Comprehensive report of The Paper
At 10:00 am on March 24, Shanghai held a press conference on epidemic prevention and control. Wu Jinglei, director of the Municipal Health Commission, Li Rui, deputy head of Minhang District, Fu Chen, director of the Municipal Center for Disease Control and Prevention, and Yu Zhonghua, deputy mayor of Dachang Town, Baoshan District, introduced the latest situation of the epidemic in Shanghai.
Notice at the meeting: From 0 to 24:00 on March 23, 4 new local confirmed cases of new coronary pneumonia and There were 979 asymptomatic infections, of which 4 confirmed cases and 878 asymptomatic infections were found in isolation and control, and the rest were found in the investigation of relevant risk groups. There were 10 new confirmed cases of imported new coronary pneumonia and 3 asymptomatic infections, all of which were found in closed-loop control.
According to the relevant requirements of the Joint Prevention and Control Mechanism of the State Council and the confirmed cases announced today, the Municipal Leading Group Office for the Prevention and Control of the New Coronary Pneumonia Epidemic Prevention and Control has decided to make Xingnan Village, Meilong Town, Minhang District, from now on. The third team, the third team of Xupu Village, Huacao Town, and No. 19, Lane 935, Miaoqiao Road, Kangqiao Town, Pudong New Area are listed as medium-risk areas, and relevant areas have implemented control measures.
The new version of the “Guide” is here. What adjustments have Shanghai Nucleic Acid made?
A reporter asked: The National Health and Medical Commission released the third edition of the new coronavirus nucleic acid detection guidelines the day before yesterday, adjusting some specific requirements. Could you please introduce, what are the main adjustments in the third edition? How did Shanghai do it?
Wu Jinglei, director of the Municipal Health Commission, introduced that compared with the second edition of the “Guide”, the third edition of the “Guide” has three major adjustments:
First, The delineation of nucleic acid detection areas is more refined.
The “full staff” in the second edition of the “Guide” is changed to “area”, and the size of the area is determined by the needs of epidemic prevention and control. Taking the regional screening in this city as an example, we adopted the method of dicing and grid promotion to expand the coverage of screening. During March 16-20, we carried out large-scale nucleic acid screening in key and non-key areas. Screening. On this basis, we further narrowed down and locked key areas according to the distribution of abnormal screening personnel, and on this basis, made more scientific cuts, and continued to carry out accurate screening for high-risk areas. Quickly identify potential close and sub-close connections, manage risk sources in a timely manner, and speed up investigation.
The second is to shorten the time limit for nucleic acid detection to complete the task.
The second edition of the “Guide” requires that “Cities with a population of less than 5 million should complete the nucleic acid testing of all employees within 2 days, and cities with a population of more than 5 million should complete the nucleic acid testing of all employees within 3 days. Task”. The third edition of the “Guide” is aimed at the rapid spread and strong concealment of the Omicron strain, and requires that nucleic acid testing within the designated area be completed within 24 hours. This requirement is in line with the prevention and control requirements currently adhered to by Shanghai, “to be fast and to stay ahead of the virus”.
The third is to optimize the “collection, delivery, inspection, reporting” and other links.
Nucleic acid testing is not only about the mobilization of community personnel, the maintenance of order by volunteers, the sampling and testing of medical staff, etc., but also important information support, matching scheduling of collection and inspection, rapid disposal of positive results, Material security, medical waste disposal, news publicity, comprehensive coordination, etc. The third edition of the “Guide” strengthens these important links based on the experience of nucleic acid screening from all over the country, and requires all localities to set up special classes, in order to more fully realize the rapid scheduling, integration, and full realization of resources in a shorter time. Playing a role provides organizational security.
Wu Jinglei said that in the next step, in accordance with the requirements of the third edition of the state, we will refine the organization and implementation plan, strengthen staffing, improve work flow, and strengthen the coordination and coordination of the whole process of “collection, delivery, inspection, and reporting”. Accurate scheduling, summarizing experience in practice, and continuously improving nucleic acid detection capabilities.
A negative antigen test is not a substitute for a negative nucleic acid certificate
A reporter asked: Can Shanghai public medical institutions provide new coronavirus antigen testing services? When citizens go to the hospital, under which conditions should nucleic acid testing be performed, and under which conditions can antigen testing be performed?
Wu Jinglei, director of the Municipal Health and Health Commission, said that recently, the National Health and Health Commission issued the “New Coronavirus Antigen Detection Application Program (Trial)”. An important feature of antigen detection is that it is fast and simple, which can help Improve the ability of early detection of cases, it is an important supplement to nucleic acid testing. Compared with the two methods, antigen detection is convenient and fast, but the sensitivity is slightly lower; nucleic acid detection is relatively complex, and the detection time is long, but the sensitivity and specificity are relatively high, so it is used as a diagnostic method. Nucleic acid testing is still the basis for the diagnosis of new coronary pneumonia infection, and a negative antigen test cannot replace a negative nucleic acid certificate.
Wu Jinglei said that, based on the characteristics of antigen detection and nucleic acid detection, in order to give full play to the advantages of antigen detection, and to grasp and discover those who are positive for antigen detection faster and more fully, the work of antigen detection is mainly carried out in specific groups. Or organized by collective units, once abnormal test results occur, nucleic acid testing and review will be carried out immediately. At present, antigen testing is mainly used in conjunction with nucleic acid screening. If there is supply in the market in this city, the operation must be carried out in strict accordance with the product instructions. Once the test results are abnormal, they should be reported immediately, and go to the fever clinic for nucleic acid testing according to the standardized procedures.
