Dr. Theresa Tam, Canada’s chief public health officer, has issued a warning regarding the rising number of confirmed measles cases in the country. According to Tam, there have been 40 confirmed cases of measles in Canada so far in 2024, which is more than three times higher than the total number of cases recorded in 2023.
Tam expressed concern over the insufficient vaccination coverage among school-aged children, emphasizing the importance of ensuring that children receive all measles vaccines according to schedule. She urged parents and caregivers to verify their child’s vaccination status with their healthcare provider or local public health agency if uncertain.
The measles-containing vaccines are highly effective and offer significant benefits in preventing severe illness, Tam emphasized. Despite this, many cases of measles in Canada have occurred among unvaccinated individuals, particularly children.
Quebec has reported the highest number of measles cases this year, with 28 confirmed cases, followed by Ontario with 10 cases, and one case each in British Columbia and Saskatchewan. Seven individuals have been hospitalized due to measles this year.
Tam noted that while some cases have been linked to international travel, others have been acquired within Canada. She highlighted the importance of vaccination, especially as people prepare for family gatherings and religious celebrations.
The increase in measles cases is attributed to both increased measles activity worldwide and suboptimal vaccine uptake nationally, according to Tam. She acknowledged efforts by local public health agencies to catch up on routine vaccinations, especially following potential disruptions during the COVID-19 pandemic.
Symptoms of measles include fever, red watery eyes, runny nose, cough, and a distinctive red rash. Measles can lead to severe complications, including deafness, brain inflammation, and even death. Achieving a 95 percent vaccination rate is crucial for herd immunity against measles.
Despite recent increases in public interest in vaccination, national data from 2021 showed that only 79 percent of children had received two doses of measles vaccine by age seven.
Tam’s warning underscores the importance of maintaining high vaccination coverage to prevent measles outbreaks and protect public health in Canada.
