Measles Outbreak: 26 Cases in B.C. in One Week
In a concerning development, British Columbia has seen a surge in measles cases, with 26 confirmed infections reported in just one week. The BC Centre for Disease Control (BCCDC) has confirmed that all 26 cases originated from the Northern Health Authority, which accounts for nearly 80% of the total cases reported this year. This region, particularly its northeast area, has seen a significant spike, with 251 confirmed cases in 2025 alone.
Dr. Brian Conway, medical director at the Vancouver Infectious Diseases Centre, expressed disappointment over the recent increase in cases. He highlighted that the Northern region is the only one to have recorded new cases in the last month, aside from a single case in the Fraser Health Authority. Conway suspects that the unique conditions of Northern B.C. play a role in the outbreak.
He explained that the colder climate in the northeast area of the province encourages people to spend more time indoors, increasing the likelihood of contagion. Additionally, Conway emphasized the importance of vaccination rates, noting that before the outbreaks began, full vaccination rates in northeastern British Columbia were as low as 50%, far below the 90% threshold required to prevent community-based outbreaks. He stressed that vaccination is crucial in preventing the transmission of measles.
Comparatively, Alberta reported 1,917 cases between October 2024 and October 2025, while Ontario recorded 2,371 cases. Health Canada announced that Ontario's outbreak was declared over last month. This latest outbreak in B.C. serves as a stark reminder of the ongoing challenges in controlling measles and the critical need for high vaccination coverage to prevent further spread.
