Basic Reproduction Number of the 2019 Novel Coronavirus Disease in the Major Endemic Areas of China: A Latent Profile Analysis.

ABSTRACT: Objective: The aim of this study is to analyze the latent class of basic reproduction number (R ₀) trends of the 2019 novel coronavirus disease (COVID-19) in the major endemic areas of China. Methods: The provinces that reported more than 500 cases of COVID-19 till February 18, 2020 were selected as the major endemic areas. The Verhulst model was used to fit the growth rate of cumulative confirmed cases. The R ₀ of COVID-19 was calculated using the parameters of severe acute respiratory syndrome (SARS) and COVID-19. The latent class of R ₀ was analyzed using the latent profile analysis (LPA) model. Results: The median R ₀ calculated from the SARS and COVID-19 parameters were 1.84-3.18 and 1.74-2.91
