What does the new asymptomatic infected person mean? What should COVID-19 asymptomatic infected person do

Asymptomatic COVID-19 infected persons (hereinafter referred to as asymptomatic infected persons) refer to those who have no relevant clinical symptoms, such as fever, cough, sore throat and other symptoms and signs that can be perceived or recognized clinically, but whose respiratory tract and other specimens are positive for COVID-19 etiology. Asymptomatic carriers can be divided into two situations: one is that the carrier has tested positive for nucleic acid, and after a 14 day incubation period, there are no symptoms or signs that can be self perceived or clinically recognized, and they remain in an asymptomatic infection state; The second is that the infected person tested positive for nucleic acid and had no symptoms or signs that could be self perceived or clinically recognized at the time of sampling, but subsequently showed some clinical manifestations, that is, an "asymptomatic infection" state in the latent period. Medical and health institutions at all levels and types should report asymptomatic infections directly online within 2 hours. County (district) level disease control institutions shall complete case investigations within 24 hours after receiving reports of asymptomatic infections, register close contacts in a timely manner, and report case investigation forms or investigation reports through the infectious disease reporting management information system. Asymptomatic infected individuals should be quarantined for 14 days. In principle, those who have been quarantined for at least 14 days and have tested negative for nucleic acid in two consecutive samples (with a sampling interval of at least 24 hours) can be released from quarantine; If the nucleic acid test is still positive, continue to isolate and undergo medical observation. If clinical manifestations occur during the quarantine medical observation period, they should be promptly classified as confirmed cases and receive standardized treatment. Close contacts of asymptomatic infected individuals should also undergo 14 days of centralized isolation and medical observation.
