Wastewater surveillance is a powerful new tool for tracking diseases in communities. I'm Amy Kirby, the team lead for the National Wastewater Surveillance System or NWSS. With public, private, academic and utility partners, our system can provide an early warning of increases in COVID-19 to local  and tribal health agencies. And it can be used to track new variants. In 2022, NWSS expanded in both scope and size. When NWSS first started in 2020, wastewater testing was only conducted in five communities. Now that number is over 1200, covering more than 138 million Americans. That's two in five. And last year, NWSS expanded beyond COVID-19 and was used to detect mpox during the outbreak, proving its importance in the future of infectious disease control. Now we're exploring how the system can be used for other diseases like E. coli and flu, and emerging problems like Candida auris and antimicrobial resistance. The NWSS platform was built to be rapidly adaptable to changing public health needs. So as those new needs emerge, we're ready to test, adapt, and expand on the strong foundation that we've built.
