Contact with secret contacts. Do you need isolation?

Contact with sub-close contacts needs to be isolated.

Close contacts refer to people who have close contact with close contacts, such as living together, working in the same closed environment, dining and entertainment, but have not taken effective protection. Among them, the family members and colleagues of close contacts are the key groups.

According to the relevant regulations, the second close contact person was subjected to centralized isolation medical observation for 7 days. If the COVID-19 nucleic acid test results are negative in the first 7 days, and the COVID-19 nucleic acid test results of its close contacts are also negative, the centralized isolation medical observation will be lifted. The first two nucleic acid tests of close contacts were positive, and the close contacts were managed as close contacts.

Close contact:

Four days before the symptoms of suspected cases and confirmed cases appear, or four days before the samples of asymptomatic infected persons are collected, epidemiological investigation professionals will judge them as close contacts according to epidemiological investigation results and big data information provided by relevant departments.

For example, family members living in the same room, people who have close contact in the same place such as office, workshop, team, elevator, canteen and classroom, people who eat together, entertain together and provide catering and entertainment services in a closed environment, etc. In this regard, disease control experts give examples, such as the whole carriage of high-speed rail, and the three rows of passengers before and after the plane belong to this category.

According to the relevant provisions of the novel coronavirus Prevention and Control Plan (Eighth Edition), the close contacts were subjected to centralized isolation medical observation for 14 days, during 1, 4, 7? And then what? 14 days for nucleic acid detection, 7 days for routine health monitoring after isolation, 2 days and 7 days for nucleic acid detection.

During the daily health monitoring, it is necessary to reduce the flow, do personal protection when going out, and do not participate in gathering activities such as meetings, exhibitions, tours and dinners. In principle, do not leave the county (city, district) before the end of daily health monitoring.
