Function of health code
Health codes are divided into green codes, yellow codes and red team codes. After comparison and verification, the data of four types of personnel in the provincial epidemic prevention database will be given a green code for those who have not been found, a yellow code for those who have been found in close contact with the tube after comparison and verification, and a red team for those who have been found in confirmed cases, suspected cases, fever cases and asymptomatic infected persons after comparison and verification. In accordance with the requirements of epidemic prevention and control, red team personnel were admitted and isolated on the spot. Passengers with health codes must strictly abide by local travel control measures and cooperate with the management of health code inspectors.
