Methods: We enrolled 4927 health care personnel working in pediatric units at 32 hospitals from 7 different regions of Turkey in a study to determine SARS Co-V-2 seroprevalence after the first peak of the COVID-19 pandemic. A point of care serologic lateral flow rapid test kit for immunoglobulin (Ig)M/IgG was used. Seroprevalence and its association with demographic characteristics and possible risk factors were analyzed. Results: SARS-CoV-2 seropositivity prevalence in health care personnel tested was 6.1%. Seropositivity was more common among those who did not universally wear protective masks (10.6% vs 6.1%). Having a COVID-19-positive co-worker increased the likelihood of infection. The least and the most experienced personnel were more likely to be infected. Most of the seropositive health care personnel (68.0%) did not suspect that they had previously had COVID-19. Conclusions: Health surveillance for health care personnel involving routine point-of-care nucleic acid testing and monitoring personal protective equipment adherence are suggested as important strategies to protect health care personnel from COVID-19 and reduce nosocomial SARS-CoV-2 transmission. © 2021 The Author(s)EnglishAll Open Access; Gold Open AccessAntibodies, ViralChildCOVID-19Delivery of Health CareHealth PersonnelHumansPandemicsSARS-CoV-2Seroepidemiologic StudiesTurkeyimmunoglobulin Gimmunoglobulin MSARS-CoV-2 antibodyvirus antibodyadultagedArticlechild health carecoronavirus disease 2019COVID-19 nucleic acid testingcoworkercross-sectional studydemographyfemalegeographic distributionhealth care personnelhealth surveyhumanmajor clinical studymalemonitoringnonhumannursepandemicpediatric wardphysicianpoint of care testingrisk factorseroprevalenceSevere acute respiratory syndrome coronavirus 2Turkey (republic)childepidemiologyhealth care deliveryhealth care personnelseroepidemiologyturkey (bird)Article10.1016/j.ijid.2021.09.054
