There are 30,000 new local infections every day. Experts explain what this is all about. Come and have a look with me.
165438+1On the evening of October 23rd, according to "Beijing Fengtai", many residents in Fengtai District of Beijing completed self-service nucleic acid sampling at home that day. According to the operation guide, 3-5 people in a family use one tube and put it into the recycling box in the community after use. 165438+1On October 22-23, Moral New Home in Nanyuan Street and Kerry Community in Majiapu Street in Fengtai District successively issued a document saying that they would carry out a pilot project of nucleic acid self-collection.
While promoting nucleic acid self-test, the epidemic situation in Beijing continued to grow at a high level. 165438+1From 0: 00 to 24: 00 on October 23rd, there were 509 newly confirmed local cases in Beijing, with asymptomatic infections 1 139 people. From165438+1October 2 1, the number of newly infected local people in Beijing has exceeded 1000 for three consecutive days. By165438+1October 23 15, the cumulative number of infected people in this round of epidemic in Beijing has exceeded 9,000. At present, many districts advocate citizens to reduce social mobility, and some public places have been suspended.
Since165438+1October 15, the number of new infections in the local area has exceeded 20,000 for 9 consecutive days. Among them, this value has broken 30,000 on the 23rd. Hu Xiang 165438+ 1 22 October, the second-level inspector of the Department of Communication Prevention of the National Bureau for Disease Control and Prevention said that since122 October165438+1,a total of 253,000 cases of infected people have been reported nationwide, with an average of one day in the past week. This means that as of 24: 00 on the 23rd, 165438+ 10 had nearly 300,000 newly infected local people.
Tongzhou, Beijing involves risk points.
Nucleic acid sampling points appeared more than 30 times.
According to165438+the news of the press conference on epidemic prevention and control in Beijing on June 23rd, the number of new epidemic cases in Beijing continued to increase at a high level, and the number of social cases fluctuated, affecting a wide range of towns and villages. The prevention and control work in the capital is at the most critical and tense moment. The new National Convention and Exhibition Center Hospital has been put into use.
While the epidemic situation in Beijing is rising, nucleic acid self-test has been put on the agenda in some parts of Beijing.
According to Beijing Fengtai, according to the trial rules, residents who want to try self-test can take out a "self-test material" from the "nucleic acid reagent" box, including a tube of pink reagent and cotton swabs equal to the number of their families, and make a good registration. After the sampling is completed, put the sample into the packaging bag and put it into the corresponding box by itself. Every morning 1 1, at 3 pm, there will be staff to pick up the sample box.
How to complete the sampling of nucleic acid self-test? According to the introduction of "Self-help Collection of Nucleic Acid in Jiayuan Erli Community, Majiapu Street, Fengtai District", residents first need to click on the "Sound, Wisdom and Health" applet, scan the test tube at the test tube code, fill in the detailed address information and upload the data. When collecting nucleic acid, the cotton swab should pass through the root of the tongue, and be lightly wiped on both sides of the pharyngeal tonsil for at least 3 times, and wiped up and down the pharyngeal wall for at least 3 times. Take out the cotton swab and put its head in virus preservation solution to complete nucleic acid detection. Then click "My Nucleic Acid" in the applet, and you can query the nucleic acid test results.
165438+1On October 22nd, Moral New Home in Nanyuan Street, Fengtai District, Beijing issued a document saying that after entering the "sound, intelligence and health" program, people will choose 6-choice 5+5438+0 mixed sampling and collect them by households. If a person enters the information of the whole household, he will not be able to query the nucleic acid test results. If there is no result due to personal operation errors such as incorrect information input, no saliva in the sample and no traffic control, the individual shall be responsible.
According to reports, at present, 26 streets in Fengtai District have published working groups for nucleic acid self-collection. This service is still in the trial stage, focusing on online families and families of seriously ill or seriously ill elderly people.
"The nucleic acid self-test is equivalent to the' copy' of antigen detection, which is a new attempt, and the specific efficiency remains to be seen." A public health expert said that on the one hand, nucleic acid testing requires residents to queue up to go out, and there is a risk of cross-infection in this process; On the other hand, the ability of nucleic acid detection in many grassroots cities can't keep up, which can be alleviated in this way.
"Beijing started nucleic acid self-test, mainly based on the concept of reducing aggregation." According to the analysis of the aforementioned public health experts, he usually contacts more primary medical staff. Some medical staff who sampled at the nucleic acid testing point told him that sometimes five or six hundred people were tested a day. "Swallow swab sampling has become a mechanical action for them, and it is inevitable that the detection is not in place." He said.
In fact, Beijing is not the first city to carry out nucleic acid self-test. On June165438+1October 18, a self-collected nucleic acid training exercise was held in kangbashi, Inner Mongolia Autonomous Region. The difference is that residents need to go out to the nucleic acid sampling point and conduct self-test under the guidance of nucleic acid testers.
Jiang, a professor at Fudan University School of Public Health and an epidemiologist, said in an interview with China Newsweek that any testing measures, especially procedures that need to be carried out in a large population, need to be reviewed, approved and evaluated at the level of the State Administration of Medical Products to balance the testing quality and technical feasibility. Under the premise of simplifying epidemic prevention measures and relieving the pressure of medical resources, ensuring the accuracy of test results is the basic requirement.
165438+1The Beijing Tongzhou Release published the risk sites in Tongzhou District since165438+13. China News Weekly found that among more than 70 listed risk sites, nucleic acid detection points and nucleic acid sampling points appeared more than 30 times, and more than 25 nucleic acid detection points were involved except duplication.
A virologist said that the gradual adoption of nucleic acid self-collection and antigen detection is a beneficial attempt to make epidemic prevention more scientific, accurate and sustainable. Autologous collection is suitable for nucleic acid detection and antigen detection. Comparatively speaking, the advantages of antigen detection are more obvious. The virologist said that although China antigen detection reagent has played a great role in global epidemic prevention, it has not been fully applied in China at present, and the application of antigen detection should be gradually strengthened in the future.
It is worth noting that, according to media reports, a number of companies with the concept of nucleic acid detection have attended the IPO market this year. Among them, Conway Century landed on the Science and Technology Innovation Board of Shanghai Stock Exchange on June 25th 10, and the other four companies planned to enter the Growth Enterprise Market of Shenzhen Stock Exchange, all of which had already passed the meeting.
Testing companies' listing applications frequently get the "green light" of supervision, which raises questions. On the evening of165438+1October 2 1, Shenzhen Stock Exchange and Shanghai Stock Exchange successively responded to the question of "enterprises whose main business involves nucleic acid detection apply for listing", saying that they pay close attention to the listing applications of nucleic acid detection enterprises and insist on strict examination, especially their ability to continue to operate.
Epidemic prevention has been tightened everywhere. How to get out of the cold winter?
165438+1On October 23rd, the newly-added local infected people spread to 3 1 province (autonomous region, municipality) and Xinjiang Production and Construction Corps. Among them, there were 9200 cases in Guangdong, 7700 cases in Chongqing, 0 cases in Beijing 1 100, and more than 6000 cases were infected in Chongqing for four consecutive days. In addition, Xinjiang, Hebei, Henan, Gansu, Shaanxi and other places all added more than 500 local infected people on the 23rd.
165438+ 10/1,"Article 20" was released, and then many places in the country actively followed up, but with the severity of the epidemic, epidemic prevention measures in various places were tightened.
Recently, Beijing, Guangzhou, Harbin, Yichun, Jiangxi and other places have issued documents requiring foreigners to "conduct three inspections in three days". Previously, the requirement for foreigners in many places was "three days and two inspections".
Among them, from165438+1October 22, Beijing requires all those who go to Beijing and return to Beijing to have a "three-day three-check", that is, they must complete a nucleic acid test every day for the first three days after entering Beijing, and don't go out at home until the negative results come out. If the third test is not completed within three days after arriving in Beijing, Beijing Health Bao will pop up a window to remind you.
165438+1On October 23rd, Shenzhen issued "Circular No.8", stating that all personnel returning to Shenzhen should declare before arriving in Shenzhen, and after arriving in Shenzhen, measures such as "landing inspection", "three inspections in three days, no meetings, no dinners and no crowded places" should be strictly implemented.
Jiangxi Yichun CDC165438+1October 23rd issued a notice saying that "three days and three inspections" will be implemented after the arrival of foreigners (returnees), and those who fail to complete the nucleic acid detection on time will be given a yellow code.
In addition, since1October 23, 165438+, Zhengzhou, Henan, Changsha, Chenzhou, Harbin, Jiangxi, Nanchang, Shanghai and other places have issued notices, clarifying that foreigners are not allowed to enter public places such as catering services, supermarkets, farmers' markets, beauty salons, indoor fitness and so on within five days of their entry. 165438+1On October 24th, the "Shanghai Release" said that the cross-provincial commuters audited by the prevention and control department did not show that "the stay time in Shanghai is less than 5 days".
The press conference held in Zhengzhou last night pointed out that Zhengzhou managed the liquidity of the main city (eight districts in the city) for five days. 1from 0: 00 on October 25th to1October 29th 165438+24: 00, the daily nucleic acid screening will be conducted in the main city of Zhengzhou, during which the number of people will be reduced. Zhengzhou will fight a tough battle in five days.
"Specific to certain epidemic prevention rules, it is impossible for the whole country to be completely unified, and epidemic prevention should be tailored to local conditions." Virologists said that the introduction of "Article 20" is to achieve accurate epidemic prevention and normal epidemic prevention, but the epidemic situation in the country is ever-changing, and it is unrealistic to want to cover everything through "Article 20".
According to virologists, studies have shown that 98% of infected people can be detected by three consecutive antigen tests or nucleic acid tests, and "three tests in three days" is based on this principle.
"The mobile adjustment of these epidemic prevention measures is an exploration in various places and requires a process." The aforementioned public health experts pointed out that from the current national epidemic situation, this month 10 to next month 10 will be a high platform period.
An epidemiologist in China told China Newsweek that in fact, all localities have been optimizing epidemic prevention measures, and some better measures should be shared with other cities as soon as possible, such as the epidemic situation in Guangzhou and Beijing, and the number of infected people has increased rapidly. It can be noted that the epidemiological information of these cities has been simplified.
At the meeting of 2022 Shanghai International Biomedical Industry Week held at the beginning of 165438+ 10, Zhang Wenhong, director of China National Center for Infectious Diseases Medicine, publicly stated that with the recent release of "Twenty Articles" on epidemic prevention in China, many people had more expectations for China to get out of the epidemic in the future. "We know very well in our hearts that it must be science and technology that will eventually get out of the epidemic, but now these contributions made by biomedicine provide enough support? I believe that China has the ability to support the entire anti-epidemic and get out of the epidemic. " .
