    Snippet: The incubation period of a Covid-19 case is the time between infectious exposure and symptom onset. Over 2,000 cases had sufficient information for inferring incubation periods. Most of which had clear records for the dates of exposures and symptom onsets. For imported cases (e.g., travelers from Wuhan city), the exposure dates were defined as the dates of leaving the epicentral cities such as Wuhan. For the cases, who had been quarantined and mo.....
    Document: The incubation period of a Covid-19 case is the time between infectious exposure and symptom onset. Over 2,000 cases had sufficient information for inferring incubation periods. Most of which had clear records for the dates of exposures and symptom onsets. For imported cases (e.g., travelers from Wuhan city), the exposure dates were defined as the dates of leaving the epicentral cities such as Wuhan. For the cases, who had been quarantined and monitored for the disease, the diagnosed dates were set as the dates for their symptom onsets. χ2 tests and t-tests were used for statistical analysis using R, a free software environment for statistical computing. We considered p values of less than 0.05 to be significant.
