a, Schematic of the relation between different time periods in the transmission of infectious disease. b, Human-to-human transmission pairs of SAR-CoV-2 virus (N = 77). We assumed a maximum exposure window of 21 days prior to symptom onset of the secondary cases. Detailed information on the transmission pairs and the source of information is summarized in Supplementary Tables 2 and 3. c, Estimated serial interval distribution (top), inferred infectiousness profile (middle) and assumed incubation period (bottom) of COVID-19.
