Since June 2020, the SARS-CoV-2 Immunity and Reinfection Evaluation (SIREN) study has conducted routine PCR testing in UK healthcare workers and sequenced PCR-positive samples. SIREN detected increases in infections and reinfections and detected Omicron subvariant emergence contemporaneous with national surveillance. SIREN methodology can be used for variant surveillance.
