Health code is an epidemic prevention and control system. Based on real data, it is declared online by citizens or people who have returned to work, and the personal QR code is generated after background review. Generally speaking, there are three kinds of health codes: green code, yellow code and red code, among which the green code is the safest and can pass normally, and generally does not need isolation.
However, it should be noted that people in high-risk areas may also be observed in isolation when traveling across regions. The health code is located by the mobile phone number, and the green code indicates that the trajectory of residents' mobile phones does not coincide with COVID-19 patients and close contacts; However, it cannot be completely ruled out that residents go out without mobile phones, and the epidemic prevention policies in different regions are different. Even green codes need to be isolated when isolation conditions are met.
The green code is safe. For people in low-risk areas, the green code can pass normally without isolation. If you are forced to quarantine, you can call 12345 for feedback. However, if the mobile phone tracks of COVID-19 patients and close contacts are consistent with the isolation requirements, even if the health code is green at this time, it is necessary to cooperate with isolation to avoid accidents.
