1) If there is a possibility to infect others after 14 day quarantine, why allow you to move to another hotel? Or. why even allow you to return to your hometown with exposure to the public (by train, plane etc)?
2) So the only sensible thing to do is to put you in quarantine hotel for 21 days. But here is my issue. Almost all COVID infections show symptoms after 4-5 days. Very, very rare case it exceeds 14 days. I feel that recent positive case in Shanghai got infected in quarantine. Not in USA.
Only in China you hear cases after 14, 21 or even 35 days........ Chinese officials and Chinese people want to blame someone. This is beyond absurd.
Not sure why you're confused. You basically answered your own questions.
The +7 exists because the likelihood of infection after 14 days, like you said, is remote. It's a compromise between hardship to the person being quarantined and his risk to the public.
And you know what, I do think there's a possibility that these people were infected during or after quarantine. But most likely from something they brought with them in their suitcase, and not from a source outside of themselves. Again, very low likelihood events.
Only in China do you hear about these outliers because I think other countries would have given up after so many days because they have no ability to determine if it's an infection that occurs afterward due to the presence of locally transmitted disease. In China, there's basically no such local transmission, so that source can be ruled out, relatively.
