This study investigated the rates of previous COVID-19 among HCWs in nursing homes, hospitals and a municipal emergency room (ER). Methods: We prospectively included 747 HCWs: 313 from nursing homes, 394 from hospitals and 40 from the ER. The diagnosis of COVID-19 was based on serological evidence of SARS-CoV-2 antibody positivity and self-reported RT-PCR positivity prior to inclusion. Information regarding age, sex and exposure to SARS-CoV-2 infection was collected. Results: A total of 4% (11\/313) of nursing home HCWs and 6% (28\/434) of HCWs in hospitals\/the ER tested positive by serology and\/or RT-PCR (p = 0.095). Fewer HCWs in nursing homes had occupational exposure to SARS-CoV-2 compared to those in hospitals\/the ER (16% vs. 48%, p &lt; 0, 001), but nursing homes had a higher proportion of HCWs with occupational exposure using partial\/no PPE (56% vs. 19%, p &lt; 0.001). Nevertheless, no significant differences in the risk for COVID-19 were found in relation to the rate of occupational exposure (p = 0.755) or use of inadequate PPE (p = 0.631). Conclusions: Despite a small sample size, the risk for COVID-19 among HCWs did not appear to be related to the type of health care facility, rates of occupational exposure or use of PPE.<\/jats:p>","DOI":"10.3390\/v14122652","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T04:31:16Z","timestamp":1669609876000},"page":"2652","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["SARS CoV-2 Infection among Health Care Workers from Different Health Care Facilities in Western Norway: A Prospective, Cross-Sectional Study"],"prefix":"10.3390","volume":"14","author":[{"given":"B\u00e5rd Reiakvam","family":"Kittang","sequence":"first","affiliation":[{"name":"Department of Nursing Home Medicine, Municipality of Bergen, 5020 Bergen, Norway"},{"name":"Department of Clinical Science, University of Bergen, 5007 Bergen, Norway"},{"name":"Department of Medicine, Haraldsplass Deaconess Hospital, 5009 Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bj\u00f8rn","family":"Blomberg","sequence":"additional","affiliation":[{"name":"Department of Clinical Science, University of Bergen, 5007 Bergen, Norway"},{"name":"Department of Medicine, Haukeland University Hospital, 5021 Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4670-4957","authenticated-orcid":false,"given":"Marianne","family":"S\u00e6vik","sequence":"additional","affiliation":[{"name":"Department of Medicine, Haukeland University Hospital, 5021 Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9772-4923","authenticated-orcid":false,"given":"Jan Stefan","family":"Olofsson","sequence":"additional","affiliation":[{"name":"Influenza Centre, Department of Clinical Science, University of Bergen, 5007 Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Bergen COVID-19 Research Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nina","family":"Langeland","sequence":"additional","affiliation":[{"name":"Department of Clinical Science, University of Bergen, 5007 Bergen, Norway"},{"name":"Department of Medicine, Haukeland University Hospital, 5021 Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8341-4078","authenticated-orcid":false,"given":"Rebecca Jane","family":"Cox","sequence":"additional","affiliation":[{"name":"Influenza Centre, Department of Clinical Science, University of Bergen, 5007 Bergen, Norway"},{"name":"Department of Microbiology, Haukeland University Hospital, 5021 Bergen, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"212","DOI":"10.1017\/ice.2020.402","article-title":"Seroprevalence of SARS-CoV-2 antibodies in healthcare workers at a London NHS Trust","volume":"42","author":"Grant","year":"2021","journal-title":"Infect.
