Who press conference records that there is no proven therapy to assess the impact of "closure"

On January 22nd, novel coronavirus infection in Wuhan was assessed by WHO at headquarters in Geneva to assess the potential impact of the new coronavirus infection on global public health At about 9 p.m., the World Health Organization held a press conference to make the results of the discussion public Novel coronavirus infection has been identified as "public health emergency of international concern" since the WHO announced today that it would convene an emergency committee meeting The novel coronavirus infection is still progressing, and the situation is very complex, Dr Tedros Adhanom Ghebreyesus, director general of WHO, said at the beginning of the press conference Despite extensive discussions, the Committee has different views on this issue and cannot yet define it as a global public health crisis Tomorrow, the committee will continue its discussion "The global international public health emergency is a very serious issue," Dr ghebreyesus said "We can only make announcements when we have sufficient evidence Our team members are working with local experts in China to investigate and get more information about the outbreak " Shortly before the World Health Organization held a press conference, Wuhan announced that "since 10:00 on January 23, 2020, the city's urban public transport, subway, ferry and long-distance passenger transport have been suspended; without special reasons, citizens should not leave Wuhan, and the airport and railway station access to Wuhan has been temporarily closed" For a while, "Wuhan Fengcheng" was swiping the screen on social media, and journalists from BBC and other media also asked the World Health Organization about this initiative Dr ghebreyesus replied that this was a very tough move From the perspective of controlling the spread of diseases, such measures are not uncommon "(such an approach) can not only reduce the spread of the disease in China, but also limit its global spread to a minimum." At the press conference, it was also pointed out that at present, the staff of the World Health Organization are studying in China and will also assess the impact of the initiative on local residents If necessary, the World Health Organization will make additional recommendations The novel coronavirus's "human to human transmission" approach is a concern of many journalists during the Q & a session of the press conference Dr Michael Ryan, executive director of the World Health Organization's emergency project, pointed out that after communicating with experts in China, it was confirmed that the disease was spread from person to person, and most of it came from close contacts, such as transmission between family members or between patients and medical staff In terms of human to human transmission, experts are identifying the source of transmission, tracing the transmission chain and finding early cases As for whether there are other ways of communication, we can't make a conclusion at present With regard to the strength of disease transmission, experts said that more data from Wuhan and other surrounding areas are needed to understand the mode of human to human transmission (such as in hospitals or in communities where people live) Only after analyzing the data can we know the infection path of the virus Some reporters also asked at the conference whether the virus would mutate and produce uncontrollable infectious power On this issue, Dr Ryan believes that although there are some variations in the genome of the virus, they have not changed much There is no conclusive evidence of secondary transmission Dr Didier houssin, who expert and chairman of this emergency committee, added: "although we haven't seen much variation at present, the mutation of the virus may occur at any time So we still need to be cautious " At a press conference, a reporter asked about the infected people Dr Ryan replied that from the data of 291 confirmed patients, the disease mainly affects middle-aged and elderly people, and many infected people have other health problems "According to China's data, the virus mainly infects people of a certain age 72% of the infected are over 40 years old, and 64% of the infected are male In addition, 40% of the infected people have underlying health conditions, such as diabetes and high blood pressure In addition, Dr Ryan also pointed out that at present, most of the patients who died of infection have serious underlying diseases "It's just the cases we see, and there's a lot of data we don't know." Dr Ryan added Experts said in a press conference that this is a new pathogen, which can cause a series of symptoms, some mild, some serious We need to identify risk factors related to the severity of symptoms as soon as possible, as well as the ability to carry out virus detection in patients, so that every infected person can be diagnosed, isolated and treated as soon as possible Dr Maria van kerkhove from the Pasteur Institute in France pointed out that after the outbreak of SARS, China has established an active monitoring system for pneumonia Once there are confirmed cases, we can go back for several days to find those medical staff or relatives who have close contact with the infected person This helps to control the disease The lessons we learned novel coronavirus outbreak from the outbreak of SARS and MERS and the advanced technology developed thereby From the perspective of treatment, Dr Ryan reiterated that there is no recognized therapy Although interferon may provide some help, it will also bring some toxicity At present, we can only provide auxiliary treatment support But he also points out that even treatments offered for compassionate purposes can bring us valuable information These data are very important for future clinical trial design At the press conference, some scattered questions were answered When asked about the source of the virus in animals, experts replied that samples were being taken from animals in the seafood market to find the source Whether the disease has a name like SARS and mers is also a topic of concern for some journalists By convention, viruses are named after their original source However, novel coronavirus novel coronavirus is not known as an official name, but is called 2019-nCov, which is the abbreviation of the new coronavirus discovered in 2019 As for whether it can go to China at present, the World Health Organization has no clear proposal Experts attending the press conference also said that they could follow the official website of the World Health Organization at any time to get the latest information On the whole, this press conference did not reveal much new information Dr ghebreyesus also pointed out that more content will be shared after tomorrow's emergency committee meeting "Transparency is very important." Dr ghebreyesus said at the end of the press conference Novel coronavirus outbreak has seen China's scientists complete the sequencing of the virus and shared it for the first time, which has greatly helped Japan, Korea and Thailand The World Health Organization thanks China for its contribution and encourages China to continue to share more information to help reduce the spread of the virus around the world A kind of
