Researchers at leading universities in Mexico are among those around the world adopting methods of detecting the spread of COVID-19 that have become a major focus of work in ASU’s Biodesign Center for Environmental Health Engineering. Fulton Schools Professor Rolf Halden (center in photo), the center’s director, and Associate Research Scientist Erin Driver (at right) are leaders in wastewater epidemiology, which involves analyzing wastewater to detect signs of community health risks, including levels of COVID-19 infection. A related technique, called sewage metrology is also being used to reveal the genetic indicators of the coronavirus in the materials found in wastewater.
