No, the reverse. The spokesperson said the sick person shouldn’t be in crowds for too long.

Well, yes, of course. I was writing about something different: the long-term exposure when a person is healthy to minuscule bits of infective material from all kinds of interactions, not just crowds.

It’s well known to be true.

A nun was once isolated for too long as a punishment and when she returned to the abbey main population she immediately became ill and died.

Except, really, the sick person shouldn't be in crowds AT ALL. Or in uncrowded places. They should be staying home for the duration of the self-isolation/quarantine. There is no "Oh, well go out when it's not busy only", at that point the self-quarantine is broken anyway.
