A question I always have about these studies is at what level symptoms are defined and self-reported. E.g. presumably “you have an itchy throat or a mild headache in the morning/mildly increased fever over your baseline” is pre-symptomatic. Self-isolating with mild symptoms is probably hard to measure but can be at least socially enforced.
