The health code is green, but it is black when scanning in the community. What does this mean?

Code black is a health code, and the system is under review.

The health code system is updated in real time according to the comprehensive situation of citizens. If you stay in areas of epidemic concern or come into contact with high-risk personnel, the health code will become red team. During the epidemic period after the health code is launched, the dynamic management of green, yellow and red can be used to judge the state of each citizen during the epidemic prevention and control period, and the code can be displayed in residential quarters, offices, restaurants and other occasions to facilitate the needs of the general public for work, life and travel.

Precautions:

Red team: Delegates need to make diagnosis and treatment in designated hospitals or implement centralized medical observation and isolation measures.

Yellow code: represents enterprises that can enter and leave the community and return to work, but it is not recommended to enter and leave crowded public places and take public transport in the city.

Green code: it means that you can travel freely indoors, but you need to do personal protection and cooperate with temperature detection and other related work. Therefore, it is really necessary to pay attention to the health code, but we should pay more attention to daily protection, wear a mask and wash our hands frequently.
