Six articles were identified and included in this review (Table 2) [2,8-12] . Four relevant studies estimated the reproductive number [8,10-12]. A study of confirmed cases from Wuhan, China estimated the reproductive number to be 1.9 (95% confidence interval [CI], 1.3 to 3.2) [10]. Three other studies estimated the mean reproductive number as 0.3, 2.2, and 2.68, respectively [8,11,12]. A study reported the mean incubation period to be 6.1 days (95% CI, 3.8 to 9.7), and the mean serial interval to be 7.7 days (95% CI, 4.9 to 13.0) [10]. Two studies predicted the mean doubling time to be between 6.4 days and 8.7 days [10,11]. Three studies estimated the fatality rate of hospitalized cases as 14-15% [2,8,9]. We could not identify any studies that reported the infectious and latent periods.
