Chief Medical Officer Sounds Alarm on Measles Epidemic in Ontario and Quebec
Concerned about the increasing number of measles outbreaks in Canada, the country’s top health official has highlighted a rise in cases in Ontario and Quebec.
Tam emphasized the rapid spread of measles, stating that 90% of unvaccinated individuals or those without prior measles exposure can become infected if in close proximity to an infected person.
The majority of recent cases in Canada have involved unvaccinated individuals, including a significant number of infants under one year old.
Out of the reported cases, 28 involved children and adolescents, while 10 were linked to adults.
Except for two cases, all individuals were unvaccinated. One case reported receiving a single dose of the measles vaccine, while another reported receiving two doses. One child required hospitalization.
The cases occurred in the Southwestern Public Health, Grey Bruce Health Unit, and Grand Erie Public Health areas of the province.
Another measles case was reported by Grand Erie Public Health, with the affected child currently recovering at home.
Individuals experiencing measles symptoms should contact a healthcare provider immediately and self-isolate at home to prevent transmission. Tam advised contacting healthcare facilities in advance to inform them of the suspected measles case.
Research published in the Canadian Journal of Public Health highlighted a decline in measles vaccination rates among children aged two to seven before, during, and after the COVID-19 pandemic.
