Researchers are sounding the alarm over the significant risk of communicable diseases at the 2026 FIFA World Cup. The event, hosted across Canada, the United States, and Mexico, has already drawn record-breaking crowds, with over 4.6 million attendees in its first 72 matches. This unprecedented scale of international movement creates conditions ripe for the transmission of pathogens.
Experts draw on past mass gatherings to stress the need for robust public health measures. Key strategies include pre-travel counseling, vaccination campaigns, enhanced surveillance, and rapid outbreak response systems. The identified disease risks span from common respiratory viruses like influenza and COVID-19 to vector-borne illnesses such as dengue and zika, as well as foodborne infections and vaccine-preventable diseases like measles.
Recommended vaccines for attendees include measles-mumps-rubella, tetanus-diphtheria-pertussis, influenza, COVID-19, and hepatitis A and B. Authorities call for strengthened international collaboration to mitigate this public health challenge.
