Community health duties  Among the community managers' duties were to make sure that everyone who was in a public place was wearing a face-mask.  They were also instructed to continuously assess their community's status, including the daily health condition and travel history of every community member.  Managers classified their community members into four groups: of low concern were members who completed the isolation period without any symptoms, of current focus were member still within the isolation period, newly arrived (i.e., today) members from other places should be body temperature tested and closely monitored, and early prevention measures should be taken for the member who arrived recently (i.e., yesterday or earlier) from other places.  During the isolation period, the managers visited their community members and measured their body temperature 3-times a day. If a member's temperature was above the threshold or some typical symptoms of illness occurred, the member was sent to the nearest designated hospital, and the closely contacted members should be homequarantined for further monitoring (e.g., in a Hangzhou city community, a group of 339 managers visited 12025 families in 334 buildings, collected detailed information about them, and 122 disease-related clues were detected for the isolated families).
