Abstract
Given the recent surge in SARS-CoV-2 Omicron infections, we performed a quantitative PCR screening survey during June 28-29, 2022, in Stockholm, Sweden, to investigate SARS-CoV-2 point prevalence in a group with high exposure risk. Results showed SARS-CoV-2 infection in 2.3% of healthcare workers who were asymptomatic at time of sampling.
