is the (which was not peer-reviewed) The copyright holder for this preprint we read the case reports in Chinese to curate age, sex, demographic information (i.e., name of the provinces and cities), dates of exposures, symptom onset and diagnosis (i.e., confirmed the SARS-CoV-2 infection through laboratory-tests), when available. The patient data were curated by XJ, WXC, and YCC who are native Chinese speakers and translated the summary of each patient into English. To make sure the data accuracy, the curations have been cleaned and checked 4 times by four other researchers, YWN, XL, LL, and EW. We mainly focused on the cases which were allowed to inferring incubation time. Among 4567 cases, after removing the cases which did not have exposure dates, or whose exposure dates were not sure, we obtained 2015 cases whose incubation times could be inferred. Because the information of Covid-19 cases in Hubei province including Wuhan, the city at the center of the epidemic, was not publicly available, this cohort included only non-Hubei cases.
