Research on IgG seroprevalence among health care workers (HCWs) is needed to re-evaluate health policies. This study was performed in three pandemic hospitals in Istanbul and Kocaeli. Different clusters of HCWs were screened for SARS-CoV-2 infection. Seropositivity rate among participants was evaluated by chemiluminescent microparticle immunoassay. We recruited 813 non-infected and 119 PCR-confirmed infected HCWs. Of the previously undiagnosed HCWs, 22 (2.7%) were seropositive. Seropositivity rates were highest for cleaning staff (6%), physicians (4%), nurses (2.2%) and radiology technicians (1%). Non-pandemic clinic (6.4%) and ICU (4.3%) had the highest prevalence. HCWs in \"high risk\" group had similar seropositivity rate with \"no risk\" group (2.9 vs 3.5 p = 0.7). These findings might lead to the re-evaluation of infection control and transmission dynamics in hospitals.", "doi": "10.1371/journal.pone.0247865", "pmid": "33657142", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC7928442"}, {"db": "pii", "key": "PONE-D-20-35740"}], "notes": [], "created": "2026-08-20T12:44:13.199Z", "modified": "2026-08-20T12:44:13.341Z"}]}
