COVID cases are going up in many countries as dangerous new subvariants evolve faster and faster. At the same time, individual testing is going down.
That might seem like a dangerous combination. If authorities can’t accurately keep tabs on where and how fast the virus is spread, they might not be able to help protect vulnerable communities.
Fortunately, there’s one way to track SARS-CoV-2 without relying on drive-through testing sites or testing at pharmacies, clinics or hospitals. More and more, scientists are looking for the virus in sewer water. In our toilet flushes, in other words. “Wastewater seems to be the key to early detection, especially in the context of increased at-home testing and potentially reduced reporting,” Niema Moshiri, a geneticist at the University of California, San Diego, told The Daily Beast.
