Is it necessary to isolate the intersection of time and space with a secret connection within an hour?

The intersection of time and space that is secretly connected within one hour needs to be isolated.

After the discovery of sub-secret, centralized isolation medical observation should be carried out within 12 hours. The period of centralized isolation medical observation is determined according to the results of nucleic acid detection of close contacts. For example, the first two nucleic acid tests of close contacts during medical observation were negative.

Second, 1, 4, and 7 days of negative nucleic acid detection can relieve isolated medical observation; Close contacts who have tested positive for nucleic acid twice before shall be managed as close contacts for the second time.

General contact protection process:

General contacts should register and inform health risks. If symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste) and diarrhea occur, they should seek medical advice in time.

When a cluster epidemic occurs in rural areas, and it is difficult for centralized isolation places to meet the needs of centralized isolation in a short time, we can consider taking home medical observation measures for those who are close to each other, strictly closing villages and households during the period, and increasing the frequency of nucleic acid detection.
