    Asymptomatic carriers, known as SARS-CoV-2, tested positive, but had no corresponding clinical symptoms, and this group could be a potential source of infection.
    study aims to identify the epidemiological and impact factors of asymptomatic carriers in the general population.
    at Wuhan University Central South Hospital, all hospital staff received pharynx RT-PCR testing, plasma COVID-19 IgM/IgG antibody testing and chest CT scans.
    researchers analyzed the correlation between infection rates and employee gender, age, job title, workplace, and COVID-19 knowledge training.
    all asymptomatic infections are retested once a week for 3 consecutive weeks.
    (research flowchart) of the hospital, a total of 3,764 hospital staff were included in the single-center cross-sectional study.
    , 126 hospital staff had abnormal results and the asymptomatic infection rate was 0.76% (28/3674).
    26 employees of the IgM positive , 73 bits of IgG , 40 of the chest CT examination has a grinding glass shadow.
    (positive for three tests) all workers found abnormalities, the older they were, the more likely they were to be abnormal and not affected by gender.
    of the 3,674 employees, the positive rate of front-line staff was significantly higher than that of health section staff (HCW) and administrative staff.
    there was no statistically significant difference in the positive rate between high-risk and low-risk departments during the treatment of COVID-19.
    of health care workers who participated in COVID-19 knowledge training were lower than those who did not attend early training.
    (IgM/IgG titration for non-infected, asymptomatic infections, confirmed patients) is that there is no statistical difference between the IgM antibody titration of asymptomatic infections and those diagnosed with COVID-19 in the recovery phase.
    during the 3-week follow-up process, all asymptomatic infected people did not show clinical symptoms or imaging abnormalities without active intervention at the isolation point.
    (Lung Grinding Glass Shadow) Summary: In order to ensure the safety of resumption of work, the organization should provide COVID-19 prevention training to employees and screen for asymptomatic infections, and take appropriate isolation measures in densely populated areas.
