I was looking at this paper (for other reasons) and saw that it estimated a mean serial interval of 6.3 days in Shenzhen while there was aggressive testing, contact tracing, and isolating. They report that the mean serial interval was 3.6 days among patients who were infected by someone who was isolated within 2 days of symptom onset, and 8.1 days among patients who were infected by someone who wasn’t isolated until 3+ days after symptom onset, for an overall average serial interval of 6.3 in their population. They found R=0.4 - an average of 0.4 known transmissions from each infected person.
