Model fitting results and model predictions of the cumulative number of cases under different scenarios. Model results (red line) and observations (black dots; A). Cumulative number of cases resulting from different incubation periods (B, range 5–25 days), isolation times (C, range 14–28 days), effectiveness of comprehensive quarantine measures (D, range 0.8–1.2 times of the initial values), and effectiveness of nucleic acid testing (E, range 0.8–1.2 times of the initial values). F–K show the cumulative number of cases under different combination of incubation period (5–28 days), isolation period (14–28 days) and effectiveness of comprehensive quarantine measures (0.8–1.2 times of the initial values) and effectiveness of nucleic acid detection (0.8–1.2 times of the initial values). Solid black lines in F–K are isopleths corresponding to 869 cases
