Epidemiologists and public health specialists will be actively screening sewage and scanning internet activity this summer in an effort to detect infectious disease threats tied to the World Cup, one of the largest and most internationally diverse mass gatherings in recent memory.
A team based at a converted Georgetown University laboratory in Washington, D.C., has been organized to compile near real-time surveillance using wastewater testing, anonymized electronic health records and open-source social media signals. Organizers said the group will monitor disease activity in the U.S. and Canadian cities hosting World Cup teams, matches and the millions of spectators expected to travel to the region.
The event spans 39 days and begins in Mexico on Thursday. Organizers expect more than 6.5 million fans from over 100 countries to attend 104 matches staged across the United States, Canada and Mexico. The scope and international movement associated with the tournament create conditions that can facilitate rapid transmission of pathogens, public health experts say.
Operations center and mission
The operations hub at Georgetown serves as a coordination point linking academic institutions, non-profit groups and private firms that are supporting government bodies. It was launched in partnership with the MedStar Health regional hospital system and will issue a daily status report highlighting emerging risks and any immediate actions that hospital emergency managers and public health officials at local, state, federal and international levels should consider.
Those briefings will also be made available to FIFA, the tournament organizer. Organizers described the operations center in Washington as both an active monitoring effort for the current tournament and a rehearsal for future large-scale events, including the 2028 Summer Olympics in Los Angeles. MedStar operates one of the nation's 13 biocontainment units.
Wastewater sequencing and other surveillance tools
A cornerstone of the monitoring approach is advanced wastewater analysis. The technique uses DNA and RNA sequencing to detect genetic fragments from a broad range of microbes directly from sewage samples - without the need to culture organisms in a laboratory. Rebecca Katz, director of Georgetown's Center for Global Health Science and Security and leader of the surveillance effort, described the method as "incredibly powerful." Katz and her team are receiving sequencing and related wastewater data from collection sites in the U.S. and Canada, along with other health-monitoring inputs from all three host countries.
In addition to sewage testing, the operations center will synthesize anonymized electronic health record data and conduct "social listening" by scanning public social media for patterns that could indicate clusters of illness. Katz cited a prior example in which officials used online chatter about an increase in toilet paper purchases to help pinpoint an outbreak of gastrointestinal illness.
Diseases of concern and targeted monitoring
Detecting pathogen signatures in wastewater can provide advance warning of emerging outbreaks, allowing clinicians to be alerted to watch for particular symptoms that might otherwise be misdiagnosed and giving health authorities time to recommend preventive measures to the public. The team intends to maintain a broad watch but will pay particular attention to several specific threats mentioned by organizers.
One focus is measles, which is approaching a record number of cases in the United States this year - about 2,000 so far - and has seen resurgences in parts of Mexico and Canada. Mosquito-borne viral illnesses such as dengue - often referred to as "breakbone fever" - and chikungunya are also on the radar. Both illnesses originate in tropical regions and can be transported by infected travelers and subsequently transmitted locally by mosquitoes.
The current Ebola outbreak in Africa has drawn intense media interest. Katz said that while hemorrhagic fever can be fatal, it represents a "very low risk to the general public" in North America. She noted that World Cup team and support staff from the Democratic Republic of Congo, the country at the center of the Ebola outbreak, underwent precautionary quarantine in Belgium prior to traveling to the United States, and that most of those players were in Europe when the outbreak began.
Partnerships, resources and scope of effort
Katz assembled a core group of 20 colleagues, supplemented by pro bono support and assistance from 30 other organizations. Several wastewater surveillance companies are collecting and screening sewage samples and are sharing their data with the Georgetown team at no charge. The operations center will augment the monitoring activities of U.S. agencies, including the Centers for Disease Control and Prevention and the Administration for Strategic Preparedness and Response, according to organizers.
Financial contributions for the center have come from a small family foundation and Georgetown University, with in-kind aid from partners such as the University of Nebraska. The initiative combines direct laboratory sequencing capacity, hospital-based assets through MedStar and shared data feeds from private and public partners.
Outlook and limitations
Organizers emphasize that the surveillance effort is designed to provide situational awareness and early warning rather than to eliminate all risk. They also noted constraints on U.S. public health capacity amid ongoing responses to multiple outbreaks - including measles, Ebola and hantavirus - both domestically and internationally. They cited budget and staffing reductions during the prior federal administration and the U.S. withdrawal from the World Health Organization as factors that have heightened those challenges.
The Washington-based operations team will continue to compile daily reports and coordinate with public health authorities should signals emerge that warrant further investigation or immediate action. The center's leaders view this concentrated monitoring effort as both a response to the current tournament and a model for surveillance at future major international gatherings.
