If the health code turns red, first of all, you need to contact the local community immediately and do centralized isolation or home isolation according to local prevention and control regulations.
Under normal circumstances, the health code turns red, which requires centralized isolation or home isolation. During the period of isolation, it is necessary to strictly cooperate with the local health monitoring and management, and accept nucleic acid sampling and testing according to the prescribed frequency. Don't worry too much even if the health code turns red. If you feel unwell, report it in time. When you have completed the specified isolation period, and the nucleic acid test is negative and healthy, your health code will be automatically changed to "green code" after the local assessment meets the conditions for lifting the isolation.
