In total, 2662 participants were included of whom 7.4% had immunoglobulin G antibodies against SARS-CoV-2. Of the participants reporting a positive polymerase chain reaction for SARS-CoV-2, 89% had antibodies at the time of blood sampling. Eleven per cent of the antibody positive participants reported no recent symptoms suggestive of coronavirus disease 2019 (COVID-19). Participants reporting fever, chest pain and\/or anosmia\/ageusia were significantly more frequently associated with the presence of antibodies against SARS-CoV-2. The presence of antibodies was highest in the group that had had contact with COVID-19-infected individuals outside the hospital with or without using appropriate personnel protective equipment (PPE) (<jats:italic>P<\/jats:italic> &lt; 0.001). Inside the hospital, a statistically significant difference was observed for the employees considered as low-risk exposure compared to the intermediate-risk exposure group (<jats:italic>P<\/jats:italic> = 0.005) as well as the high-risk exposure group compared to the intermediate exposure risk group (<jats:italic>P<\/jats:italic> &lt; 0.001). These findings highlight the importance of using correct PPE.<\/jats:p>","DOI":"10.1017\/s0950268821001540","type":"journal-article","created":{"date-parts":[[2021,7,5]],"date-time":"2021-07-05T10:42:25Z","timestamp":1625481745000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":4,"title":["SARS-CoV-2 seroprevalence among employees of a university hospital in Belgium during the 2020 COVID-19 outbreak (COVEMUZ-study)"],"prefix":"10.1017","volume":"149","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9706-8922","authenticated-orcid":false,"given":"Deborah","family":"De Geyter","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ellen","family":"Vancutsem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sven","family":"Van Laere","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denis","family":"Pi\u00e9rard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Lacor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilse","family":"Weets","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabine D.","family":"Allard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2021,7,5]]},"reference":[{"key":"S0950268821001540_ref4","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1003346"},{"key":"S0950268821001540_ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcv.2020.104437"},{"key":"S0950268821001540_ref24","doi-asserted-by":"publisher","DOI":"10.1093\/cid\/ciab219"},{"key":"S0950268821001540_ref9","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.25727"},{"key":"S0950268821001540_ref15","doi-asserted-by":"publisher","DOI":"10.1136\/thoraxjnl-2020-215414"},{"key":"S0950268821001540_ref23","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiaa659"},{"key":"S0950268821001540_ref18","article-title":"Seroprevalence of IgG antibodies against SARS coronavirus 2 in Belgium -
