The largest new crown research ever published by China CDC: the first time to describe the epidemic curve, the overall mortality rate is 2.3%, more than 3000 medical and nursing infections

Before the beginning of the text, I would like to say today's bad news and good news: "the first hospital director in Wuhan died", which is today's first bad news Novel coronavirus pneumonia was forenoon at 10:30 a.m on February 18th, Liu Zhiming, director of the Wuhan Wuchang hospital and Department of Neurosurgery expert, died in the new town hospital of Tongfa hospital He was also the first serving president to die in the new crown Novel coronavirus pneumonia is reported to be 6 in Wuhan, so far, only 5 people are doctors in Department of ENT, Hubei provincial integrative medicine hospital, Liang Wudong, Wuhan eye hospital doctor of Central Hospital of Hubei, Professor Lin Zhengbin of organ transplantation Institute of Tongji Hospital Affiliated to Huazhong University of Science and Technology, and Ezhou Chinese medicine Xu Defu, former dean of the hospital, Liu fan, nurse of injection room of Liyuan street community health service center of Wuhan Wuchang hospital Novel coronavirus infection prevention team leader and vice president Xu Hui, Taizhou People's Hospital of Nanjing Taizhou People's Hospital, and other infectious diseases doctors in Taizhou People's Hospital, Jiangsu, have also been killed in the fight against epidemic diseases This is a long list of heartbreaking The dawn of victory is not far away, but they will never see it again Please remember their names forever Achieve "Three Firsts" and improve the epidemic situation On February 18, at the press conference of the joint prevention and control mechanism of the State Council, MI Feng, spokesman of the national health and Health Commission and deputy director of the publicity department, said that compared with the high point, the number of newly confirmed cases in a single day fell to less than 2000 for the first time in China on February 17, to less than 100 for the first time in a single day outside Hubei Province, and to less than 100 for the first time in a single day in China Second, the epidemic situation has further changed to a better one If we continue to maintain this positive momentum, the victory in the fight against the epidemic will not be far away The free air and sunshine outside are waving to us China novel coronavirus novel coronavirus pneumonia epidemiological analysis published in novel coronavirus pneumoniae in February 17th was published in the latest issue of the Chinese Journal of epidemiology The report was written by the epidemiology team of the new type coronavirus pneumonia emergency response mechanism of the China Center for Disease Control and Prevention (CDC), published in the February 17th The report first described novel coronavirus pneumonia epidemic curve in 2019, and pointed out that the epidemic was mainly spread in small areas in December, and then spread in January However, the time of diagnosis reached its peak in from January 23rd to 27th, and the high incidence of single day disease has gradually declined since February 1st This means that the epidemic has been effectively controlled The novel coronavirus infection (including confirmed cases, suspected cases, clinical diagnosis cases and asymptomatic infections), including 1716 confirmed cases, may be infected by 3019 new medical staff As of February 11th, there may be infection caused by non occupation exposure The report also reminded that some areas in Wuhan and Hubei had serious medical staff infection, but so far, the specific causes of medical staff infection and protection failure still need to be further investigated Novel coronavirus pneumonia is 1 The total mortality rate is 2.3%, male 2.8%, female 1.7% As of February 11th, 72314 cases were reported in mainland China, 44672 cases (61.8%) were diagnosed with new crown pneumonia, 16186 cases (22.4%) were suspected cases, 10567 cases (14.6%) were diagnosed clinically, and 22.4% cases (asymptomatic) were asymptomatic Among the confirmed cases, most of them were between 30 and 69 years old (77.8%), 51.4% were male, 22.0% were farmers or workers, 74.7% were Hubei Province, 80.9% were mild Through the analysis of more than 70000 cases, it is found that most of the patients are aged 30-79 years, accounting for 89.8% of the total confirmed cases in Wuhan, 88.6% in Hubei Province (including Wuhan), and 86.6% in the whole country (including Hubei) The proportion of cases in the elderly group over 60 years old is 44.1% in Wuhan, 35.1% in Hubei (including Wuhan) and 31.2% in China (including Hubei) The ratio of male to female was 0.99:1 in Wuhan, 1.04:1 in Hubei and 1.06:1 in China From the data point of view, there is no significant gender difference in the confirmed cases Of the 44672 confirmed cases, 1023 died, with a total mortality rate of 2.3%, of which the highest crude mortality rate was 14.8% in the two groups over 80 years old However, the mortality rate of male was 2.8% and that of female was 1.7% The mortality rate of male was significantly higher than that of female It is worth mentioning that the reported data show that the mortality rate of Hubei Province is 2.9%, 7.3 times higher than that of other provinces (0.4%) Novel coronavirus pneumonia novel coronavirus pneumonia patients were also reported The report also pointed out that the fatality rate of patients without complications was about 0.9%, and the mortality of patients with complications was much higher: 2 The first time the epidemic curve of 2019 new crown pneumonia was first described The date of onset of the reported cases was retrospectively analyzed The overall curve shows an outbreak epidemic mode From the data, the cases in December 2019 may be a small-scale exposure transmission mode From January 2020 to February 11, 2020, it may be a diffusion mode The novel coronavirus is likely to be infected with wild animal animal products from a wild animal that is still unknown to humans in Wuhan, Southern China In addition, the epidemic curve also showed that the onset time of confirmed cases peaked from January 24 to 28, and then decreased slowly, but on February 1, there was an abnormal high value of single day onset, and then decreased gradually 3 3019 medical staff were infected The cause of the infection needs further investigation The paper analyzed the cases outside Hubei Province, and drew the epidemic curve according to the date of the onset of the disease It showed that the peak of the incidence of cases outside Hubei Province was from January 24 to 27 Most of the cases (68.6%) lived or visited Wuhan within 14 days before the onset of the disease, or had close contact with Wuhan patients A novel coronavirus infection (1716 confirmed cases) has been reported in 3019 papers, as of February 11, 2020 According to the analysis of 1688 confirmed cases with severity, there are 1080 cases in Wuhan, accounting for 64.0% of the total number of medical staff in China The report points out that some areas in Wuhan and Hubei have suffered from serious infection of medical staff, which may be caused by non occupational exposure But up to now, the specific causes of infection and failure of protection of medical staff still need to be further investigated Novel coronavirus pneumonia is also a special reminder that although the epidemic situation has been decreasing in February 11th, the epidemic has not yet ended, especially after a large number of staff flow and contacts after resuming work, which has increased the risk of transmission of new crown pneumonia We must continue to implement the first case finding and disposal of the community and labor place as a unit, and prevent the outbreak of the epidemic It is worth mentioning that on February 18, at a press conference held by the Information Office of the Guangdong provincial government, Zhong Nanshan, head of the high level expert group of the national health and Health Commission and academician of the Chinese Academy of engineering, also mentioned that the number of confirmed cases in China has declined, but Wuhan is still the key In addition, Zhong also stressed that in daily protection, besides wearing masks and washing hands frequently, sewer channels are extremely important In Hong Kong, there were cases of diseases both upstairs and downstairs (add: on February 10, the 42nd new case confirmed in Hong Kong and the 12th case confirmed previously lived in room 07 of the same building In view of this, the Hong Kong SAR government also evacuated the residents of the building in the early morning of February 11.) This shows that the lesson of SARS Taoda garden in 2003 is still useful At that time, more than 200 people in the same building got sick and more than 20 people died Who survey found that one of the ways to spread the virus upstairs and downstairs in Taoda garden is the sewer At present, the novel coronavirus pneumonia and the Li Lanjuan's team have detected the virus from the feces of the new crown pneumonia patients, which means that the new crown virus does not necessarily spread through the digestive tract "The new coronavirus does not necessarily spread through the digestive tract, but because the pollutants in the sewer are dry and spread through the air and aerosols People inhale it to cause infection, so we must ensure that the toilet sewer is unobstructed." Zhong Nanshan explained Penicillin
