U.S. public health authorities have launched an extensive infectious disease surveillance effort as the 2026 World Cup brings an estimated 6.5 million fans to host cities across the United States, Mexico, and Canada over 39 days. The Centers for Disease Control and Prevention, working with local health departments, is integrating wastewater monitoring, hospital admission data, and digital surveillance to spot early signs of outbreaks. Officials are focused on common highly transmissible infections such as measles, norovirus, and mosquito-borne illnesses including dengue fever. Although the likelihood of rare, high-consequence pathogens like Ebola remains extremely low, hospitals in host cities have completed specialized readiness training to isolate and manage potential cases, aiming to prevent localized infections from spreading into wider community health problems.
