The measures of home isolation and continuous health surveillance are generally adopted after the conversion of new crown positives to negatives, subject to the territorial policy. In general, newly crowned infected persons are required to undergo centralized isolation and observation or centralized treatment in designated hospitals. Mild cases can be released from isolation management after two consecutive negative nucleic acid tests with a sampling interval of at least 24 hours. After release from isolation, it is required to continue home health surveillance for 7 days, wear masks, live in well-ventilated single rooms if possible, reduce close proximity and close contact with family members, eat and drink in separate meals, practice good hand hygiene, and avoid going out for activities. However, different regions may have different requirements for people who have become infected, and the local policy should be based on timely cooperation with nucleic acid testing and quarantine measures, and normal social activities can only be carried out after the local conditions for lifting the quarantine have been met.
