An outbreak of SARS-CoV-2 in a public-facing office in England, 2021

Between August-September 2021, an outbreak of SARS-CoV-2, with an attack rate of 55% (22/40 workers), occurred in a public-facing office in England. To identify workplace and worker-related risk factors, a comprehensive investigation involving surface sampling, environmental assessment, molecular and serological testing, and worker questionnaires was performed between 3 September and 27 October 2021. The results affirm the utility of surface sampling to identify SARS-CoV-2 control deficiencies and the importance of evolving, site-specific risk assessments with layered COVID-19 mitigation strategies.
