More than 20,000 local cases of COVID-19 have been reported.
China News Network Beijing on March 17Zhang Yilin: There were 1,226 new confirmed cases and 1,206 asymptomatic cases in 31 Chinese provinces on Tuesday, bringing the total number of confirmed cases to more than 20,000 since March.The surge in local cases, the escalation and mutation of the virus, the loss of key sites…The epidemic has brought many warnings to local prevention and control.Warning 1: “Invisible enemy” is more hidden. Recently, many places in China have seen local clusters of epidemics, mainly omicron variant strains, which spread quickly and have strong concealment.Lei Zhenglong, deputy director of the NHC disease Control and Prevention Bureau and first-level inspector of the NHC, stressed on The 15th that the transmission power of the Omicron variant strain is significantly stronger than that of other Novel coronavirus variants. In the past two months, the proportion of the Omicron BA.2 subbranch has also significantly increased, further enhancing its transmission power.Jilin, Shandong, Zhejiang, Hebei…Many reported outbreaks were caused by the Omicron BA.2 subtype.According to Zhao Qinglong, director of the emergency response office of the Jilin Center for Disease Control and Prevention, omicron BA.2 is about 30 percent more infectious than the previously circulating BA.1, and its replication titer in bronchial tissue is 70 times that of the Delta variant.As the novel Coronavirus continues to “evolve”, the transmission of COVID-19 is becoming more complex and hidden, making prevention and control more difficult. It is therefore necessary to maintain undiminished awareness of prevention and control and not relax all prevention and control requirements.It is worth noting that in this round of epidemic, the proportion of severe cases is decreasing and the number of asymptomatic infected persons is high.Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and Prevention, said on Monday that the omicron strain is relatively weak, which makes a large proportion of infected people have no symptoms or have very mild symptoms, which are hard to detect, adding to the difficulties of epidemic prevention and control.In the face of the new transmission characteristics of the novel Coronavirus variant strain, our response “measures” are constantly updated to ease the strain on medical resources and the pressure of epidemic prevention and control.As the omicron variant strain patients are mainly asymptomatic infected and mild cases, most of them do not need much treatment, and all of them are admitted to designated hospitals, which will occupy a lot of medical resources.The Medical Administration bureau of the National Health Commission of China released guidelines on COVID-19 Diagnosis and Treatment (Trial version 9) on Monday.This version of the revised, the implementation of classified treatment of cases.Mild cases are subject to centralized quarantine management, and the relevant centralized quarantine sites cannot isolate people entering China and close contacts at the same time.Symptomatic treatment and condition monitoring should be done well during isolation management. If the condition worsens, the patient should be transferred to a designated hospital for treatment.The picture shows a postal Courier carrying out nucleic acid sampling.Warning 3: Do not be paralyzed, key places should not leak campus, hospitals, isolation points, express transfer stations……Recently, there have been some key locations among the confirmed cases in many places, indicating the potential risks of this round of epidemic.15, Shanghai held a press conference, the isolation site management negligence caused local infection and led to the spread of a huge impact, a profound lesson.An investigation team has been set up in Shanghai to carry out a special investigation on the quarantine point of huating Hotel.As the “frontier outpost” of epidemic prevention and control, the role of centralized isolation points should not be underestimated, and the closed-loop management of staff at high-risk posts such as isolation points is particularly important.In addition, novel coronavirus positive cases were found in schools, hospitals, express delivery stations and other key locations in some regions, indicating risks and loopholes in epidemic prevention and control.Wang Dengfeng, director of the Ministry of Education’s physical education, Health and art Education department, said on Thursday that students caught the epidemic may have been paralyzed and relaxed, especially when the epidemic has remained stable for a long time.The National Health Commission (NHC) said it would establish a regular risk screening mechanism at ports, centralized quarantine points, designated medical institutions and other high-risk places.Citizens wait for nucleic acid tests in Changchun.Guo Jia photo warning four: Can not lie flat!”Dynamic zero-out” must adhere to the sporadic domestic epidemic, which is characterized by a large number of local clusters with wide coverage and frequent occurrence, making epidemic prevention and control more difficult.Zhang Wenhong, director of the National Center for Infectious Diseases and the department of Infectious Diseases at Huashan Hospital affiliated to Fudan University in Shanghai, said the pace of prevention and control should not be chaotic, and people should not lose confidence in the next stage of prevention and control.If China opens up rapidly now, a large number of people will be infected in a short period of time. Even if the case fatality rate is low, medical resources will run out and social life will be temporarily shocked, causing irreparable harm to the society and families.He said it is important for China to continue its social zero-out strategy to suppress the fifth wave of the omicron epidemic, which is spreading very fast, at a completely controllable level.Lei also said that China’s current general policy of “dynamic clearance” and a series of prevention and control measures are effective in dealing with the omicron mutant epidemic.Vaccination against COVID-19 can effectively reduce the rate of severe illness and fatality.The characteristics of the faster spread and stronger stealth of the omicron variant require earlier, faster, stricter and more solid prevention and control measures.(after)
