The four epidemic codes refer to the health code (including nucleic acid detection and vaccination information), communication travel code, self-inspection code of peer secret contact personnel and regional epidemic risk level inquiry code.
What does the health law do?
Through the color of health code, you can quickly identify whether a person has passed through provinces and cities with serious epidemic situation and whether he has directly or indirectly contacted infected people. Then through big data analysis, you can directly lock and find people who may be infected. This has important practical significance in the early stage of epidemic prevention and control!
At present, there are three most common health codes with different meanings:
Green code: At present, it is in a healthy state and can pass the temperature test.
Yellow code: indirect contact with the confirmed personnel before, or symptoms of fever and fatigue. Although the body temperature test is normal at present, it needs to be observed in isolation 14 days.
Red team: Needless to say, for confirmed (or suspected) cases, they will be sent to the hospital for treatment at the first time; For other red team personnel, persuasion or centralized isolation observation 14 days.
In short, health code can collect personal historical data (track, consumption, etc. ) and generate QR codes of different colors. Although this can't directly determine whether you are sick or not, it can provide some data reference for the early prevention and control of the epidemic, and it is still very practical!
