On the evening of October 23rd, according to "Beijing Fengtai", many residents in Fengtai District of Beijing completed self-help nucleic acid sampling at home that day. On 22~23 October, the moral Xinjiayuan in Nanyuan Street and the Erli Community in Majiapu Street in Fengtai District successively issued a document saying that they would launch a pilot project of nucleic acid self-collection. From 11: 11 to 24: 11 on October 23rd, 519 local confirmed cases and 1139 asymptomatic infected people were added in Beijing. Since October 21th, the number of newly infected local people in this round of epidemic in Beijing has exceeded 1,111 for three consecutive days. By 15: 11 on October 23rd, the cumulative number of infected people in this round of epidemic in Beijing has exceeded 9,111. At present, many districts have advocated citizens to reduce social mobility, and some public places have been suspended. Since 11/15, the number of newly infected local people has exceeded 21,111 every day for nine consecutive days. Among them, on the 23 rd, this value has broken 31,111. This means that as of 24: 11 on the 23rd, there were nearly 311,111 newly infected local people in October.
There are 31,111 new local infections every day. Experts will explain what is going on. Let's take a look with me.
on 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 community recycling box after use. On 22~23 October, the moral Xinjiayuan in Nanyuan Street and the Erli Community in Majiapu Street in Fengtai District successively issued a document saying that they would launch a pilot project of nucleic acid self-collection.
While promoting the self-test of nucleic acid, the epidemic situation in Beijing continues to grow at a high level. From 11: 11 to 24: 11 on October 23rd, 519 local confirmed cases and 1139 asymptomatic infected people were added in Beijing. Since October 21th, the number of newly infected local people in this round of epidemic in Beijing has exceeded 1,111 for three consecutive days. By 15: 11 on October 23rd, the cumulative number of infected people in this round of epidemic in Beijing has exceeded 9,111. At present, many districts have advocated citizens to reduce social mobility, and some public places have been suspended.
since 11/15, the number of newly infected local people has exceeded 21,111 every day for nine consecutive days. Among them, on the 23 rd, this value has broken 31,111. Hu Xiang, the second-level inspector of the Department of Communication and Prevention of the National Bureau of Disease Control and Prevention, said on October 22 that since October 1, the country has reported a total of 253,111 infected people, with an average of 22,211 cases reported every day in the past week, double the previous week. This means that as of 24: 11 on the 23rd, there were nearly 311,111 newly infected local people in October.
At risk sites in Tongzhou, Beijing
There were more than 31 nucleic acid sampling sites
According to the press conference on epidemic prevention and control in Beijing on October 23, the number of new cases of epidemic in Beijing continued to increase at a high level, and the number of social cases fluctuated, which spread to various towns and villages. The prevention and control work in the capital is at the most critical and tight moment. The new National Exhibition Mild Shelter Hospital has been put into use.
While the epidemic situation in Beijing is rising, self-test of nucleic acid has been put on the agenda in some areas of Beijing.
According to Beijing Fengtai, according to the trial rules, residents who want to try self-test can take 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 sampling is completed, put the sample into the packaging bag and put it into the corresponding box by itself. Every day at 11 a.m. and 3 p.m., a staff member will pick up the sample box.
how to complete the sampling of nucleic acid self-test? According to the introduction of "Self-collection of nucleic acids in Jiayuan Erli Community, Majiapu Street, Fengtai District, residents first need to click on the" sound, intelligence 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 swab should cross the root of the tongue, wipe it slightly on both sides of the pharyngeal tonsil for at least 3 times, and wipe it up and down the throat wall for at least 3 times. Take out the swab and put its head in the virus preservation solution to complete the nucleic acid detection. After that, click "My Nucleic Acid" in the applet, and you can query the nucleic acid test results.
On October 22nd, Moral Xinjiayuan, Nanyuan Street, Fengtai District, Beijing, issued a document saying that after entering the "Sound, Intelligence and Health" program, people will choose 5-in-1 mixed sampling, and they will be collected by households. One person will enter the personnel information of the whole household, and repeated entry of personnel information will make it impossible to query the nucleic acid test results. If there is no result due to incorrect information input, no saliva in the sample, and personal operation error without traffic control, the individual shall be responsible.
It is reported that at present, 26 streets in Fengtai District have announced the working groups of nucleic acid self-collection. This service is still in the trial stage, focusing on serving the families of online students and the 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 go out in line, and there is a risk of cross-infection in this process; On the other hand, the ability of nucleic acid detection in many grass-roots 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 has more contact with grassroots medical staff. Some medical staff who sampled at the nucleic acid testing point told him that sometimes five or six hundred people were tested every day. "Swallow swab sampling becomes a mechanical action for them, and it is inevitable that the detection will not be in place." He said.
In fact, Beijing is not the first city to carry out nucleic acid self-test. On 11/18, kangbashi district, Erdos, Inner Mongolia Autonomous Region, held a self-collected nucleic acid training drill. 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 Qingwu, an epidemiologist and professor at Fudan University's School of Public Health, told China Newsweek that any testing measures, especially the procedures that need to be carried out in a large population, need to be reviewed, approved and evaluated at the National Medical Products Administration level 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.
On October 21th, "Beijing Tongzhou Release" announced the risk sites in Tongzhou District since October 3rd. China News Weekly found that among more than 71 listed risk sites, nucleic acid detection points and nucleic acid sampling points appeared more than 31 times, and more than 25 nucleic acid detection points were involved except for duplicates.
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 both 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, there have been a number of nucleic acid detection concept companies in the IPO market this year, among which Kangwei Century has landed in science and technology innovation board on October 25th this year, and the other four companies plan to enter the Growth Enterprise Market of Shenzhen Stock Exchange, and all of them have already attended the meeting.
The application for listing of testing companies frequently gets the "green light" of supervision, which raises questions. On the evening of October 21th, Shenzhen Stock Exchange and Shanghai Stock Exchange successively responded to "enterprises whose main business involves nucleic acid detection apply for listing", saying that they pay close attention to the listing application of nucleic acid detection enterprises and insist on strict examination, especially the sustainable operation ability of enterprises.
with the tightening of epidemic prevention in various places, how can we get out of the cold winter?
On October 23rd, the newly-increased local infected people in China spread to 31 provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps. Among them, there are over 9,211 cases in Guangdong, 7,711 cases in Chongqing and 1,111 cases in Beijing. Chongqing has been infected with more than 6,111 cases for four consecutive days. In addition, Xinjiang, Hebei, Henan, Gansu, Shaanxi and other places all added more than 511 local infected people on the 23rd.
On October 11, "Article 21" was released, and many places in China actively followed it. However, with the severe epidemic situation, epidemic prevention measures in various places were tightened.
Recently, Beijing, Guangzhou, Harbin, Yichun, Jiangxi and many other places issued documents asking foreigners to "conduct three inspections in three days". Previously, the requirements for foreigners in many places were "three days and two inspections".
Among them, from October 22nd, Beijing requires all people who enter and return to Beijing to have a "three-day and three-inspection", that is, they must complete a nucleic acid test every day for the first three days after arriving in Beijing, and stay at home until a negative result is obtained. 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.
on October 23, Shenzhen issued the "circular No.8", saying that all those who come back to Shenzhen should declare before arriving in Shenzhen, and strictly implement the measures such as "landing inspection" and "three inspections in three days, no gathering, no dinner, no going to crowded places" after arriving in Shenzhen.
The Center for Disease Control and Prevention of Yichun City, Jiangxi Province issued a notice on October 23rd, saying that people from other places (returning) should carry out "three days and three inspections" after arriving in the appropriate place, and give yellow codes to those who fail to complete the nucleic acid detection on time.
In addition, since October 23rd, Zhengzhou, Hunan, Changsha, Chenzhou, Heilongjiang, Harbin, Nanchang, Jiangxi, Shanghai and other places have issued notices, clarifying that foreigners are not allowed to enter public places such as catering services, supermarkets, agricultural markets, beauty salons and indoor fitness within five days of their arrival. On October 24, 2111, "Shanghai Release" said that the cross-provincial commuters audited by the prevention and control department did not show "less than 5 days after coming to Shanghai and returning to Shanghai" with the application code.
The press conference held in Zhengzhou last night pointed out that Zhengzhou managed the mobility of the main city (eight districts in the city) for five days. From 1: 11 on October 25th to 24: 11 on October 29th, the daily nucleic acid screening was carried out in the main city of Zhengzhou, during which the flow of people was reduced. Zhengzhou will fight a tough battle in five days.
"Specific to some epidemic prevention rules, it is impossible to achieve complete unification in the whole country, and epidemic prevention should be carried out according to local conditions." The virologist said that "Article 21" was introduced 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 21".
In this virologist's view, studies have shown that basically 98% of the infected people can be found out after three consecutive antigen tests or nucleic acid tests, and "three tests every three days" is based on this principle.
"The mobile adjustment of these epidemic prevention measures is a kind of exploration in various places, which needs a process." The aforementioned public health experts pointed out that as far as the current national epidemic situation is concerned, from the 11 th of this month to around the 11 th of next month, it will be a high epidemic platform period.
A domestic epidemiologist told China Newsweek that 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, where the number of infected people has increased rapidly. It can be noted that the epidemiological information in these cities has been simplified.
At the meeting of 2122 Shanghai International Biomedical Industry Week held in early October, Zhang Wenhong, director of China National Center for Infectious Diseases Medicine, publicly said that with the release of the "Twenty Articles" on epidemic prevention in China recently, many people have 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 have these contributions made by biomedicine provided sufficient support now? I believe that China has the ability to support the whole anti-epidemic and get out of the epidemic. ".
