Novel coronavirus pneumonia’s "Four Early" Technical Scheme



“Four Early” (early detection, early reporting, early isolation and early treatment) is an important means of infectious disease prevention and control.

In order to effectively promote the implementation of the “four early days” and help the war of annihilation of the novel coronavirus pneumonia epidemic, this technical scheme is formulated in accordance with relevant laws, regulations and plans, in combination with the characteristics and development trend of the novel coronavirus pneumonia epidemic, and on the basis of summing up the experience and lessons of the previous novel coronavirus pneumonia epidemic prevention and control work.


Early detection, early report


Early isolation and treatment

Early detection, early report

–Case Surveillance Report

In order to further improve the ability of early detection of cases, all provinces (autonomous regions and municipalities) should set up a novel coronavirus pneumonia surveillance network, whose member units include various medical institutions and disease prevention and control institutions at all levels.

1. Monitoring objects: fever (body temperature is greater than 37.4 ℃), accompanied by upper respiratory tract symptoms, suspicious contact history or travel history.

2. Monitoring Time: As of December 2020, medical institutions of all levels and types and disease control institutions have carried out daily case monitoring and investigation.

3. Monitoring Location: All outpatient and emergency departments, fever clinics, inpatient wards and other relevant clinics carry out case monitoring.

4. Specimen Collection and Laboratory Testing: Medical institutions collect clinical specimens of cases (see the Specimen Collection and Testing Section of novel coronavirus pneumonia Prevention and Control Plan (Fifth Edition) for details) and send them to the laboratories of local designated disease control institutions or medical institutions or third-party testing institutions for testing.

5. The institution undertaking the testing work shall immediately carry out the testing after receiving the specimen, and complete and feedback the testing results within 24 hours.

6. Environmental specimen monitoring and seroepidemiological investigation: timely carry out according to actual needs.

7. Epidemiological investigation: The CDC shall immediately carry out an epidemiological investigation after receiving the case report and complete it within 24 hours. At the same time, quickly track close contacts to prevent the spread of the epidemic.

8. Case Report: Medical institutions shall immediately carry out direct online reporting after discovering the case. CDC shall immediately investigate and verify the case after receiving the report, and complete the three-level confirmation review within 2 hours. If there is no condition for direct online reporting, fill in the infectious disease report card and send it to the disease control institution within 2 hours, and the disease control institution will carry out direct online reporting.

9. Medical institutions shall, within 24 hours, timely classify cases according to laboratory test results and in combination with the progress of the disease, and revise the cases directly reported on the network according to the clinical severity.

Early detection, early report

-Aggregation epidemic

Aggregation Epidemic Surveillance Report

Within 2 hours after receiving the report of the aggregated epidemic situation, the CDC shall conduct direct network reporting within the management information system of public health emergency reporting. At the same time, it shall report to the local health administrative department, which shall immediately report to the local people’s government, and at the same time report to the higher health administrative department and the health administrative department under the State Council.


Early detection, early report-

Community/Unit, Individual


Community Epidemic Surveillance

Joint prevention and control, group prevention and control, grass-roots communities (villages), units to implement grid management, do a good job in the jurisdiction and unit personnel contact arrangement, health monitoring registration and body temperature monitoring, found suspicious cases in a timely manner to the nearby disease prevention and control institutions or medical institutions.


Unit and individual monitoring

Encourage units and individuals to report to nearby disease prevention and control institutions or medical institutions in a timely manner when they find novel coronavirus pneumonia patients or suspected novel coronavirus pneumonia patients. Novel coronavirus pneumonia patients or suspected novel coronavirus pneumonia patients who refuse to cooperate can be enforced according to the Class B and Class a provisions in the Infectious Disease Prevention Law.



Early isolation and treatment


Isolated Medical Observation and Close Contact Management

All provinces should set up centralized medical isolation observation points. After the relevant cases are found, isolation measures shall be taken immediately to track close contacts, and localized management of on-site medical treatment and epidemic prevention and control of suspicious cases shall be implemented to prevent the spread of the epidemic.

At the same time, do a good job in medical personnel protection measures to prevent hospital infection. County (district) level health administrative departments in conjunction with the relevant departments to organize the implementation of close contact tracking and management, should be in accordance with the close contact management plan (fifth edition) clearly lift the isolation standard.

Medical treatment

Each province has designated designated hospitals and set up a medical treatment expert group to guide the hospitals to do a good job of medical treatment after the occurrence of cases, to push forward the medical treatment threshold, to provide medical services in advance, to strengthen medical treatment for patients with mild diseases, to reduce the transformation from mild diseases to severe diseases, to focus on strengthening the treatment of severe cases, and to reduce the mortality rate.

All medical institutions classify patients according to the Diagnosis and Treatment Plan, and adopt symptomatic and supportive treatment, antiviral, anti-inflammatory, integrated traditional Chinese and Western medicine and other methods to treat them comprehensively. Patients who meet the criteria for release of isolation and discharge are arranged to be released from isolation or discharged from hospital in a timely manner.
