ABSTRACT
Objectives:
The COVID-19 has been the public health issues of global concern, but the incubation period was still under discussion. This study aimed to estimate the incubation period distribution of COVID-19.Methods:
The exposure and onset information of COVID-19 cases were collected from the official information platform of provincial or municipal health commissions. The distribution of COVID-19 incubation period was estimated based on the Log- normal, Gamma and Weibull distribution by interval-censored data estimation method.Results:
A total of 109 confirmed cases were collected, with an average age of 39.825 years. The median COVID-19 incubation period based on Log-normal, Gamma, and Weibull distribution were 4.958 (P(25)-P(75) 3.472-7.318) days, 5.083 (P(25)-P(75) 3.511-7.314) days, and 5.695 (P(25)-P(75) 3.675-7.674) days, respectively. Gamma distribution had the largest log-likelihood result.Conclusions:
The distribution of COVID-19 incubation period followed the Gamma distribution, and the interval-censored data estimation method can be used to estimate the incubation period distribution.Key words
