Centralized isolation means one person and one room. Centralized isolation refers to the centralized isolation observation of people who have been to virus-infected areas or have close contact with virus-infected people, and only one person can be in one room during the isolation period, so that safety investigation can be carried out more accurately.
When being isolated, if it is not isolated by one person and one room, and the isolated person has had physical contact, there is no need for isolation. During the isolation period, the isolated person should be isolated in strict accordance with the isolation standards and actively cooperate with the isolation work to make the isolation work effective.
