Does the red code nucleic acid test negative still need isolation?
It depends.
There are many reasons why the health code turns red. Whether to isolate the red code personnel with negative nucleic acid test depends on the situation, because the negative results of nucleic acid test can not completely rule out the risk of infection; In addition, there is a certain probability of false negative results in nucleic acid detection. If there is a high-risk group, it needs at least two negative results of nucleic acid test to rule out the possibility of infection, and then the isolation can be lifted. Negative results of nucleic acid test can not be used as a standard for lifting isolation.
For example, if you are a close contact of the confirmed case, if you don't meet 14 days during the isolation period, even if the nucleic acid test is negative, you can't lift the isolation. After the end of the isolation period, it is necessary to test the nucleic acid again. If the result is negative, the isolation can be lifted.
However, if it is a confirmed patient, in addition to the negative nucleic acid test results, it is necessary to meet the cure standard. After reaching the discharge standard, after 14 days of home isolation observation, the possibility of infection can be ruled out, and the negative results of nucleic acid test before this can not be lifted.
Will contact with people in red team become red team?
It's possible.
People with red health code belong to nucleic acid positive, confirmed cases, asymptomatic infected persons, close contacts, sub-close contacts and people who have been to high-risk areas in recent 14 days, and these people belong to high-risk groups. Once diagnosed, people who have had close contact with them will be judged as close contacts or sub-close contacts, and the health code will become red team.
However, if you only have a short contact with people in red team, or the cell phone signal drifts, you may be judged as a space-time companion at this time, and the health code will be given a yellow code, depending on the results of epidemiological investigation. Contact with people in red team may become red team or yellow code.
Do people who come into contact with red team need to be quarantined?
It depends.
The health code is judged according to the personal travel trajectory. If you have been to high-risk areas or had contact with high-risk groups in the past 14 days, the health code will become red team. After the health code becomes red team, you need to report to the local community as soon as possible, and conduct centralized isolation and nucleic acid detection.
Whether people who come into contact with red team will turn red depends on the situation. If they have long-term or close contact, the health code may turn red. However, if it is only short-term contact or time and space overlap, then the health code will turn yellow at this time, depending on the epidemiological investigation.
