World Cup 2026: Health Officials Brace for Measles and Flu, But Dismiss Ebola Threat

As the 2026 FIFA World Cup prepares to kick off on June 11, 2026, across 16 host cities in the United States, Canada, and Mexico, global health officials are sharpening their focus on infectious disease threats. While an ongoing Ebola outbreak in the Democratic Republic of Congo and Uganda has drawn attention, experts agree the greatest risks come from far more contagious airborne pathogens.

"The overall likelihood of Ebola risk is low." — Dr. Shruti Gohil, University of California, Irvine Health

Risk Assessment: A Tale of Two Threats

Ebola: The Low-Risk Wildcard

Despite the active outbreak in Central Africa, experts maintain that the chance of widespread Ebola transmission during the tournament is minimal. The virus requires direct contact with the bodily fluids of a symptomatic individual, making it a poor candidate for mass transmission in a stadium setting.

"Ebola patients are very sick and unlikely to attend large events." — Dr. Amesh Adalja, Johns Hopkins Bloomberg School of Public Health

Enhanced entry screening is already in place for travelers arriving from affected countries, including Congo, Uganda, and South Sudan. The CDC has designated specific airports for these travelers and implemented a 21-day monitoring period.

Measles: The Top Concern

Measles has emerged as the single greatest public health worry for tournament organizers. In 2025, the United States recorded over 2,100 cases—the highest number since 1991—with the vast majority occurring among unvaccinated individuals.

"Measles is the biggest concern due to its high contagiousness." — James Garrow, Philadelphia Department of Public Health

Respiratory Viruses: COVID-19 and Influenza

Airborne transmission makes COVID-19 and seasonal influenza persistent threats. Unlike Ebola, these viruses can spread rapidly in crowded environments like stadiums, public transit, and fan zones.

"Airborne diseases like COVID-19 and flu are more likely to cause public health threats than Ebola." — Dr. Theresa Tran, Houston Health Department

Other Risks on the Radar

Health officials are also preparing for:

• Norovirus and foodborne illnesses, tied to mass gatherings and food vendors.
• Heat-related illnesses, given the summer timing and varied host city climates.
• Arboviruses such as dengue, which may circulate in warmer host regions.

Public Health Preparations: A Coordinated Response

Surveillance and Monitoring

Wastewater monitoring and other new surveillance tools have been scaled up across host cities. The CDC has implemented enhanced entry measures for travelers from affected regions, including designated airports and 21-day symptom monitoring.

Local Coordination

Local health departments are working closely with emergency responders and hospitals to ensure readiness. Dr. Phil Huang of the Dallas County Health Department noted that lessons learned from the 2014 Dallas Ebola case are being applied, including coordination protocols for isolation and contact tracing.

"We are coordinating with emergency responders and hospitals, using lessons from the 2014 Dallas Ebola case." — Dr. Phil Huang, Dallas County Health Department

Provider Education and Prevention

Health departments are educating medical providers on travel history collection, symptom recognition, and infection control procedures. Dr. Marvia Jones of the Kansas City Health Department confirmed that travelers from affected regions are being monitored.

Food Safety and Heat Prevention

Dr. Monika Roy of the Santa Clara County Health Department stated that departments are ensuring all food vendors have proper permits. Heat illness prevention campaigns are also underway across host cities.

Contract Tracing Capabilities

Health departments have confirmed they are prepared to conduct contract tracing for vaccine-preventable diseases, including measles and COVID-19, should outbreaks occur.

FIFA’s Position

FIFA issued a statement acknowledging the ongoing Ebola outbreak, noting that it is monitoring the situation and working closely with host governments to ensure a safe tournament for all participants and spectators.

Summary: While Ebola dominates headlines, the real game-day threats for the 2026 World Cup are measles, flu, and COVID-19. Health officials are leveraging lessons from past outbreaks and deploying enhanced surveillance, screening, and vaccination strategies to keep fans safe.
