Researchers at the University of Arizona are working to curb coronavirus outbreaks at the school by conducting regular tests of sewage from 20 buildings across campus, and it seems to be working.
The university said it stopped a potential outbreak before it started after it analyzed wastewater from a dorm for traces of the virus. Subsequently, two students — both of whom were asymptomatic — were found to be infected. While Arizona is utilizing other mitigation tactics like swab testing and contact tracing, wastewater testing comes in handy because its reportedly sensitive enough to detect the virus up to a week before an individual develops symptoms, which means there's a better chance of locating a case before the person can spread the virus widely. "So, you have seven precious days in which you can undergo intervention," said Ian Pepper, an environmental microbiologist who is leading the effort.
