Show abstract

Wastewater was screened for the presence of functionally significant mutations in SARS-CoV-2 associated with emerging variants of concern (VOC) by ddPCR, and results accorded with sequencing of clinical samples from the same region. We propose that PCR-based screening of wastewater can provide a powerful tool for rapid and inexpensive screening of large population segments for VOC-associated mutations and can hone complementary sampling and sequencing of direct (human) test material to track emerging VOC.
