? There are three kinds of health codes: green code can be directly input, red code can be isolated for 14 days, and yellow code can be isolated for less than 7 days. The health coding system has formed a set of standards, which can be quickly introduced according to the needs of different regions and the needs of epidemic prevention and control in various places. Through the health code, many health applications such as one-code medical treatment, one-click first aid, psychological assistance, health certificate, health file and so on have been realized.
Health codes are based on real data, and personal QR codes can be generated by citizens or people returning to work through their own online telegrams and backstage cores. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.
