In the process of life, study, work and diagnosis and treatment, people who have been in contact with suspected cases, confirmed cases and asymptomatic infected people on the same means of transportation such as airplanes, trains and ships, as well as people who have been in contact with public places such as shopping malls, farmers' markets, bus stops and subways, generally do not need to be isolated because they have not yet reached the principle of judging close contacts.
Disease control experts suggest that the general contact population of close contacts should be registered to inform health risks and minimize aggregation activities. Once you have symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea, etc., you should seek medical advice in time and take the initiative to inform your contact history.
What is the difference between close contact and sub-close contact? Close contacts refer to people who had close contact with suspected cases and confirmed cases two days before symptoms appeared (extended to the first four days according to the actual situation in some areas) or two days before asymptomatic infected persons were sampled, but did not take effective protection.
According to the relevant epidemic prevention requirements, the close contacts were observed 14 days. During this period, nucleic acid tests will be conducted on 1, 4, 7 and 14 respectively, and daily health monitoring will be conducted on the 7th day after the isolation, and nucleic acid tests will be conducted on the 2nd and 7th days respectively.
Sub-close contacts are mainly people who are in close contact with their families and colleagues. The time limit for centralized isolation medical observation of sub-close contacts is determined according to the results of nucleic acid detection of close contacts.
If the first two nucleic acid tests of the close contact were negative during the isolation medical observation period, and the nucleic acid tests of the sub-close contact were negative on 1, 4 and 7 days, the sub-close contact can be released from the isolation medical observation on the 7th day; If the previous two nucleic acid tests of close contacts are positive, the second close contact will be managed as a close contact until the expiration of 14 days.
How does the secret receiver judge? 1. Family members living in the same room.
2. Direct caregivers or providers of medical and nursing services.
3. Medical personnel who may carry out aerosol diagnosis and treatment activities in the same space.
4. In offices, workshops, teams, elevators, canteens, classrooms and other places that have close contact with people.

8. Persons exposed to the environment and articles contaminated by cases or asymptomatic infected persons.
9. On-site investigators evaluate other personnel who meet the criteria for judging close contacts.
What color is the health code of the secret connector? Red team.
Generally, the health code of people who receive centralized or isolated medical observation and management at home is red. This group includes those who are positive for nucleic acid detection, confirmed cases, asymptomatic infected persons, suspected cases, close contacts of close contacts, entry personnel, and those who have lived in China's medium and high-risk areas in the past 14 days. At the same time, the health codes of other high-risk personnel who need emergency tracking and isolation management are also red.
