What does healthy blue code mean?

The healthy sapphire code and the green code are at the same level, both indicating safety. Some places are blue and some places are green. The green code is asymptomatic, healthy and normal at present, and can be used for personnel flow and return to work. Valid for 3 days, you need to punch in your health status within 3 days, otherwise it may be converted into gray code. More than 100 cities in China plan to launch epidemic prevention health codes, which have covered more than 700 million people and accumulated more than 500 million people, making them the most popular epidemic prevention health codes.

Function of health code

Health codes are divided into green codes, yellow codes and red team codes. After comparison and verification, the data of four types of personnel in the provincial epidemic prevention database will be given a green code for those who have not been found, a yellow code for those who have been found in close contact with the tube after comparison and verification, and a red team for those who have been found in confirmed cases, suspected cases, fever cases and asymptomatic infected persons after comparison and verification. In accordance with the requirements of epidemic prevention and control, red team personnel were admitted and isolated on the spot. Passengers with health codes must strictly abide by local travel control measures and cooperate with the management of health code inspectors.
