    Document: We retrieve the data from the Chinese media conglomerate Tencent (Chinese National Health Commission); however, the data show small differences in case counts compared to data of the epidemic reported by other sources (Johns Hopkins University Center for Systems Science and Engineering, 2020). Importantly, the curves of confirmed cases that we employ in our study are reported according to reporting date and could be influenced by testing capacity and other related factors. Further, there may be significant delays in identifying, isolating, and reporting cases in Hubei due to the magnitude of the epidemic, which could influence our predictions. Incidence curves according to the date of symptom onset could provide a clearer picture of the transmission dynamics during an epidemic. We also note that we analyzed the epidemic curves starting on January 22, 2020, but the epidemic started in December 2019. Hence, the first data point accumulates cases up until January 22, 2020, as data were not available prior to this date.
