The global pandemic of 2019 coronavirus disease(COVID-19)is a great assault to public *** transmission cannot be controlled with measures designed for symptomatic persons,such as *** study aimed to estimate the interval of the transmission generation(TG)and the presymptomatic period of COVID-19,and compare the ftting effects of TG and serial interval(S)based on the SEIHR model incorporating the surveillance data of 3453 cases in 31 *** data were allocated into three distributions and the value of AIC presented that the Weibull distribution fitted *** mean of TG was 5.2 days(95%C:4.6-5.8).The mean of the presymptomatic period was 2.4 days(95%CI:1.5-3.2).The dynamic model using TG as the generation time performed *** provinces exhibited a basic reproduction number from 2.16 to *** should be taken to control presymptomatic transmission in the COVID-19 pandemic.
