Wuhan completed nearly 9.9 million people testing, and then carry out the city's nucleic acid testing, it is necessary to promote to the whole country?

On June 2, the Xinguan pneumonia outbreak prevention and control headquarters in Hubei Province held the 104th press conference to introduce the results of centralized nucleic acid testing in Wuhan:more than 9.89 million people were tested for nucleic acid, no confirmed cases were foundFrom 0:00 on May 14 to 24:00 on 1 June, Wuhan Concentrated Nucleic Acid Testing 9899828 people, no confirmed cases were detected, 300 asymptomatic infections were detected, the detection rate was 0.303/ million, 1174 close contacts were traced, the nucleic acid test results were negative, and medical isolation was observed on asymptomatic and close contactsat present, Wuhan asymptomatic infection in the whole population accounted for a very low proportion, found no asymptomatic infected infected people infected with other people's infectionThese data represent: Wuhan is safe, Wuhan people are healthyAt the press conference, Li Lanxuan said, "Wuhan's nucleic acid testing has been fully covered, is a rare event in the world, China and even the global epidemic prevention and control has an important guiding role, need to pay special attention to several important data." From 14 May to 1 June of the, 300 asymptomatic infections were screened for nucleic acid testing, with a detection rate of only three in 100,000This shows that Wuhan asymptomatic infected people in the whole population of the proportion of very low, coupled with all the asymptomatic infected people have been found to be isolated observation, that is, usually encounter asymptomatic infected people on the small probabilitySecond, 106 asymptomatic infected people sputum and pharynx swab samples of the virus culture, did not cultivate "live virus";Third, from the distribution point of view, Wuhan City did not screen out asymptomatic infected people in the community accounted for nearly 97%, this proportion has been quite highThis is very important dataOn June 1, the Wuhan CDC collected samples of tap water, domestic sewage, taxis, buses, subway cars and stations, shopping malls, restaurants, parks, etc., and collected samples of some pets, a total of 2,314 samples, all of which were negativeThese data fully demonstrate that Wuhan is safe, Wuhan people are also healthyLi Lanxuan said, "See ingon sit until the city has basically returned to normal, I hope you can believe that the test results and Wuhan's green code, Wuhan and other cities are the same." Since the outbreak of, Wuhan has become the first city in the country to test nucleic acid on a large scaleWuhan Municipal Committee Standing Committee, Executive Vice Mayor Hu Yabo introduced that the cost of centralized nucleic acid testing is borne by the government, through centralized procurement to reduce costs, the total expenditure of about 900 million yuan After more than 10 days of efforts, Wuhan City successfully completed the task of centralized nucleic acid testing, and effectively ensure the health and safety of the people, for the city to resume production, resume school to create a safe and healthy environment On April 8, Wuhan realized the physical sense of unsealing, centralized nucleic acid detection and inspection, "sealing the city" during the great sacrifice of the Wuhan people to achieve psychological desealing keep a close eye on key links, harmonize standards and work processes to ensure that the quality and accuracy of testing the production capacity and quality of nucleic acid testing reagents in China are world-leading, providing strong support for large-scale screening The clinical testing center of the National Health And Health Administration had previously conducted laboratory quality assessments of 889 nucleic acid tests, showing a positive compliance rate of 97% Huada and Da'an genes can be made from 1 to 10 copies of viruses That is, as long as there is a new coronavirus in the sample can be detected, and there will be no false positive problem Zhang Dingyu, deputy director of Hubei Provincial Health Committee and president of Jinyintan Hospital in Wuhan, said, "In order to ensure the quality and accuracy of testing, the test inglises key links, unified standards and work processes, from sample collection, transshipment, preservation, testing, information collection and reporting, biosecurity and other aspects of the clear provisions, such as the provision of sampling The swabs in the throat wipe area, the number of wipes are required, the sample collection tube must have a screw cap, there are washers, freezing, the temperature and time of the sample preservation, such as 4 degrees of preservation days, minus 20 degrees of preservation days In the test, all samplers, laboratory inspectors and other relevant personnel have been unified training, repeatedly strengthen the specification of operating requirements Focus on drawing a group of experienced clinical testing experts to third-party testing institutions for stationing guidance, to ensure that the process norms Mr Feng Zijian, deputy director of the China Center for Disease Control and Prevention and an expert in the liaison group of the State Council's joint prevention and control mechanism, said that Wuhan is now the safest city, although the investigation did not find the case of asymptomatic infected people infected with others, but the city of Wuhan still adopted a "strict prevention" strategy, strictly implement the state's management norms for asymptomatic infected people, strengthen epidemiological investigation, and quarantine observation of close contacts Feng Zijian introduced, asymptomatic infected people to take discovery reports, isolation and disposal of the whole process of closed-loop management, the State Council joint prevention and control mechanism liaison group guide Wuhan City mainly strengthened the following four aspects of management: , strict medical isolation observation Medical isolation observation of asymptomatic infected persons, registration and reporting through information systems, and dynamic management After 14 days of medical observation, two consecutive, 24-hour interval nucleic acid test negative, can be de-isolated Second, the formation of a team of experts to standardize treatment To guide Wuhan To form a team of clinical experts, psychologists experts, to carry out the diagnosis and treatment of asymptomatic infected people, to achieve "one person, one program", preventive intervention of Chinese medicine and anti-viral treatment of Western medicine, 24-hour online psychological counseling Third, strict inspection of active monitoring This centralized nucleic acid test detected asymptomatic infected persons, none of the cases transferred to confirmed cases In addition to IgG single yang, all other in the municipal fixed-point hospital blood routine, lung CT examination Fourth, follow-up follow-up closed-loop management For asymptomatic infected persons in the 2nd and 4th weeks after the lifting of centralized medical observation, to a designated hospital or community health service center follow-up, follow-up visits, timely understanding of their health status, do a good job of follow-up and management after Wuhan, Peony River to carry out the city's nucleic acid testing .. Recently, the new crown pneumonia outbreak in Peony River City, Heilongjiang Province, there have been repeated cases, as of June 2, 24 hours, Heilongjiang has 15 cases of asymptomatic infection, there are still 359 people under medical observation It is reported that on June 1st, the official website of the Peony River Municipal Government released the "City Health And Health Commission to expand the city's nucleic acid testing" information shows that, according to the needs of epidemic prevention and control, in order to complete the timely, efficient and high-quality nuclear acid testing tasks in our city, the city health and health committee further expanded the city's nucleic acid testing sample sampling team, by 11 tertiary medical institutions and 12 secondary medical institutions a total of 1196 people picture: of the Peony River Municipal Government website
in Heilongjiang at the same time, on May 30, the three-level medical institutions selected the personnel with practical experience of sampling the unit as training instructors, through video courseware, theoretical teaching, practical training and one-by-one assessment and other ways to complete the sampler training assessment tasks At the same time, the Municipal Health and Wellness Commission from Kang'an Hospital to draw 10 specimen sampling experts in the 4th floor of Kang'an Hospital conference room for the city's secondary medical institutions sampling team on-site training and assessment, at the meeting on the nucleic acid testing sampling method, packaging transport, preservation and specimen sampling process, specimen registration and handover procedures for detailed explanation and answer questions, in order to carry out the city's nucleic acid testing work to do a good job of adequate preparation June 2 Health Times reporter on the Peony River began the national nucleic acid testing, called the Peony River City CDC, the staff responded that,""a few days ago there were 11 cases of asymptomatic infected people, so the Peony River Municipal Government, the municipal committee decided to screening for the national nucleic acid test." The nationwide screening, which is now conducted on a community-based basis, began testing for free nucleic acids on June 1 "
Wuhan's centralized nucleic acid detection and screening work has begun to show results, is it necessary for the whole country to test? now, the new crown of pneumonia has spread around the world Although China's outbreak has been effectively controlled, but the outbreak abroad has not been fully controlled, foreign imported cases may not wish to The implementation of nationwide nucleic acid testing, carpet screening, timely detection of more potential sources of infection and asymptomatic infection patients, effectively reduce the risk of large-scale population outbreaks in China So is it really necessary to conduct a national test of the whole staff? Experts don't think carpet-type mass screening is needed Wu Zunyou, an epidemiologist at the China Center for Disease Control and Prevention, said on CCTV News 1 and 1 that large-scale screening of nucleic acid tests is not necessary, mainly in key areas, key groups of people In communities where there are no cases, there is no need for everyone to do screening, mainly for priority positions, priority groups, people in key communities to do large-scale screening Similarly, Zhong Nanshan academician on 'Is there no need for universal nucleic acid testing?' 'The answer is also unnecessary He believes that asymptomatic infection scant number of patients, it is difficult to produce a wide range of infections, and is not a threat It is not worth it to find a few asymptomatic infections, which are enough to be tested for the whole people, with enormous financial, material and human resources If the source of infection or the absence of symptoms of infection, increase the detection of close contacts with the patient, the external personnel also take quarantine measures to carry out timely detection Zhang Wenhong believes that nucleic acid testing is only a result, the results only show that at this stage no disease, not after the test can be 'once and for all' And nucleic acid testing is not a single can detect whether a person is infected with the virus, there is the possibility of false negative, which requires re-picking In addition, the detection capacity is limited, the number of people can be tested a day also has a cap, if the real national test, the time is not a few days or weeks or months can be completed, but also the need to retest the possibility Then it is worth while conducting a national nucleic acid test in areas with high incidence rates Nucleic acid testing range can find more potential sources of infection, asymptomatic infection patients, positive infection patients, but should also be clearly aware that the spread of the virus is not static, and nucleic acid testing is static, can only be checked for a certain time, and other parts of the country incidence is not high, the probability of infection sources and asymptomatic infection patients is very low, and then considering the need to spend huge financial, material, human resources to check low probability events, is undoubtedly not worth Combined with the actual situation, it is necessary to be able to pay attention to the identified infected patients and asymptomatic infection patients, timely check the relevant close contacts, while the external personnel to do a good job of isolation measures and other related troubleshooting work, reduce the risk of a second large-scale outbreak of infection patients This approach may be more effective Source: CCTV News, Health Times, Heilongjiang Health Committee, Beijing Daily, Yan News, Hubei News and Sina.com source:
