Step up measles vaccinations, say doctors as outbreaks accelerate in Ontario, Alberta

The measles outbreaks in Ontario and Alberta have been steadily growing, prompting doctors to urge public health officials to increase vaccination efforts and messaging. In Ontario, there were 223 new confirmed and probable cases of measles reported in the past week, with a total of 210 confirmed cases in Alberta as of May 2nd.

Dr. Sarah Wilson, a public health physician with Public Health Ontario, noted that this recent surge in cases is the largest increase since the outbreak began in October of 2024. The majority of cases in Ontario are concentrated in the Southwestern Public Health region, with 84 individuals, including 63 children, requiring hospitalization. Eight patients were hospitalized in the last week, with seven needing intensive care.

Measles is a highly contagious disease that can cause fever, cough, red watery eyes, and a blotchy rash. Despite the availability of a vaccine, vaccination rates are below the recommended threshold of 95% in many areas. Factors contributing to low vaccination rates include disruptions caused by the COVID-19 pandemic and the spread of vaccine misinformation online.

Dr. Mark Joffe, Alberta’s former chief medical officer of health, criticized the lack of leadership at all levels and highlighted the public complacency surrounding the outbreak. He emphasized the need for targeted messaging and outreach to communities with low immunization rates.

In both provinces, vaccination coverage for measles falls below the recommended level of 95%, with some regions reporting rates as low as 24.6%. Access to primary care providers and underreporting of immunization status have also been identified as barriers to vaccination.

Countering misinformation about vaccines is another significant challenge, with social media platforms being used to spread false information. Dr. Michael Gardam, an infectious diseases physician, emphasized the need for proactive public health messaging to promote vaccine uptake and combat misinformation.

Efforts are being made to increase vaccination rates and educate the public about the importance of measles immunization. Public health officials are working to address vaccine hesitancy, provide accurate information about vaccines, and ensure access to vaccination clinics. Weekly updates from provincial health authorities and expanded vaccination options, including pharmacies, are being recommended to enhance public awareness and protection against measles.

Overall, the ongoing measles outbreaks in Ontario and Alberta underscore the importance of vaccination and public health interventions in preventing the spread of infectious diseases. By addressing barriers to vaccination, countering misinformation, and increasing public awareness, communities can work together to protect vulnerable populations and mitigate the impact of outbreaks.
