"A 10% prevalence rate on a flight is unbelievably high. Like defies imagination..."
No, it isn't. Past experiments (aimed at measuring the impact of elderberry on cold virus resistance, btw) found about 10% of people on a flight getting infected with a respiratory virus.
It wasn't a coronavirus, but my point is that a respiratory virus spreading to 10% of the people on a flight is so common, the researchers could just pick a normal plane flight and find 10% infection. So, for a virus to spread to 10% of the people on a plane flight is not "unbelievably high", it's apparently not uncommonly seen for other respiratory viruses.
