±×¸² 1) Cumulative distribution function of the COVID-19 incubation period estimate from the log-normal model.[ The estimated median incubation period of COVID-19 was 5.1 days (CI, 4.5 to 5.8 days). We estimated that fewer than 2.5% of infected persons will display symptoms within 2.2 days (CI, 1.8 to 2.9 days) of exposure, whereas symptom onset will occur within 11.5 days (CI, 8.2 to 15.6 days) for 97.5% of infected persons. Horizontal bars represent the 95% CIs of the 2.5th, 50th, and 97.5th percentiles of the incubation period distribution. The estimate of the dispersion parameter is 1.52 (CI, 1.32 to 1.72).

Ç¥ 1) Percentiles of SRRS-CoV-2 Incubation Period from Selected Sensitivity Analyses

SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2. * Using the log-normal model, we estimated the incubation period for several subsets. The first analysis looked at time to fever onset, as opposed to time to first symptom onset as used in the main analysis. The second and third analyses estimated the incubation period for cases outside and within mainland China, respectively. To test the effect of our assumption that the exposure window for Wuhan residents started on 1 December 2019, we used an extreme assumption that the exposure window instead started on 1 December 2018 (EL-2018) and found little change in our estimates.
