Oh. The surprise was that the relative viral load while asymptomatic was higher than expected, i.e., the symptoms start later than would normally be expected.
Essentially, this is *different* than the flu, and probably the best lay explainer graphic I've seen is this one:
"Presymptomatic transmission of influenza has been inferred based on the presence of the virus in the upper respiratory tract rather than from appropriate transmission experiments. This is troubling because our review of the literature does not support significant influenza transmission based on positive nasopharyngeal cultures in the absence of symptoms." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2646474/
However, it's fairly clear, based on all the data being tracked, that asymptomatic transmission is significant in SARS-CoV-2, and the current hypothesis is that the incubation period is 4-14 days, perhaps longer.

Right, and I've been having to brush up on my v. rusty immunology to even understand some of the conversations I've been reading. As I've whimpered before, the problem with immunology papers is that they're not written in English even when they are.
