SARS-CoV-2 detection and testing

Objectives: To examine seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in industry workers population sample. Methods: From 23 to April 28, 2020, we conducted serological testing for antibodies (Immunoglobulin G (IgG) and Immunoglobulin M (IgM)) on 1494 factory employees living in the Split-Dalmatia and Šibenik-Knin County (Croatia). Results: We detected antibodies in 1.27% of participants (95% confidence interval [CI] 0.77–1.98%). In Split facility 13/1316 (0.99%, 95% CI 0.53–1.68%) of participants were tested positive, of which 13/1079 (1.20%, 95% CI 0.64–2.05%) of those living outside the facility and 0/237 (0%, 95% CI 0–1.26%) of those living inside the facility. In Knin facility, 6/178 (3.37%, 95% CI 1.25–7.19%) participants were tested positive for antibodies. Conclusions: The study showed relatively small SARS-CoV-2 antibody seroprevalence in the DIV Group population sample.
