Find out the secret connection that can be unsealed

Close contacts take the control measures of "centralized isolation 14 days+home isolation for 7 days", and the home isolation can only be lifted when it reaches 2 1 day.

One is to implement "14+7" health management measures for close contacts, that is, centralized isolation medical observation 14 days, nucleic acid detection for centralized isolation medical observation 1, 3, 7, 14 days, and double collection and double inspection before lifting the isolation (take two samples from the same person and send them. You don't need to go out in principle.

Second, for sub-close contacts, we carried out 7 days of centralized isolation medical observation, and detected the nucleic acid on 1, 3 and 7 days respectively. Before the isolation was lifted, we carried out double sampling and double inspection, and the results were all negative, so we can lift the isolation.
