Newly crowned asymptomatic infected individuals are positive on their own nucleic acid test. An asymptomatic infected person is defined as a person who has tested positive for New Crown virus nucleic acid but has no currently self-perceived or clinically recognizable signs and symptoms or imaging features of New Crown pneumonia. Asymptomatically infected persons are infectious. In accordance with regulations governing the management of asymptomatic infected persons during an outbreak, asymptomatic infected persons should be placed under intensive isolation for medical observation. No specific treatment is generally required during this period, but regular blood tests, imaging tests, and antibody tests are required. If the infected person remains asymptomatically infected throughout the quarantine period, the population will be released from quarantine management, and then undergo 7 days of home health monitoring before being contacted for quarantine. If an infected person develops clinical manifestations or imaging changes of CKP during the period of medical observation, and the diagnostic criteria are met, the corresponding treatment will be carried out in accordance with the typology of the diagnosed cases. In the case of asymptomatic infected persons, they should take the initiative to contact the local CDC and wait for transfer and centralized isolation. In times of outbreak, good personal protection and self-health monitoring is the greatest contribution every citizen can make to outbreak prevention and control.
