Measles Outbreak: 26 Cases in B.C. in One Week
The recent surge in measles cases in British Columbia has raised concerns, with 26 new cases reported between October 30 and Thursday, according to the BC Centre for Disease Control (BCCDC). This spike is primarily attributed to the Northern Health Authority, which accounts for nearly 80% of all cases reported this year. The region's northeast area has seen a significant impact, with 251 confirmed cases in 2025.
Dr. Brian Conway, medical director at the Vancouver Infectious Diseases Centre, expressed disappointment over the latest outbreak. He highlights that the Northern region is the only one to have recorded new cases in the last month, apart from a single case in the Fraser Health Authority. Conway suspects that the conditions in Northern B.C. play a role, as indoor gatherings in confined spaces can increase contagion, especially in colder climates like northeastern British Columbia.
However, the primary factor behind the outbreak is believed to be vaccination rates. Before the outbreaks began, vaccination rates in northeastern British Columbia were as low as 50%, significantly lower than the 90% needed to prevent community-based outbreaks. Conway emphasizes the importance of vaccination in preventing measles transmission, urging the public to take this recent surge as a cautionary tale.
Comparatively, Alberta reported 1,917 cases between October 2024 and October 2025, while Ontario recorded 2,371 cases. Health Canada declared Ontario's outbreak over last month, indicating a potential shift in the regional dynamics of the disease.
