Measles activity increasing – clinical awareness and preparedness essential

Although measles remains officially eliminated in Canada, declining vaccination rates have led to a rise in imported and locally transmitted cases. As of June 19, 2025, B.C. has reported 32 confirmed cases—with clusters in Northern Health (20), Vancouver Coastal (8), and Fraser Health (4). Most involve un- or under-immunized individuals.

Given measles’ high transmissibility and potential for outbreaks, we encourage clinicians to review relevant clinical resources, ensure MMR immunization is up to date for patients, and remain alert to early presentations, particularly among returning travellers or contacts in affected regions.

Health authorities are offering vaccine opportunities in advance, learn more about clinics or where to call for more information in your region:

• Vancouver Coastal Health
• Fraser Health
• Interior Health
• Island Health
• Northern Health

Here are some relevant resources and quick links to help you look out for signs of measles, so you can quickly isolate the patient and prevent spreading the virus to others in your ED:
