• A single-center cross-sectional study of hospital staff in Wuhan, China tested all staff members who did not have clinical symptoms of COVID-19 (n=3,764) and found that 126 (3%) hospital staff had findings consistent with SARS-CoV-2 infection. These included 61 (2%) with anti-SARS-CoV-2 IgG antibodies, 37 (1%) with chest CT findings consistent with COVID-19, and 28 (0.7%) with anti-SARS-CoV-2 IgM or positive PCR. There was no statistical difference between the titers of IgM antibody of participants with asymptomatic infections and confirmed patients with COVID-19 in recovery period.
