T166 1269-1449 Sentence denotes The set of S, E, I, R, σ, and γ is the same as the first section except that we also explored the model with E at 30 times of I to provide a possible range of number of infections.

T171 1771-1949 Sentence denotes The first phase ranges from 1 December 2019 to 23 January 2020 and can be regarded as the early phase of the epidemic when a few prevention and control measures were implemented.
T172 1950-2037 Sentence denotes R0 was set as 3.1 consistent with Imai et al.’s9 estimation of high transmission level.
T173 2038-2254 Sentence denotes On 23 January 2020, airplanes, trains, and other public transportation within the city were restricted and other prevention and control measures such as quarantine and isolation were gradually established in Wuhan20.

T180 2953-3206 Sentence denotes So, the last phase began on 16 February and Rt was set as 0.9 and 0.5, respectively, assuming the prevention and control measures are sufficient and effective to depict two different levels of effect of the measures in reducing transmission probability.
