For example:
Shantou health code blue represents people with normal body temperature, and red represents people with fever. If the tester selects the wrong temperature result, it cannot be modified or deleted. You can scan the Volkswagen Yuekang code again and submit the temperature registration again to ensure that there is no problem in the latest temperature test.
Note: At present, in most areas, health codes have three most common states, and their meanings are different:
1, green code: currently in a healthy state and can pass the temperature test.
2. 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.
3. 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, which has important practical significance.
