Pathogen Surveillance Framework for Paris 2024 Olympics: Tips for Public Health Wellness

Pathogen Surveillance Framework for Paris 2024 Olympics

French Public health experts have developed a model to identify priority pathogens for wastewater surveillance ( WWS ) at the upcoming Olympic and Paralympic Games in Paris . The study identified six target pathogens suitable for monitoring disease levels and guiding public health decisions during the mass gatherings expected to draw 16 million visitors . The viruses causing polio , flu , mpox , COVID-19 , and measles were among the pathogens chosen for WWS.

Selection Criteria and Expert Consensus

The selection of target pathogens was based on criteria informed by various health organizations and assessed by 32 experts . The pathogens had to be excreted in urine or feces , remain detectable in sewage , and have relevance to the event . The study narrowed down the list to 25 pathogens of interest before arriving at the final six target pathogens . Influenza A and B , in particular , were highlighted for their global impact on public health and potential transmission risks during the Olympic Games.

Public Health Benefits and Challenges

Wastewater surveillance has proven valuable during the COVID-19 pandemic , offering a non - intrusive , cost - effective method for monitoring pathogens . The data collected from WWS can provide insights into disease circulation regardless of symptomatic status , allowing for early warnings and informed decision - making in public health . While the framework for Paris 2024 is underway , further work is needed to optimize laboratory methods , sampling strategies , and pathogen detection for effective implementation.

Planning for Implementation and Future Applications

The study serves as a starting point for a WWS plan for the Paris games , utilizing France 's existing network of 54 wastewater treatment plants . Once a sampling strategy proposal is approved , operators and laboratories will be selected to carry out the surveillance . The plan aims to monitor the circulation of measles , influenza A , and influenza B viruses in Parisian wastewaters , providing a pilot for potential future applications of WWS in similar mass gathering events . If successful , the framework could encourage the adoption of WWS strategies for public health surveillance in various contexts beyond the Olympic Games.
