As the FIFA World Cup approaches Vancouver, experts are raising concerns about the potential for increased measles transmission during the event. This issue is particularly pertinent given Canada's recent loss of its measles elimination status.
The Public Health Agency of Canada has issued a warning, highlighting the high likelihood of measles importation during the tournament due to its global prevalence and airborne transmission. Ontario, which has already released a detailed risk assessment, echoes these concerns, citing crowded venues, international travel, and declining vaccination rates as potential catalysts for measles outbreaks.
The Vancouver Perspective
In Vancouver, the lack of visible public messaging and a publicly released risk assessment ahead of the tournament has caused concern among medical professionals. Dr. Brian Conway, medical director of the Vancouver Infectious Diseases Centre, emphasizes the need for planning and public awareness. He suggests encouraging visitors to verify their vaccination status and warns that Vancouver is an active measles zone.
Measles Cases and Outbreaks
Measles cases have been on the rise in Canada, with over 900 reported across seven jurisdictions so far this year. The bulk of these cases are in Alberta and Manitoba, with B.C. reporting 470 cases in 2025-26, primarily concentrated in the province's northeast, where immunization rates are among the lowest.
Past Outbreaks and Current Trends
Historically, Vancouver has experienced measles outbreaks following major sporting events, such as the 2010 Winter Olympic Games. Dr. Conway highlights that with declining vaccination rates in B.C. and even lower rates in some parts of the world where athletes and tourists will be coming from, the risks of importing cases are heightened.
Planning and Preparedness
Vancouver Coastal Health (VCH) has been planning for the World Cup for several years and has completed a public health risk assessment with the B.C. Centre for Disease Control. Dr. Mark Lysyshyn, deputy chief medical health officer with VCH, classifies the measles risk during the tournament as "medium or moderate." He notes that while VCH has dealt with measles importations during the current outbreak, there haven't been any active cases within the region due to the health region's good immunization rates.
The City of Vancouver assures that it has comprehensive operational and emergency management plans in place to respond to any issues that may arise.
Expert Insights
Dr. Monika Naus, a professor at the University of British Columbia's School of Population and Public Health, emphasizes that large international gatherings always carry the risk of infectious disease spread. However, she believes the overall risk to the broader public remains limited due to most adults' immunity to measles. Her primary concern lies with under-vaccinated communities, which she identifies as the main vulnerabilities within B.C.
Regaining Elimination Status
Canada can regain its measles elimination status if transmission is interrupted for a full year. This goal, however, seems challenging given the current circumstances and the potential for increased transmission during the FIFA World Cup.
In my opinion, the upcoming FIFA World Cup in Vancouver presents a unique challenge for public health officials. While the event promises to be a celebration of sports and culture, it also highlights the ongoing battle against measles and the importance of vaccination. The potential for increased transmission during such a large-scale gathering is a concern that requires proactive planning and public awareness. The experts' insights provide a deeper understanding of the situation and the steps being taken to mitigate risks. Personally, I believe that open communication and education are key to ensuring a safe and enjoyable tournament for all.
