Certainly not, although I may have done a poor job explaining my point. I was simply trying to say that people do not need to be quarantined unless they have a reasonable chance of being contagious at the time.
The question was triggered by a discussion about when people become contagious.
The official line is that people are not contagious until they become symptomatic. However, if the "authorities" truly believe people are not contagious until they are symptomatic, then why quarantine people immediately?
My personal opinion is that the "authorities" suspect a person may become contagious before they are symptomatic, but that they are worried about the public reaction if they say so. Hence they are using a quarantine protocol that implies they think you may be contagious before symptoms develop, but telling the public not to worry.
That line of thinking led me to question why the U.S. is following a different quarantine protocol.
