A measles case in suburban Montreal has raised concerns about possible community transmission of the virus in Quebec, according to health officials. The case reported in Laval on Feb. 27 involved a person who had not traveled abroad or been in contact with another known case. The local public health agency stated that “local community transmission is therefore possible” in a notice sent to health-care professionals on Feb. 29.
Public health officials are now working to identify and notify individuals who may have come into contact with the infected person while still contagious. The person reportedly visited an elementary school and convenience store in Laval, as well as the Sainte-Justine children’s hospital in Montreal during that time. This measles case is the third confirmed in Quebec in recent weeks, with the lack of a connection to international travel suggesting possible circulation of the virus within the province.
Following two other cases at the beginning of February involving a person who had traveled to Africa and a family member, Montreal public health director Dr. Mylène Drouin urged families and local school staff to check their measles vaccination status. Dr. Drouin emphasized the presence of measles in many countries and the need for caution with the upcoming spring break and travel resumption. Public health officials are asking the public to ensure they are fully vaccinated against the virus, as the potential for imported cases leading to community transmission remains a concern.
