Xinzhou gives "red team" to confirmed patients, people in closed control areas, people who have close contact with others, and people who have lived in middle and high risk areas within 14 days. For those who hold "red team", it is not necessary to implement "red team" for everyone by taking control measures such as no travel, diagnosis and treatment in designated medical institutions or centralized isolation places, and isolation medical observation.
Xinzhou City distributes "yellow codes" to key people, time and space companions and other personnel. For those who hold the "yellow code", take measures to restrict travel, do not go out unless necessary, do not enter public places, do not participate in gathering activities, do not take public transport, accept nucleic acid testing, and cooperate with the community to implement epidemic prevention and control measures. Code managers should cooperate with the community to implement isolation control measures according to regulations. If the quarantine medical observation or health monitoring is completed within the specified time limit, the health status is normal and the nucleic acid test result is negative, it will be automatically adjusted to "green code". Under normal circumstances, if there is no abnormality, the system will automatically decode the health code "red code" 14 days and "yellow code" for 7 days.
