Under what circumstances will the health code become a yellow code? For those who have self-reported information about fever, shortness of breath and respiratory symptoms, those who were cured and discharged within 0/4 days of the confirmed case/kloc-,those who were released from isolation within 0/4 days of the asymptomatic infected person/kloc-,those who have excluded suspected cases, close contacts who have been released from medical observation and those living in high-risk areas, the priorities shall be determined by the autonomous region's epidemic response work headquarters. At the same time, staying with the confirmed cases or asymptomatic infected people for more than 10 minutes in a certain range, and staying in this area for more than 30 hours in recent 14 days means that there is a high risk of infection, and will also be given a yellow code.
With the escalation of epidemic prevention and control, the relevant departments comprehensively use big data and various information resources to accurately trace the trajectory of confirmed cases, and comprehensively sort out the people who overlap with confirmed cases. If there is a trajectory intersection with confirmed cases within 14 days, citizens with "green code" will become "yellow code". "Whether you pass by physically or the communication signal stays in the same grid, it is possible to turn my green health code into a warning yellow code." The relevant person in charge of the provincial big data center said.
