The color change of health code is actually a reflection of your physical condition, or it will change color in different areas. The details are as follows:
1. If you go to high-risk areas or areas with severe epidemics, your health code may turn red or yellow.
2. If there are confirmed patients or suspected patients in the community, the color of the health code may turn yellow or red after arriving in the community.
3. If there are confirmed patients or suspected patients on public transport, you will also become a contact and may be infected, so your health code will turn yellow and red.
In addition, the health code will change color according to its own health status and travel route, and the code also has clear content. Red team said: confirmed patients, suspected patients, asymptomatic infected people, close contacts with confirmed patients and medical observers. The yellow code indicates that non-confidential colleagues, people with fever, fatigue, cough, diarrhea, conjunctival congestion and other symptoms, fever clinic registration, people from other provinces, observation and sign-in records, health check-ups from other provinces and other key attention groups are within 14 days. Green means that there are no symptoms at present, the health status is basically normal, and people can move and resume their work and labor. The validity period is 3 days, and the health card must be automatically punched in within 3 days, otherwise the health code will become a "Gray code".
Accurately speaking, the health password is to quickly identify your basic state through the above-mentioned state, so as to achieve the preventive effect in advance.
