The change of health code to "yellow code" means that the relevant personnel have a certain risk of COVID-19 infection. In this case, people who have contact with the health code may also turn yellow after the health code turns yellow. Therefore, when the health code becomes Huang's, it must be reported in time to the nearest medical institution or third-party testing institution for nucleic acid testing. At the same time, it is best to do personal protection and reduce contact with others.
Health code yellow code personnel should implement measures such as nucleic acid detection and health monitoring, and do personal protection, minimize the flow, and consciously suspend collective activities such as dinner and participation. Do not enter hotels, shopping malls, supermarkets, stations, airports, cinemas, KTV, bars and other public places, as well as schools, various prisons, nursing homes and welfare homes and other special places. If you feel unwell, you should do personal protection, avoid taking public transportation, immediately go to the nearest fever clinic for nucleic acid screening, and report the epidemiological history on your own initiative.
