Parents did not receive the quarantined mail.

Parents didn't receive a reply to the quarantine message: this question seems to be wrong. It is very important to isolate the epidemic situation in COVID-19. After investigation, the community network administrator should call the parties, and if the situation is serious, the police should cooperate with the isolation management! Parents do not need to be quarantined if they do not receive the quarantined mail. As far as I know, epidemic isolation is not a short message notification, at least not a telephone notification!
