For the key participants in the prevention and control area who have not completed the nucleic acid detection as required, the health code is given yellow code and the flow is appropriately restricted. People who enter and leave these key places after the critical period of confirmed cases and asymptomatic infected people will not be judged as yellow codes. The specific sites and dangerous time periods are determined by the office of COVID-19 Prevention and Control Headquarters of each relevant city according to the on-site epidemiological investigation.
The main people whose health codes suddenly turn yellow are:
/kloc-people from areas with high risk of epidemic situation within 0/4 days, or people who have been to key areas (passing through cities with medium and high risk areas); People in prefecture-level cities with local epidemics and neighboring areas with proliferation risks.
Persons who are abnormal within 14 days in the provincial epidemic database; The discharged patients were cured within 14 days after home observation; Contact with asymptomatic infected people who have received medical isolation for less than 14 days; Overseas personnel who have not completed the quarantine period; Other personnel who need to be included in the management of medium-risk personnel.
