(Color online) Value of $R˜0(t)$ estimated by the stage-rolling SEIR model. (a–c) $R˜0(t)$ of the whole country, the whole country except Hubei Province, the whole country except Wuhan city, respectively. (d–f) Plot the number of newly confirmed cases per day in the whole country, the whole country except Hubei Province and the whole country except Wuhan city, respectively

(Color online) True and predicted values of $R˜0(t)$ in the country except Hubei Province. The solid circle symbols denote the ture value and the hollow diamond symbols denote the predicted one

(Color online) Predicted numer of COVID-19 infections. The circles are the true values while other symbols are the predicted values. (a) and (b) Predicted values in the whole country except Hubei Province; (c) and (d) predicted values in the whole country except Wuhan city; (e) and (f) predicted values in the Hubei Province except Wuhan city

(a–c) Present the number of cases in the whole country except Hubei Province, the whole country except Wuhan city and the Hubei Province except Wuhan city, respectively. The relationship between $R˜0(t)$ and fitted slope is described in Eqs. (11) and (12)
