1. If someone in your community is infected, your health code may turn yellow or red.
2. If you have ever been to a high-risk area, the health code will automatically turn yellow or red.
3. If you take public transportation and someone in the same car is suspected or diagnosed with infection, then as a close contact, your health code will also turn yellow or red.
Health codes are divided into three colors: green code, yellow code and red code.
Red team scope: confirmed patients, suspected patients, asymptomatic infected persons, close contacts with confirmed patients and medical observers.
Yellow code range: non-confidential colleagues of the national diagnosed personnel, those who have fever, fatigue, cough, diarrhea, conjunctival congestion and other discomfort symptoms such as registration, observation and bayonet records of fever clinics, people from other provinces, and key personnel who punch in less than 14 days outside the province.
Green code range: it means that there are no symptoms at present, the health is basically normal, people can move and return to work; The validity period is 3 days, and you must punch in your health card within 3 days, otherwise the health code will be changed to "Gray code".
Through the status of the above three health codes, everyone can quickly identify the basic status of the individual. Of course, the current Alipay health code may be different from Tencent health code, because the data collected by the two are different. It may be the green code on Alipay, but it will become the yellow code on Tencent.
Although this health code won't judge what disease you have or when you got it, it can distinguish whether you have had direct or indirect contact with confirmed patients or suspected patients in novel coronavirus through big data, so as to provide traceability for the prevention and control of novel coronavirus epidemic, and then quickly find possible infected people and take timely measures to prevent the virus from expanding further.
