Nearly 80% of the gene spectrum of Wuhan pneumonia virus is similar to SARS. The first case was found in Thailand

Novel coronavirus was first identified by the joint expert group on China's disease control and control in Wuhan, which was uncovered by the end of December last year Up to now, novel coronavirus infection cases in Wuhan have been reported in 41 cases, 7 cases have been cured and discharged, 6 cases have been treated for severe cases, 1 cases have died, and the rest of the patients have stable condition All the patients are receiving isolation treatment at the designated medical institutions in Wuhan The total number of close contacts was 763, 76 of whom had been removed from medical observation and 687 of whom were still under medical observation On January 12, Shanghai public health clinical center, together with Wuhan Central Hospital, Huazhong University of science and technology, Wuhan City Center for Disease Control and prevention, China Center for Disease Control and prevention, Chinese Academy of Medical Sciences, Sydney University and other research institutions jointly announced the gene sequence of one case of Wuhan unidentified pneumonia infection at viral.org and gene library website gisaid Gisaid initiative, headquartered in Munich, Germany, was founded in May 2008 by a group of authoritative medical scientists around the world It is committed to improving the sharing of influenza data More than 70 top scientists, including seven Nobel laureates, signed the agreement Gisaid provides a database platform with public access China novel coronavirus novel coronavirus gene map was published by China's CDC, Chinese Academy of Sciences and Chinese Academy of Medical Sciences on the website homepage GISAID said it is important for the research and diagnosis of new coronavirus and the research of new intervention strategies The novel coronavirus from Wuhan showed 6 samples from the virus phylogeny tree The coronavirus of Wuhan was expressed in red, while the SARS like coronavirus was expressed in blue Previously, many medical experts in the US asked China to share epidemiological and pathological information, including gene sequencing spectrum, in order to jointly study disease response Novel coronavirus (WHO) subsequently issued a statement in official twitter, which received the gene spectrum data of China's disease control department and named the virus detected as 2019-nCoV (2019 new coronavirus) The novel coronavirus (2019-nCoV) gene sequence enables countries to develop specific diagnostic tools to identify and treat infections quickly, ensuring better treatment outcomes and virus control The World Health Organization (who) reiterated the importance of continuing investigations in China to identify the source of the virus and its animal hosts For China's investigation novel coronavirus and the measures to be taken in Wuhan, the WHO (WHO) said its quality can be guaranteed Yuan Guoyong, Professor of infectious diseases in the Department of Microbiology, Li Ka Shing School of medicine, Hong Kong University, said at a press conference of the Hong Kong health protection center that according to the virus gene map, the gene sequence of its related map was compared with other sequencing on the Internet, and the closest one was the bat SARS coronavirus in Zhoushan, Zhejiang Province The new virus related to Wuhan pneumonia belongs to the type 2B of coronavirus, and its gene sequence is 73% the same as that of SARS virus, and it is "close relatives" of two viruses found in bats Andrew Rambaut, an evolutionary biologist at the University of Edinburgh, analyzed the published gene spectrum and found that the virus was 89% similar to the members of sarbecovirus (a subgenus of coronavirus) associated with severe acute respiratory syndrome (SARS) Kevin J olival, vice chairman of the U.S non-profit organization eco Health Alliance and disease ecologist, also published his preliminary analysis of 410bp based on RdRp on his twitter, indicating that Wuhan coronavirus is indeed clustered with the evolutionary branches of SARS related coronavirus As a whole, the coronavirus involved in Wuhan pneumonia is similar to bat SARS virus, but it is still a new type of SARS like coronavirus Bats are very special animals They are mammals, but they can fly They are the only mammals that can fly Bat's immune system is very strong, carrying many kinds of viruses, but it will not get sick Moreover, many human outbreaks of serious infectious diseases are transmitted by bats Rao Zihe, an academician of the Chinese Academy of Sciences and researcher of the Institute of biophysics of the Chinese Academy of Sciences, was recently interviewed by China Science Daily He said that the natural host of SARS coronavirus and mers coronavirus in nature was bats, although the outbreak of mers coronavirus was caused by camel transmission Rao Zihe said that the previous several coronavirus encounters were all caused by viruses originally hosted in wild animals spreading from animals to humans This reminds us that protecting the living environment of wild animals is probably the best way to keep away from the pathogenic infection of wild animals It is very important to reduce the invasion of bats and other wildlife habitat, and avoid the close contact between these natural hosts and human and livestock, which is very important to prevent the occurrence of infectious diseases The World Health Organization said yesterday, Who said that it has launched the three-level communication mechanism (national, regional and headquarters) within who to continue to communicate closely with China's health sector In view of the current situation, the director general of who, Dr tedros adhanom Ghebreyesus) will further consult with the emergency expert committee, and may hold an emergency committee meeting to assess the epidemic in the near future, but it is still not recommended to impose any travel or trade restrictions on China The who China office also warned on its official microblog that it planned to take precautions and protect itself during the Spring Festival 1) Keep hands clean 2) Cover nose and mouth when coughing or sneezing 3) Cook the eggs thoroughly 4) Avoid close contact with respiratory patients 5) Avoid close contact with wild animals or live animals 6) Don't spit anywhere At the same time, Wuhan health and Health Commission reminded that at present, it is in the season of high incidence of infectious diseases in winter and spring It is necessary to keep indoor air circulation, try to avoid the closed, airless public places and crowded places, and wear masks if necessary If there are fever and respiratory tract infection symptoms, especially if the fever persists, please go to the medical institution in time.
