Monitoring wastewater for traces of infectious diseases is giving this human byproduct a powerful new role in public health. Once used decades ago to detect poliovirus, wastewater-based epidemiology reemerged during COVID-19 and is now proving useful again in tracking measles outbreaks before cases are officially reported.
