The 2026 FIFA World Cup featured 48 national teams and millions of visitors across 16 cities in the United States, Canada, and Mexico over 39 days. Behind the scenes, the Centers for Disease Control and Prevention (CDC) maintained a sustained public health response to protect fans, travelers, and host communities. This multi-year preparation was part of a coordinated federal effort led by the White House FIFA World Cup Task Force, which intensified as the tournament approached. The CDC's Office of Readiness and Response regularly consulted with public health officials from all 11 U.S. host sites and federal partners to exchange information in real time.
To support state, tribal, local, and territorial (STLT) epidemiologists, the CDC worked with the Council of State and Territorial Epidemiologists (CSTE) to provide Applied Epidemiology Recommendations for mass gatherings preparedness and response. This included integrating surveillance, data systems, and staffing into World Cup planning. CDC fellows and field officers already placed in health departments provided on-the-ground support to ensure rapid local response capabilities.
Because fans frequently traveled between multiple cities and countries during the tournament, the CDC developed a specialized data dashboard giving health departments a shared, cross-jurisdictional view of disease trends and environmental factors like heat and air quality. This allowed prioritization of community-specific health concerns in real time.
Throughout the event, CDC's disease detection infrastructure was fully operational. Its 20 port health stations implemented continuous protocols at U.S. points of entry in cooperation with U.S. Customs and Border Protection. Public health messaging was also delivered via monitors at major international airports serving host cities. When other public health threats emerged during the tournament, including outbreaks of Ebola, hantavirus, and measles, the CDC incorporated World Cup surveillance into its broader response efforts.
