Case	Sex	Age, years	Symptomatic status	Day of follow-up (n)		Frequency of specimen (n)			Detectable duration of viral shedding (days)		Observed on the last day (after the last exposure) of viral shedding
				Respiratory tract specimen	Faecal specimen	Subtotal	Respiratory tract specimen	Faecal specimen	Respiratory tract specimen	Faecal specimen	Respiratory tract specimen	Faecal specimen
Case 01^	Male	42	Symptomatic	39	26	23	16	7	33	1	45	26

Duration of viral shedding is calculated as the time lag from the first to the last day when the cycle threshold (Ct) value of the ORF1ab or N region was <40.

Note: NE, molecular diagnosis result is negative.

*, patient was discharged from the hospital with a positive faecal specimen and isolated in a designated setting.

^{^}, patient with recurrent positive results in respiratory tract specimens after discharge.
