COVID data quietly disappears while cases rise

California-based engineer and scientist Patrick Vaughan made a troubling discovery July 10. Dozens of facilities providing COVID-19 wastewater data went offline, seemingly overnight.

Vaughan had been following WastewaterSCAN, a national program that monitors wastewater for diseases. He noticed that 42 of the previously reporting 194 facilities suddenly displayed small blue triangles with the message “data is no longer collected from this site.” The development came just as people across the U.S. scrambled for information during a summer COVID wave that even infected President Joe Biden.

“This is a major blow to our COVID wastewater tracking abilities,” Vaughan told his followers in a video he posted the same day.

A series of crucial setbacks in Covid-19 testing has made it difficult to keep up with the virus’ rapid spread, and has inspired some researchers to look to wastewater to help fill in the gap of measuring how prevalent SARS-CoV-2 is in a given community.

In a paper posted Tuesday to the preprint server medRxiv, researchers collected samples in late March from a wastewater treatment plant serving a large metropolitan area in Massachusetts and found that the amount of SARS-CoV-2 particles in the sewage samples indicated a far higher number of people likely infected with Covid-19 than the reported cases in that area.
