Physiological anomaly rate curves in Wuhan aligned by the time of Chinese Spring Festival. The two grey curves and the blue curve represent the physiological anomaly rate calculated by the anomaly detection algorithm from 2018 to 2020, respectively. The purple curve and the red curve represent the predicted physiological anomaly rate with and without the supervision of the official data, respectively.
