Many studies had evaluated the seroprevalence among HCWs (Steensels et al., 2020; Martin et al., 2020; Korth et al., 2020; Stubblefield et al., 2020; Pallett et al., 2020; Grant et al., 2020; Hunter et al., 2020; Self et al., 2020; Moscola et al., 2020; Plebani et al., 2020 HCWs who regularly had direct contact with units housing adult COVID-19 patients in the month prior to undergoing testing with the validated enzyme-linked immunosorbent assay against the extracellular domain of the SARS-CoV-2 spike protein (Stubblefield et al., 2020) . These findings may be due to the fact that anti-SARS-CoV-2 antibody seroprevalence varies according to the different study countries/regions, study populations, timing during the period of the COVID-19 pandemic, and methods used for serology tests.	./cache/cord-305763-160heazx.txt	./txt/cord-305763-160heazx.txt
