People with yellow codes will automatically record the arrival time as long as they turn on their mobile phones in low-risk areas. After 14 days of isolation, if they do not become secret contacts or cases, the health code will automatically become a green code.
During the period when the yellow code is issued, it is recommended to do a good job in self-health monitoring, reduce unnecessary going out and contact with others, and avoid going to crowded places. The background automatically checks and converts the applicants to generate green, yellow and red "three codes". Holders of yellow and red codes will automatically convert their health codes into green codes after meeting the requirements.
What does the yellow code mean?
The yellow code of health code may not infect COVID-19, but it is a warning color, as long as it is proved that it is not infected with COVID-19. Therefore, people with health code yellow generally do not need to be isolated, but travel will be restricted to a certain extent. For example, people with yellow health code are not allowed to enter public places such as shopping malls, stations and cinemas.
Health QR code
Health codes are based on real data and can be generated by citizens or people who have returned to work through online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.
The function of health code is to quickly identify whether a person has directly or indirectly contacted infected patients through the color of health code. Then through big data analysis, you can directly lock and find people who may be infected.
