People’s governments of all provinces, autonomous regions and municipalities directly under the central government, ministries and commissions under the State Council, and organizations directly under the State Council:
“Novel coronavirus asymptomatic infection management guidelines” has been in the Central Committee to respond to the new coronavirus infection pneumonia leading group, and is now being issued to you. Please conscientiously implement it.

Mechanism of joint prevention and control of pneumonia

Management of asymptomatic patients with new coronavirus infection
Article 1 These Regulations are formulated in accordance with the law of the people’s Republic of China on the prevention and control of infectious diseases and the frontier health and Quarantine Law of the people’s Republic of China for the purpose of strengthening the discovery, reporting and management of asymptomatic new coronavirus infected persons.
Article 2 asymptomatic infection of new coronavirus (hereinafter referred to as asymptomatic infection) refers to those who have no relevant clinical manifestations, such as fever, cough, sore throat and other self perceived or clinically recognizable symptoms and signs, but whose pathogenic test of new coronavirus on respiratory tract and other specimens is positive. There are two situations for asymptomatic infection: first, after 14 days of isolation medical observation, there are no self perceived or clinically recognizable symptoms and signs; second, the state of “asymptomatic infection” in the incubation period.
Article 3 asymptomatic infections are infectious, and there is a risk of transmission.
Fourth article Novel coronavirus pneumonia surveillance novel coronavirus pneumonia novel coronavirus pneumonia is also a major factor in the surveillance of asymptomatic infectious diseases. First, the active contacts of close contacts of new crown pneumonia cases during medical observation are detected. Two, active detection in the investigation of clustering epidemic; three, detection of the main exposure of the exposed population in the tracing process of the new crown pneumonia cases; four, the history of some people who live in the area with new and severe cases of new crown pneumonia. The fifth is the related personnel found in the epidemiological investigation and opportunistic screening.
Article 5 standardize the report of asymptomatic infection. If any asymptomatic infection is found in any medical and health institution at any level, the network direct report shall be made within 2 hours. After receiving the report of asymptomatic infection, the county-level disease control institution shall complete the case investigation within 24 hours, register the close contacts in time, and report the case investigation form or investigation report through the infectious disease report information management system in time. After the asymptomatic infected person is relieved of the centralized medical observation, the medical and health institutions shall fill in the date of dissolution of the medical observation in the infectious disease report information management system in time.
Article 6 strengthen information disclosure. The administrative department of health under the State Council shall publish the reports, outcomes and management of asymptomatic patients every day. Each province (District, city) publishes the situation of its own administrative region, and makes statistical reports on local communication and overseas input respectively.
Article 7 strengthen the management of asymptomatic infection. Patients with asymptomatic infection should be concentrated on medical observation for 14 days. Novel coronavirus pneumonia related clinical symptoms and signs were converted to confirmed cases during the period. If the centralized medical observation is over 14 days and the nucleic acid test of two consecutive samples is negative (the sampling time is at least 24 hours), the centralized medical observation can be cancelled. If the nucleic acid test is still positive and there is no clinical symptom, the centralized medical observation shall be continued.
Article 8 in case of clinical manifestations of asymptomatic patients during the period of centralized medical observation, they shall be immediately transferred to designated medical institutions for standardized treatment, and corrected in time after diagnosis.
Article 9 close contacts of asymptomatic infected persons shall be subject to concentrated medical observation for 14 days.
Article 10 an expert group shall be organized to patrol asymptomatic infected persons under centralized medical observation and discover possible confirmed cases in time.
Article 11 the asymptomatic patients who have been relieved from centralized medical observation shall continue to have 14 days of medical observation and follow-up. In the second and fourth weeks after the release of the centralized medical observation, follow-up visit should be made to the designated hospital to find out the health status in time.
Article 12 targeted screening efforts should be strengthened to expand the scope of detection to those who have close contact with the found cases and asymptomatic infected persons. Strengthen the monitoring of key areas, key groups and key places. Once asymptomatic infections are found, they should be isolated for medical observation.
Article 13 asymptomatic infectors are characterized by concealment of transmission, subjectivity of symptoms and limitations of discovery. The State supports scientific research on the infectivity, transmission and epidemiology of asymptomatic infectors.
The fourteenth is to strengthen information communication, exchange and cooperation with the WHO and other relevant countries and international organizations, and adjust diagnosis and treatment plans and prevention and control plans in due time.
Article 15 all localities should strengthen the publicity of new coronavirus knowledge, guide the public in scientific protection, carry out extensive training, and improve the prevention and control ability and level of grass-roots medical and health personnel and community workers.
