Wasterwater Surveillance Techniques Used for COVID Being Adapted for Monkeypox

(By Mark Kreidler, Wisconsin Public Radio) The same wastewater surveillance techniques that have emerged as a critical tool in early detection of COVID-19 outbreaks are being adapted for use in monitoring the startling spread of monkeypox across the San Francisco Bay Area and some other U.S. communities.

According to Mark Kreidler of Wisconsin Public Radio, before the COVID pandemic, wastewater sludge was thought to hold promise as an early indicator of community health threats, in part because people can excrete genetic evidence of infectious diseases in their feces, often before they develop symptoms of illness. Israel has for decades monitored wastewater for polio.

But before COVID, such risk monitoring in the U.S. was limited largely to academic pursuits. With the onset of the pandemic, a research collaboration that involves scientists at Stanford University, the University of Michigan, and Emory University pioneered efforts to recalibrate the surveillance techniques for detection of the coronavirus, marking the first time that wastewater has been used to track a respiratory disease.

That same research team, the Sewer Coronavirus Alert Network, or SCAN, is now a leader in expanding wastewater monitoring to detect monkeypox, a once-obscure virus endemic to remote regions of Africa that in a matter of months has infected more than 26,000 people globally and more than 7,000 across the U.S.

The Biden administration last week declared the monkeypox outbreak a public health emergency, following similar decisions by health officials in California, Illinois and New York.

And SCAN's scientists envision a future in which wastewater sludge serves as a reservoir for tracking a slew of menacing public health concerns. "We're looking at a whole range of things that we might be able to test for," said Marlene Wolfe, an assistant professor of environmental health at Emory.
