- [Pre-print, not peer-reviewed] Between October 2020 and January 2021, a rapid increase in the SARS-CoV-2 variant B.1.1.7 was detected in sewage samples in England. Viral RNA containing B.1.1.7 mutations was first identified in a sample collected in London on November 10 and detected in 7-9% of all sewage samples in November, increasing to >95% by January 2021. The authors suggest that environmental surveillance of sewage may provide an early warning of potential spread of specific variants of concern.
