Why has Chaoyang District in Beijing become a "high-risk area"? See the official response and expert interpretation
[Global Times reporter Ni Hao] According to the query results of the State Council's "Infection Risk Level Inquiry" system as of 18:00 on April 20, Beijing Chaoyang District has been classified as a high-risk epidemic area and has become the only high-risk area in the country. The other districts and counties in Beijing are shown as low-risk areas. Outside Beijing, Nangang District and Daowai District of Harbin, Suifenhe of Heilongjiang and other places are shown as risk areas in the epidemic.
Chaoyang District of Beijing was listed as a “high-risk area for epidemic situation” on the 20th, which attracted much attention on the Internet. On the afternoon of the 20th, Pang Xinghuo, deputy director of the Beijing Center for Disease Control, responded to this widely-regarded topic at a press conference and said that in accordance with the requirements of the National "Notice on Doing a Good Job in the Prevention and Control of New Coronary Pneumonia Epidemic Diseases According to the Law, Localities need to carry out risk grading, classification, prevention and control according to the local new coronary pneumonia epidemic situation. The grading standard for high-risk areas is that there are more than 50 confirmed cases and there is a cluster of epidemic outbreaks within 14 days. According to this standard, on April 14, an imported case diagnosed in Chaoyang District, Beijing, caused a related case of 3 people in its family and became a cluster epidemic. Therefore, the risk level of the outbreak in Chaoyang District is designated as a high-risk area.
According to the epidemic information released by the Beijing Health and Health Commission on the 20th, as of 24:00 on the 19th, there were 419 cases diagnosed in Beijing. 15 out of 16 districts in the city had no newly diagnosed cases for more than 27 consecutive days, and Chaoyang District not only accumulated 75 cases, but also had a cluster epidemic on the 14th, which has reached the high-risk area announced by Pang Xinghuo Judging criteria.
According to the public information query, the Global Times reporter reported that on February 18, the Joint Prevention and Control Mechanism of the State Council issued the “Guiding Opinions on Scientific and Preventive Accurate Policy Division and Grading to Do a Good Job in the Prevention and Control of New Coronary Pneumonia Epidemic Diseases”, requiring all counties (cities, cities, Areas, flags) as a unit, according to the population, the incidence of comprehensive research and judgment, scientifically classify the epidemic risk level, and clarify the prevention and control strategies of low-risk areas, medium-risk areas, and high-risk areas. Among them, it is emphasized that Beijing should continue to do a good job in prevention and control to ensure the safety of the capital. On February 21, the "New Coronavirus Pneumonia Prevention and Control Plan (Fifth Edition)" began to propose, dynamically carry out analysis and judgment, timely adjust the risk level, and after the number of cases remained stable and decreased, and the risk of spread of the disease was effectively controlled, it was divided into regions in time Reduce the emergency response level or terminate the emergency response.
Wang Peiyu, deputy dean of the School of Public Health at the Peking University School of Medicine, told the Global Times reporter on the 20th that the nationwide risk classification in Hubei Province is the most thorough and most concerned. Is Beijing's risk classification standard based on national standards or Beijing standards? Wang Peiyu tends to be a national standard, and another epidemic prevention expert told the Global Times reporter on the 20th that considering Beijing's capital positioning, it may also be a Beijing standard.
The analysis of the above-mentioned epidemic prevention experts said that Chaoyang District has obvious location characteristics. Capital International Airport is under the jurisdiction of Chaoyang District, and Chaoyang District has a large number of embassy districts. Considering that Beijing has a higher risk of imported cases some time ago. Therefore, it is reasonable to raise the risk level of epidemic prevention and control in Chaoyang District.
However, some experts pointed out that the high-risk judgment of Chaoyang District is a bit too strict. Singapore has an area of 724 square kilometers and a population of about 5.64 million, while Chaoyang District has an area of 470 square kilometers and a population of about 3.6 million. Singapore has added 1,426 new cases of new coronary pneumonia on April 20. There are only 75 cases in Chaoyang District.
The above-mentioned epidemic prevention experts believe that the risk of the epidemic situation is dynamically adjusted. With the further implementation of the epidemic prevention and control measures in Chaoyang District, the risk level will be lowered.
The Beijing-Tianjin-Hebei region has just implemented mutual recognition of health codes a few days ago. After the Chaoyang District was upgraded to a high-risk area, the direct impact on people who need to travel to and from Beijing, Tianjin and Hebei has become a hot topic. Some media reported that a neighborhood committee in Shijiazhuang, Hebei Province, said that people returning from Chaoyang District in Beijing must be segregated for 14 days. Tianjin No. 1 Street also indicated that there are corresponding isolation requirements. However, a community in Langfang, Hebei Province, said that there is currently no specific requirements.
Wang Peiyu believes that Beijing upgrades the risk of outbreaks in Chaoyang District, but the prevention and control policies for personnel from high-risk areas are formulated by local governments. Now, there is no unified regulation. It is recommended that those working and living in Beijing who need to travel between Tianjin and Hebei should first understand the local prevention and control policies to avoid unnecessary impact on their own itinerary.
On the 20th, in addition to Chaoyang District becoming the only high-risk area in the country to cause concern, there were some exciting news that day. According to reports, on April 20, a team led by the Qinchuan team of the Chinese Academy of Medical Sciences uploaded a research article on the bioprinter platform bioRxiv. This is the result of the first new coronavirus vaccine animal experiment publicly reported so far. It is reported that the vaccine can induce a specific neutralizing antibody against neocoronavirus in mice, rats and non-human primates. Studies have shown that the vaccine is safe. It is reported that the first publicity of these data will bring hope to people who are looking forward to the new crown vaccine.
