“This expanded wastewater surveillance network around the globe has a vast potential for the future.” Rotary senior staff writer Diana Schoberg explains how the evolution of the GPEI’s surveillance system during the COVID-19 pandemic can bring us closer to polio eradication. Looking ahead, the new infrastructure can also be used for surveillance of other viral illnesses. This audio version of a story in the October 2023 issue of Rotary magazine is narrated by Andy Choi.
