Close contact refers to close contact. This kind of population refers to the people who had close contact with the confirmed cases, suspected cases and asymptomatic infected persons four days before their symptoms appeared, or two days before the asymptomatic infected persons were sampled, but did not take effective protection.
According to epidemic regulations, confirmed cases, suspected cases, asymptomatic infected persons, their close contacts and sub-close contacts will be given red team, so in summary, we can know that the health code of close contacts is red team.
If there are high-risk contacts, such as living in a middle-high risk area in the past 14 days, or having been in contact with confirmed cases, suspected patients and asymptomatic infected people, resulting in close contacts or sub-close contacts, the health code will be given to red team, and then the health code of people who live, live or work with it will become red team. According to the results of epidemiological investigation, contact with people in red team may also turn into a yellow code. It is suggested that the health code be isolated to the local community and village committee as soon as possible after it becomes discolored. If necessary, it is suggested to isolate it according to the regulations.
If the health code changes from green code to red code, it needs to be reported to the community (village), unit or hotel. The first time, and cooperate with the implementation of nucleic acid detection, isolation control and health monitoring and other prevention and control measures; Among them, red team personnel need to undergo centralized isolation medical observation 14 days. If the nucleic acid test results are all negative, the isolation can only be lifted after the health declaration is normal.
