Not sure why the "playing doctor or evolutionary biologist" is pertinent here. Seems unnecessary.
Here's the passage I found interesting:
"The researchers found very high levels of virus emitted from the throat of patients from the earliest point in their illness —when people are generally still going about their daily routines. Viral shedding dropped after day 5 in all but two of the patients, who had more serious illness. The two, who developed early signs of pneumonia, continued to shed high levels of virus from the throat until about day 10 or 11.
This pattern of virus shedding is a marked departure from what was seen with the SARS coronavirus, which ignited an outbreak in 2002-2003. With that disease, peak shedding of virus occurred later, when the virus had moved into the deep lungs.
Shedding from the upper airways early in infection makes for a virus that is much harder to contain."
Completely agree about the not-yet-peer-reviewed caution, as well as the small numbers in the study.

THat is so anecdotal and small sample and unreliable and unreviewed. But I agree it is interesting. Would be nice to find something more robust on the point to really question the more common evidence that transmissible viral shedding and symptoms start roughly at the same time.
