As more than five million people travel to North America for the World Cup across 16 host cities, public health experts are running simulations for outbreaks and using wastewater surveillance led by Georgetown University and MedStar Health to detect pathogens
Happy Monday, but for public health officials, the calendar is already crowded.
With the World Cup set to kick off in just a few days. more than five million people from around the world are expected to travel to North America this week. Sixteen different cities will host the games. and the excitement comes with a practical problem: how to spot infectious disease threats before they spread widely.
New York City’s health commissioner recently told NPR that the city has been running simulations to prepare for mass casualty events and disease outbreaks. Those kinds of drills matter when large crowds and dense transit collide—something many travelers are already thinking about. even as public health teams focus on what could go wrong.
Across several World Cup locations in the U.S. officials are also turning to a surveillance tool that can offer an early read on what pathogens might be circulating. Wastewater monitoring. used to detect genetic material shed into sewage via skin or saliva. is being scaled up as a forecasting system.
The Wastewater Surveillance Network is being led by Georgetown University and MedStar Health. assembling partners around the country to monitor wastewater. The system is designed to detect pathogens including COVID, measles, and influenza. Researchers are also watching for insect-borne illnesses such as chikungunya and dengue.
To sharpen the picture further, the team includes a genomics component. Viruses are being sequenced to help trace possible outbreaks. Information is then meant to flow quickly: the network will use real-time dashboards to share details with both the public and public health officials. enabling actions aimed at containing outbreaks.
Ebola remains part of the backdrop for scientists assessing risks tied to travel. The host of the roundup said she is keeping tabs on the ongoing Ebola outbreak. noting that scientists are concerned about cases emerging in North America as people travel for the games. She also reported that while the Wastewater Surveillance Network does have the capability of detecting the virus. team members she spoke with are “not as concerned about Ebola spread in the U.S. right now” compared with threats like measles or influenza.
The method is built for speed and specificity, but it also reflects a modern reality: with millions moving at once, the question isn’t just whether pathogens will appear—it’s how quickly systems can notice and respond before a localized problem becomes widespread.
