The European Centre for Disease Prevention and Control (ECDC) has released a threat assessment for the 2026 FIFA World Cup, warning that measles poses a high risk of importation and spread during the tournament. The analysis, published on May 14, 2026, cites ongoing measles outbreaks in several countries and large gatherings as key factors.
According to the ECDC, measles is estimated to have a high likelihood of importation due to its high transmissibility and the influx of travelers from regions with active outbreaks. The agency recommends ensuring high vaccination coverage and rapid case detection.
In contrast, mpox (formerly monkeypox) is assessed as a moderate risk because it spreads primarily through close contact, such as sexual partners or household members. The ECDC notes that while mpox cases continue to occur, the risk of widespread transmission at the World Cup is lower.
The ECDC urges public health authorities in host countries to strengthen surveillance and vaccination efforts. The World Cup is scheduled to take place from June 11 to July 19, 2026, across the United States, Canada, and Mexico.
