Interesting paper but I'm not convinced that these are asymptomatic cases. I think these are primarily recovered cases that still have trace amounts of non-infectious viral RNA. The originally linked Lancet paper makes a distinction between "viral shedding" and "viral RNA shedding". I think the unanswered question involves individuals in the first week of their newly acquired infection (EDIT: after the incubation period). I hope that doesn't come across as nit picking; the scale and scope of the Wuhan study is impressive but an equivalent study is needed in an area with ongoing community transmission.
