Document: In the current investigation we included only those COVID-19 patients who stayed in Hubei for at most two calendar days. The day of exposure was taken as the first day to Hubei if the patient stayed in Hubei for one calendar day; or 20 as the middle of the first and second day in Hubei if the patient stayed for two calendar days. By excluding COVID-19 patients who stayed in Hubei for more than two days, one can better define the the day of exposure. The incubation period for each COVID-19 patient is inferred as the number of days between exposure and symptom onset. 25
