A: According to the principle of territorial management and the requirements of epidemic prevention and control, the district and county headquarters will approve the information of people at risk related to the epidemic and confirm the code list. The Municipal Bureau of Industry and Information Technology implements transcoding according to the assignment code list confirmed by the district and county headquarters. The Municipal Bureau of Industry and Information Technology learned in daily work that there are various reasons why Harbin people are yellow-coded in different places, mainly including the following categories:
1. The party concerned has a history of residence in Harbin or a record of repeated nucleic acid tests, and has recently been included in the list of regional nucleic acid tests in Harbin. However, after the party left Harbin, the local community or unit in Harbin failed to grasp the information that the party left Harbin and did not delete the party from the list. Moreover, Harbin nucleic acid detection and analysis system can not query the nucleic acid detection information of other cities in real time, nor can it automatically delete the parties from the list.
Before the list of people who should be checked but not checked is marked with yellow code, the headquarters of all districts and counties in Harbin will call back to check the people on the list. However, sometimes, due to the inaccurate telephone number, the party concerned did not answer the phone and other reasons, it is impossible to confirm whether the party concerned has left Kazakhstan, so we can only give a yellow code to the person who should have checked in Harbin first.
2. During the follow-up investigation of the epidemic situation in Harbin, it is found that the parties concerned have been to the epidemic-related areas or are in the same space with the confirmed personnel during the investigation time, and they are listed as risks in Harbin, so they are marked with yellow code or red team.
3. Family members or friends of the parties use their Longjiang health code or real-name transportation cards, bank cards, vehicles, etc. For activities and consumption in Harbin area, which are determined to have epidemic risk and marked with yellow code or red team.
4. Persons who are listed as key populations, although in other cities, have not done nucleic acid testing within the specified time range, are marked with yellow codes.
