Will there be a second COVID-19 outbreak in China? Zhong Nanshan responded
Will there be a second COVID-19 outbreak in China? "I don't think there will be a second wave of outbreaks in China," Zhong Nanshan told CCTV. On the basis of mass prevention and control in China, new cases may be confined to a small population."I do not believe that there will be a major outbreak with our strong measures." (CCTV news)
WHO: covid-19 vaccine development is still 12 to 18 months away
The World Health Organization (WHO) has warned that it will take at least 12 to 18 months to develop a covid-19 vaccine, and that all individuals and countries should not use unproven treatments. (xinhua)
Novel coronavirus injures male reproductive function? Zhongnan Hospital of Wuhan University: the paper has not been published and is still in the research stage
The first clinical evidence of a novel coronavirus affecting the male gonad has been reported. The clinical evidence comes from a paper recently uploaded on a website by Zhang Ming, associate
professor of reproductive medicine at Zhongnan Hospital of Wuhan University, which listed the basic data of 81 male patients with the novel coronavirus. Zhongnan Hospital responded to the Beijing news, saying that there is no definite conclusion on the research on the effect of novel coronavirus on male reproductive function. The paper has not been published and associate professor Zhang Ming is still in the research stage. (bjnews.com)
Sixty percent of infected people have no symptoms? Experts: the data on hidden infections are crucial to whether outbreaks will return
Wu Tangchun team of the school of public health at Huazhong University of Science and Technology analyzed data from 25,961 laboratorially confirmed COVID-19 cases in the Wuhan Health Commission's statutory infectious disease reporting system as of Feb.18. Based on these data, a modeling analysis estimated that at least 59 cases of infection in Wuhan were undetected, which may include asymptomatic and mild cases. The paper believes that the estimation of undetected cases is of great significance for continuous surveillance and infection. (inewsweek.cn)
Westlake University's novel coronavirus study made the
cover of Science, revealing the moment the virus entered the human body
西湖大学周强实验室在论文《Structural basis for the recognition of the SARS-CoV-2 by full-length human ACE2》中，首次公开了新型冠状病毒表面 S 蛋白受体结合结构域与细胞表面受体 ACE2 全长蛋白复合物的三维结构，展示了新冠病毒侵染人体细胞的详细过程。随着新冠肺炎在全球范围内逐渐呈现大流行趋势，这一研究内容对新冠肺炎的精准诊断及治疗起到了重要的推动作用。（机器之心）
In the paper "Structural basis for the recognition of the sars- cov-2 by full -length human ACE2", Zhou Qiang laboratory of Westlake University first disclosed the three-dimensional structure of the S protein receptor binding domain on the surface of novel coronavirus and the full-length protein complex of the cell surface receptor ACE2, demonstrating the detailed process of novel coronavirus infection of human cells. As COVID-19 gradually presents a global pandemic trend, this research content plays an important role in promoting the accurate diagnosis and treatment of COVID-19. (jiqizhixin.com)
How to interpret "type A blood is more susceptible to COVID-19, and type O blood is less susceptible"?
According to media reports, the latest research shows that A, B, 0 and AB blood types are associated with covid-19 susceptibility. The risk of COVID-19 infection in type A blood is relatively high and type 0 blood is not susceptible. First, the study was not formally published and peer-reviewed, so it should not be considered conclusive information that guides clinical practice/health-related behavior. Second, this is an epidemiological study showing a correlation between blood types and viral infections, not a simple cause-and-effect explanation. (vp.fact.qq.com)

Scientists at the Chinese Academy of Sciences have discovered a new type of microbe named "Casimicrobiaceae"
Researchers at the Institute of Microbiology of the Chinese Academy of Sciences (CAS) have identifed a new type of microbe widely found in urban sewage treatment systems and have classifed it as Casimicrobiaceae, the institute said on March 27. The researchers point out that the existing research results show that the "Casimicrobiaceae" not only exists in China's sewage treatment plants, but also in the activated sludge of municipal sewage treatment plants around the world.
