The Pan American Health Organization (PAHO) has issued health advisories ahead of the 2026 FIFA World Cup, warning of potential outbreaks of measles, COVID-19, and dengue due to the large-scale international gathering. The recommendations emphasize vaccination campaigns, hygiene protocols, and surveillance measures to mitigate risks for travelers and residents in host regions.
Health Risks Highlighted by PAHO
PAHO identified measles, COVID-19, and dengue as priority concerns, citing their high transmissibility and potential for rapid spread in densely populated areas. Measles, which remains uncontrolled in some regions, could pose a significant threat to unvaccinated attendees. COVID-19 variants continue to circulate globally, while dengue, prevalent in parts of North and South America, may surge during the tournament’s timing in June and July.
“Mass gatherings like the World Cup create conditions that can accelerate disease transmission,” said a PAHO spokesperson. “Proactive measures are essential to protect public health and ensure the event proceeds safely.”
Recommendations for Travelers and Attendees
The organization urged travelers to verify vaccination status, particularly for measles and COVID-19, and to follow local health guidelines. Public health authorities in host countries—Mexico, Canada, and the United States—are being advised to strengthen surveillance systems and prepare healthcare facilities for increased demand.
PAHO also emphasized the importance of mosquito control efforts in dengue-endemic areas, including community education and environmental management to reduce breeding sites. Travelers are advised to use insect repellent and wear protective clothing in high-risk zones.
Context and Precedent
This guidance aligns with lessons from previous large-scale events, such as the 2020 Tokyo Olympics, where health protocols were critical in managing COVID-19. However, the 2026 World Cup presents unique challenges due to its transnational nature and the coexistence of multiple health threats.
Public health experts noted that while the risk of outbreaks is real, it is manageable with coordinated efforts. “The key is balancing the excitement of the event with the responsibility to protect vulnerable populations,” said Dr. Laura Fernández, a global health researcher not affiliated with PAHO.
What’s Next
PAHO plans to conduct follow-up assessments as the event approaches, adjusting recommendations based on evolving epidemiological data. Host nations are expected to finalize their own health strategies in the coming months, with a focus on cross-border collaboration and resource allocation.
