After receiving the epidemic report, how to carry out epidemiological investigation and close contact judgment management;

How to carry out epidemiological investigation;

1, complete network direct reporting and transshipment in time.

After receiving the positive report of nucleic acid test, all kinds of medical institutions at all levels should complete the direct network report within 2 hours, and transfer the infected person to the designated hospital within 2 hours. The CDC should investigate and verify the report immediately after receiving it, and complete the audit within 2 hours. Any place shall not increase the consultation, evaluation and other procedures without authorization.

2, the first time to carry out epidemiological investigation.

After receiving the direct network report, the disease control institutions in the jurisdiction should immediately start epidemiological investigation, complete the investigation of basic information, onset and treatment, risk factors and exposure history, laboratory testing and other information of cases and asymptomatic infected persons within 24 hours, fill in the case questionnaire, and accurately determine the contact personnel according to the contact mode, contact frequency and contact duration of infected persons with others.

3. Broaden the traceability of flow regulation.

The survey was supplemented by face-to-face epidemiological survey, visiting attending doctors, consulting cases, supplementary telephone survey, big data tracking, Alipay and WeChat transaction records, and consulting videos.

During the investigation, people, things and environment were checked together, and the epidemiological history of the patient 14 days before the onset was inquired in detail, so as to accurately grasp the information such as contact time, mode, frequency, location, protection situation at that time, comprehensively analyze and preliminarily infer the possible sources of infection, and constantly verify the preliminary inference through sampling and testing people, environment and suspicious objects.

Search for related cases quickly, so as to find related cases or cluster epidemic symptoms as soon as possible and take timely prevention and control measures.

How to judge the secret connection:

1. According to the novel coronavirus Prevention and Control Plan (Seventh Edition), the medical and health institutions reporting cases and the disease control institutions in the counties (districts) where asymptomatic infected people are located will scientifically and accurately judge close contacts and close contacts according to the epidemiological investigation results.

2. Close contacts: First, clear the time point, starting from 2 days before the symptoms of suspected cases and confirmed cases, or starting from 2 days before the sampling of asymptomatic infected people; Second, close contact with suspected cases, confirmed cases or asymptomatic infected persons; Third, there is no effective protection. Close contacts should complete the epidemiological investigation of the case within 24 hours.

3. Close contacts: First, pay attention to the time period, starting from the first contact between close contacts and cases or asymptomatic infected people, until close contacts are isolated and managed; The second is the close contact of close contacts, such as living and working in the same closed environment, dining and entertainment; Third, there is no effective protection.

4. Key observation objects: Although it does not conform to the principle of close contact, according to the actual situation of epidemic prevention and control, key medical observers are needed to prevent the spread of the epidemic as much as possible. It can be controlled according to the control mode of close contacts.

5. General contacts: people who have been in contact with suspected cases, confirmed cases and asymptomatic infected persons on the same means of transportation, such as airplanes, trains and ships, as well as in the process of life, study, work and diagnosis and treatment, but do not meet the principle of judging close contacts.

Close contact personnel control measures:

Close contacts, close contacts, key observation objects and other suspicious persons screened out should be transported to the centralized isolation point within 12 hours, and nucleic acid detection samples should be collected in time to complete the first nucleic acid detection within 24 hours.

"14+3+ 1" (centralized isolation 14 days, during which nucleic acid was detected 3 times and antibody was detected 1 time) and "7+ 1" (after 7 days of home observation or centralized isolation, 65438+ expired).

According to the standard of 1 infected person 100 isolation rooms, make preparations, coordinate the centralized isolation rooms in the area, meet the needs of large-scale personnel isolation, and fully realize "one person for each isolation".
