The rule of "space-time accompanying" is added to the standard of health code assignment, that is, the health code is changed to yellow code or red code according to different exposure risks for those who come to China and return to China from middle-high risk areas and abroad, or those who have crossed the travel track with infected people in COVID-19 in the same time period. According to the epidemic prevention policy, the "yellow code" indicates the need for home isolation. "red team" indicates the need for centralized isolation.
At present, the Municipal Health and Health Commission and the Municipal Bureau of Statistics have opened transcoding application channels: if the health code is abnormal due to personal identity and mobile phone number information errors, the individual will apply to his unit or community and provide negative results of nucleic acid test within 48 hours. After the unit or community audit, report to the district and city epidemic prevention and control headquarters for transcoding.
Confirmed cases, fever patients, close contacts or sub-close contacts, people coming to China or entering from high-risk areas, etc. , transcoding should be carried out according to existing rules and procedures after the conditions for removing isolation are met.
