Why do big events go through red and green?

Convenient management. Liao Shitong's health code has three colors: green code, yellow code and red code, which respectively represent three different health states and are convenient for management. Green code personnel can do a good job of self-prevention and control and accept body temperature examination, and no unit may restrict their free activities without justifiable reasons. The reason why the green code changed to yellow code was that there were few records of contact with confirmed cases or suspected cases in the past 14 days. It is necessary to actively report to communities and units through food hygiene regulations. After continuously reporting 14 days of health information every day, it can be changed to green code or consulting community, and it can be changed to green code of negative proof of nucleic acid test. Management departments at all levels should strictly track and manage the red code personnel, take all necessary measures such as isolation treatment and detection, and implement dynamic management of the three-color health code. Red team's isolation detection is over, and the isolation with yellow code is over. When the condition is met, it will become a green code. Shengshi Tong APP is an application carrier that integrates many functions such as e-passport, nucleic acid detection, medical treatment and drug purchase, and subsidy application.
