Early results from a Michigan project to monitor the levels of COVID-19 in wastewater show promising results. “These initial results show promise for the field of COVID-19 wastewater monitoring in Michigan,” said Sarah Lyon-Callo, director of the Bureau of Epidemiology and Population Health at MDHHS. “This project has demonstrated the feasibility of this laboratory method and local partnerships for a longer-term wastewater surveillance system. Nineteen laboratories across the state of Michigan are participating in a standardized and coordinated network of COVID-19 wastewater monitoring systems.
