Chaoyang District, Beijing, was listed as a high risk area of the epidemic on the Internet on the 20th. Novel coronavirus pneumonia, 20, novel coronavirus pneumonia, was released on the afternoon of the afternoon of March 5, 2008. Pang Xinghuo, deputy director of the Beijing Municipal Center for Disease Control and prevention, responded to this widely concerned topic at the press conference. According to the states notice on the prevention and control of new crown pneumonia in accordance with the law, all locals need to carry out risk classification and classification prevention and control according to the new crown pneumonia epidemic situation in the locals. The classification criteria for high-risk areas are cumulative diagnosis. There were more than 50 cases, and there were aggregative epidemics within 14 days. According to this standard, on April 14, a case of imported cases from abroad was confirmed in Chaoyang District of Beijing, which resulted in three related cases in their families and became a clustered epidemic. Therefore, Chaoyang District is 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, the total number of confirmed cases in Beijing was 419. 15 out of the 16 districts in the city have no newly confirmed cases in 27 consecutive days, while Chaoyang District not only has a total of 75 cases, but also has a clustered epidemic in 14 days, which has reached the evaluation standard of high-risk areas published by Pang Xinghuo.
Novel coronavirus pneumonia, according to public information, was issued by the Global Times reporter in February 18th. The joint defense joint control mechanism of the State Council issued the guidance on the prevention and control of new crown pneumonia in the area of scientific control and precision measures, and demanded that all counties should be divided into counties, cities, districts and flags, and the risk level of the epidemic should be scientifically classified according to the population and incidence, and the low risk area should be defined. Prevention and control strategies for medium risk area and high risk area. Among them, it is proposed that Beijing should continue to do a good job in prevention and control to ensure the safety of the capital. In February 21st, the novel coronavirus pneumonia prevention and control plan (Fifth Edition) was put forward. The analysis and judgment were carried out dynamically, and the risk level was adjusted timely. After the number of cases was steadily decreased and the risk of epidemic spread was effectively controlled, the emergency response level or the emergency response were reduced in time.
Wang Peiyu, vice president of the school of public health, Peking Universitys medical department, told the global times Tuesday that Hubei Province has the most thorough risk classification and is the most concerned province in the country. Is the risk classification standard of Beijing based on national standard or Beijing standard? Wang Peiyu tends to be the national standard, while another epidemic prevention expert told the global times on the 20th that considering the location of Beijings capital, it may also be the Beijing standard.
According to the analysis of the above epidemic prevention experts, Chaoyang District has obvious location characteristics, the Capital International Airport is under the jurisdiction of Chaoyang District, and Chaoyang District has a large number of embassies, considering the high risk of imported cases in Beijing in the past. Therefore, it is reasonable to improve 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 too strict. In novel coronavirus pneumonia, Singapore has an area of 724 square kilometers with a population of 5 million 640 thousand, while Chaoyang District has an area of 470 square kilometers and a population of 3 million 600 thousand. Singapore has added 1426 new cases of crown pneumonia in April 20th. There are only 75 cases in Chaoyang District.
According to the above epidemic prevention experts, the epidemic risk is dynamically adjusted. With the further implementation of epidemic prevention and control measures in Chaoyang District, the risk level will be lowered.
After the mutual recognition of health codes has just been implemented in Beijing, Tianjin and Hebei, and Chaoyang District has been upgraded to a high-risk epidemic area, it has become a hot topic which will have a direct impact on the people who need to go back and forth in Beijing, Tianjin and Hebei. According to media reports, a residential committee in Shijiazhuang, Hebei Province, said people returning from Chaoyang District of Beijing must be intensively isolated for 14 days. A street in Tianjin also said it had corresponding isolation requirements. However, a community in Langfang, Hebei Province, said there were no specific requirements.
Wang Peiyu believes that Beijing has upgraded the risk of Chaoyang District, but the prevention and control policies for personnel from high-risk areas are formulated by local governments, and there is no unified regulation. It is suggested that when people working and living in Beijing need to travel to and from Tianjin and Hebei, they should first understand the local prevention and control policies to avoid unnecessary impact on their own itinerary.
In addition to Chaoyang District becoming the only high-risk area of the epidemic, there were some encouraging news on the same day. According to reports, on April 20, a team led by the Qinchuan team of the Chinese Academy of Medical Sciences uploaded research articles on biorxiv, a platform for preprinting this paper. This is the first animal experiment result of new coronavirus vaccine publicly reported so far. According to the report, the vaccine can induce new coronavirus specific neutralizing antibodies in mice, rats and non-human primates. Studies have shown that the vaccine is safe. The report said the first disclosure of these data gave hope to people looking forward to the new crown vaccine.
