Ebola Risk for US Travelers During World Cup Remains Low, Experts Confirm Preparedness

As the 2026 FIFA World Cup enters its second week, infectious disease experts say the risk of an Ebola-infected traveler arriving in the United States is "extremely low" — but not zero. An active outbreak of the Bundibugyo strain of Ebola is spreading in the Democratic Republic of the Congo and Uganda, with 808 confirmed cases and at least 192 deaths in the DRC alone, according to Reuters.
Dr. Tom Frieden, former CDC director, put it plainly: "Low isn't zero, and it won't be zero until the outbreak is stopped at the source." Still, experts say the U.S. is better prepared than ever — and that common diseases like measles pose a far greater real-world threat to the tournament's 6.5 million traveling fans.
The current outbreak involves the Bundibugyo strain of Ebola — not the better-known Zaire strain. That distinction matters. There is no approved vaccine or targeted treatment for the Bundibugyo strain, according to UTHealth Houston. The fatality rate is running between 20% and 24%, based on WHO and ECDC data.
The WHO declared a Public Health Emergency of International Concern on May 16. Uganda reported its first cases — 19 confirmed, 2 deaths — shortly after. The DRC recorded its first theorized infections back in February, in the Ituri Province. Officials only declared the outbreak on May 14.
The U.S. response strategy was built on the lessons of a painful failure. In 2014, Thomas Eric Duncan traveled from Liberia to Dallas, was turned away from a hospital, and later died. Two nurses who treated him got infected. That disaster prompted the U.S. to spend $260 million on Ebola readiness, creating 13 specialized treatment centers nationwide, according to Malay Mail.
Dr. Gavin Harris of Emory University said the U.S. is "the most prepared that we have ever been." The CDC and Department of Homeland Security began enhanced airport screenings on May 18. The U.S., Mexico, and Canada issued a joint statement on aligned public health travel measures on May 28 — a historic first for a mega-sporting event, according to Al Jazeera.
Multiple experts warn that Ebola is not the disease most likely to spread through packed stadiums. Dr. Krutika Kuppalli of UT Southwestern said she is "most worried about measles" because of how easily it spreads in large crowds, according to The Washington Post. Dr. Amesh Adalja of Johns Hopkins called the World Cup a classic "mass gathering event" where respiratory and stomach bugs are statistically far more likely than Ebola.
For the first time at this scale, health officials are tracking disease in real time using wastewater surveillance, hospital visit data, and social media, according to WHYY. The tournament runs 39 days across 16 cities — a long runway for any pathogen to spread. Officials say the bigger day-to-day concern for emergency rooms this summer is heat, measles, and norovirus — not Ebola.
The U.S. has banned non-citizens traveling from the DRC, Uganda, and South Sudan. On June 1, that ban was extended to some green card holders, according to Al Jazeera. Critics — including the WHO — argue travel bans can push infected people to hide symptoms and avoid reporting, making outbreaks harder to contain.
Dr. Jennifer Layden of Washington University warned that recent CDC budget and staffing cuts have weakened the broader public health safety net. Dr. Rebecca Katz of Georgetown put it more bluntly, telling WHYY that the CDC is now "a shell of what it once was." Experts say the government can handle one Ebola case — but a widespread measles outbreak across 16 cities would strain a system already running thin.
