                    Snippet: We acknowledge four main limitations of our systematic review. First, our findings are mainly 275 based on studies that recruited patient from clinics and hospitals and so may be biased 276 toward more severe cases. Second, many studies did not report the study outcomes by 277 subgroups such as age or gender and so we could report group-specific outcomes. Third, we 278 used the mean and the standard error of the incubation period assuming a norma.....

Third, we 278 used the mean and the standard error of the incubation period assuming a normal 279 distribution which may have led to underestimate the right tail of the distribution. Lastly, 280
