Strengths and Limitations
The peak of the epidemic will eventually pass and preventing the repeated outbreaks is our common goal. This is the first study which focused on the optimized screening procedure to avoid hospital infections after the peak of the COVID-19 outbreak in obstetrics and gynecology outpatient. There are some limitations. First, the sample size of outpatients was relatively small. Second, for positive IgM test, quantitative tests should also be conducted to dynamically observe the changes in its level. Third, for patients with IgM positive, we should extend the follow-up time.
