You changed your personal information in the public security organs, but did not change it in time; your identity information is not uploaded to the public security organs network verification system, the public security organs network verification is not available, and other circumstances; health code failure caused by the interruption of the continuous filling of records is expected to flights can not be expected to reach the number of days before the flight takes off to fill in a continuous number of days;

For the convenience of travelers to understand in a timely manner the health filling of the situation may be The impact on the trip, once the monitoring of the specified situation, the small program will display the trip risk reminder, for travelers to grasp at any time, and accordingly make adjustments to the trip; it may be that the big data detected that you passed by the epidemic area or stayed in the epidemic area. The application of health code covers the community, catering, hotel, school, medical, shopping, cultural tourism, production and processing, transportation and travel, office buildings and other use scenarios to assist the staff of the communities, companies, superstores and other staff to do a good job in epidemic prevention, control and management. Health code color change rules, high-risk area residents for red, medium-risk areas for yellow, low-risk areas for green.

It is understood that the health code is divided into three kinds: green, yellow, red. Among them, the green code means "no abnormalities", you can pass normally; yellow code means "home isolation", to isolate 7 days; red code means "medical isolation", to focus on isolation for 14 days. Health code red is to be reported to the community, generally need home isolation or several kinds of isolation. A red health code requires 14 days of intensive isolation, proving that you have had contact with a confirmed case. After intensive isolation, you will be required to do four nucleic acid tests and remove the isolation if there are no problems. You'd better report it quickly because one nucleic acid test doesn't mean you're healthy. And the people you have been in contact with are also in need of home or centralized quarantine. I hope you can take the initiative to report for the sake of the epidemic. When the health code becomes yellow or red, you should immediately contact the staff of the community where I am, to report, and according to the community staff prompted to provide participation in the third round of the whole nucleic acid test negative proof, personal identification, the national trip code track query results and personal commitment and other related materials, the community staff will be in accordance with the situation, and to further assess the research and judgment. "The personnel who are really at risk to maintain the same, the implementation of the corresponding control measures; after the research and judgment, there is really no risk of personnel by the community administrator to change the code operation, adjusted to the green code."
