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.
Matters needing attention
Red team will not turn green without nucleic acid.
Generally speaking, after the health code turns red, it is necessary to carry out centralized isolation medical observation and perform nucleic acid detection according to the prescribed frequency. Only when the isolation period expires and the nucleic acid test result is negative can red team be released and become a green code.
If you don't do nucleic acid detection, the red code will not automatically change back to the green code, because the risk of contact and infection of the red code is high, so you need to do nucleic acid detection and isolation observation for further investigation and confirmation.
