases of measles in the province, with no more than 22 cases in any given year. In comparison, this year alone has seen 63 cases, with eight resulting in hospitalization and tragically, one death.

The measles virus is highly contagious and symptoms typically include fever, a red blotchy rash, red watery eyes, and cough. Vaccination is the most effective way to prevent the spread of measles and protect against its potentially serious complications.

The recent outbreak has reignited calls for a national vaccination registry in Canada, as experts point out that the lack of a centralized system hinders efforts to track and contain outbreaks. A national registry could help ensure that individuals are up to date on their vaccinations, ultimately safeguarding public health.

As Ontario grapples with this surge in measles cases, it serves as a stark reminder of the importance of vaccination in preventing the spread of infectious diseases. Public health officials continue to urge individuals to ensure they and their families are immunized against measles and other vaccine-preventable illnesses to protect both themselves and the wider community.
