1, the abnormal nucleic acid detection may be that the mixed nucleic acid test result is positive, and it needs to be rechecked to show that the result is abnormal; Or the nucleic acid test result is suspected to be false positive, and the health code will turn red because the first result is nucleic acid positive.
2. However, if the test result of nucleic acid is negative, and the abnormality of nucleic acid is a false negative caused by sampling samples or a false negative caused by nucleic acid sample pollution, the health code will not change color, and it is still a green code.
How long does it take for the health code to turn red and green? After completing the specified number of nucleic acid tests and corresponding isolation days, if it is determined that there is no risk of COVID-19 infection, it can be turned into a green code.
For those who have positive nucleic acid test, confirmed cases, asymptomatic infected persons, suspected cases, close contacts of close contacts, close contacts of close contacts, entry personnel, and those who have lived in medium and high-risk areas in China in the past 14 days, the health code is changed to red, which belongs to the high-risk situation of suspected COVID-19 infection. If you want to restore the green code, you need to judge that there is no risk of COVID-19.
No infection is based on the new negative result of nucleic acid, no symptoms of COVID-19 infection, normal detection and normal signs during isolation. Therefore, according to the needs of the epidemic prevention department, after the specified number of nucleic acid tests and at least two negative results of nucleic acid are completed, the corresponding isolation days are 14 days and 7 days. If the specific days are uncertain, it can be determined that the individual has no risk of COVID-19 infection and can be turned into a green code.
3. If all employees don't do nucleic acid testing, will the health code turn red? The health code may turn red, yellow or gray.
At present, according to the regulations of local epidemic prevention departments, full-time nucleic acid testing should be done, but those who fail to cooperate with nucleic acid sampling on time will be given red, yellow or gray health codes. For example, those who do not participate in full-time nucleic acid testing in Fujian will be marked as "yellow code"; If you don't participate in full-time nucleic acid testing for two consecutive rounds, "Fujian Health Code" will be marked as "red code"
Zhejiang gives a gray code.
Because nucleic acid detection can effectively screen potential infected people, it is an important measure for epidemic prevention and control. Through nucleic acid detection, risk areas and key populations can be locked, and targeted control measures can be taken in time to stop the spread of the epidemic. Therefore, residents are requested to complete sampling in an orderly manner under the arrangement of local streets (towns) and communities (villages) to avoid discoloration of health codes.
4 When will the health code change color 1? Residents in fixed risk areas: residents in high risk areas are red, residents in medium risk areas are yellow, and residents in low risk areas are green.
2. Low-risk residents go to high-risk and medium-risk areas: those with green codes enter high-risk and medium-risk areas, wait 1 hour and the health code will automatically turn red and yellow after the mobile phone is turned on.
3. Medium-risk residents go to low-risk areas: From the arrival time, the first 2 1 day is yellow code, and after 2 1 day, the normal results of nucleic acid test are uploaded and turn green. Those who have not uploaded will always be in a yellow code state.
4. High-risk residents go to low-risk areas: from the arrival time, the first 14 days is red team, and the last 7 days are yellow codes. After 2 1 day, the normal results of nucleic acid detection were uploaded and turned green. Those who have not uploaded will always be in a yellow code state.
5. Overseas personnel: From the time of arrival, the code is yellow for the first 28 days, and after 28 days, the normal results of nucleic acid test are uploaded and turn green. Those who have not uploaded will always be in a yellow code state.
6, nucleic acid test positive, had a history of contact with COVID-19 confirmed cases or asymptomatic infected people, including close contacts, close contacts, and close contacts with red team time and space.
7. The information reported when the health code is declared is not accurately assigned with yellow code or red team.
