T57 0-133 Sentence denotes Following previous studies (Zhao et al., 2019, de Silva et al., 2009), we modelled the epidemic curve obeying the exponential growth.
T58 134-230 Sentence denotes The nonlinear least square (NLS) framework is adopted for data fitting and parameter estimation.
T59 231-430 Sentence denotes The intrinsic growth rate (γ) of the exponential growth was estimated, and the basic reproduction number could be obtained by R 0 = 1/M(−γ) with 100% susceptibility for 2019-nCoV at this early stage.
T60 431-676 Sentence denotes The function M(∙) is the Laplace transform, i.e., the moment generating function, of the probability distribution for the serial interval (SI) of the disease (Zhao et al., 2019, Wallinga and Lipsitch, 2007), denoted by h(k) and k is the mean SI.
T61 677-830 Sentence denotes Since the transmission chain of 2019-nCoV remains unclear, we adopted the SI information from SARS and MERS, which share a similar pathogen as 2019-nCoV.
T62 831-1113 Sentence denotes We modelled h(k) as Gamma distributions with a mean of 7.6 days and standard deviation (SD) of 3.4 days for MERS (Assiri et al., 2013), and mean of 8.4 days and SD of 3.8 days for SARS (Lipsitch et al., 2003) as well as their average, see the row heads in Table 1 for each scenario.
T63 1114-1214 Sentence denotes Table 1 The summary table of the estimated basic reproduction number, R0, under different scenarios.
T64 1215-1275 Sentence denotes The estimated R0 is shown as in the ‘median (95%CI)’ format.
T65 1276-1491 Sentence denotes The ‘reporting rate increased’ indicates the number of fold increase in the reporting rate from January 17, when WHO released the official diagnostic protocol (World Health Organization, 2020b), to January 20, 2020.
T66 1492-1529 Sentence denotes Reporting rate increased Estimated R0
T67 1530-1605 Sentence denotes Same as MERS SI 7.6 ± 3.4 SI in average 8.0 ± 3.6 Same as SARS SI 8.4 ± 3.8
T68 1606-1668 Sentence denotes (unchanged) 5.31 (3.99–6.96) 5.71 (4.24–7.54) 6.11 (4.51–8.16)
T69 1669-1728 Sentence denotes 0.5-fold 4.52 (3.49–5.76) 4.82 (3.69–6.20) 5.14 (3.90–6.67)
T70 1729-1786 Sentence denotes 1-fold 4.01 (3.17–5.02) 4.26 (3.34–5.38) 4.53 (3.51–5.76)
T71 1787-1844 Sentence denotes 2-fold 3.38 (2.75–4.12) 3.58 (2.89–4.39) 3.77 (3.02–4.67)
T72 1845-1902 Sentence denotes 4-fold 2.73 (2.31–3.22) 2.86 (2.40–3.39) 3.00 (2.50–3.58)
T73 1903-1960 Sentence denotes 8-fold 2.16 (1.90–2.45) 2.24 (1.96–2.55) 2.32 (2.02–2.66)
T74 1961-2088 Sentence denotes Note: ‘SI’ is serial interval. ‘MERS’ is Middle East Respiratory Syndrome, and ‘SARS’ is the Severe Acute Respiratory Syndrome.
