●国内是否会二次暴发疫情？钟南山回应

Will there be a second COVID-19 outbreak in China? Zhong Nanshan responded

国内是否会出现疫情的二次暴发？钟南山院士接受央视记者采访时表示：“我估计国内疫情不会出现第二波高峰。在中国群防群控的基础上，新增病例可能就局限在很小的人群中。我不相信在我们这么强有力的措施下，会出现大的暴发。” （央视新闻）

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)

●新冠病毒损伤男性生殖功能？中南医院：论文还未发表，仍在研究阶段

Novel coronavirus injures male reproductive function? Zhongnan Hospital of Wuhan University: the paper has not been published and is still in the research stage

有媒体报道称，性激素水平为新型冠状病毒影响男性性腺提供了首个临床证据。这一临床证据来源于武汉大学中南医院生殖医学中心副教授张铭等人近日在某网站上传的一篇论文，其中列举了81例男性新冠患者的基本数据。中南医院方面回应新京报记者称，关于新冠病毒对男性生殖功能影响的相关研究尚无确切结论，该论文未发表，张铭副教授仍在研究阶段。（新京报）

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)

●6成感染者无症状？专家：隐性感染数据关系到疫情是否会卷土重来

Sixty percent of infected people have no symptoms? Experts: the data on hidden infections are crucial to whether outbreaks will return

华中科技大学公共卫生学院邬堂春团队分析了武汉市卫健委法定传染病报告系统中，截至2月18日的25961例实验室确诊新冠肺炎病例数据。在这些数据的基础上，通过建模分析估计，武汉市至少59的感染病例是未被发现的，其中可能包括无症状和症状轻微的病例。论文认为，对未发现病例进行估计，对持续监测和感染具有重要意义。（中国新闻周刊）

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)

●西湖大学新冠研究登上Science封面，揭秘病毒进入人体那一刻

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)

●如何解读“A型血更易感染新冠肺炎，O型血不易感”？

How to interpret "type A blood is more susceptible to COVID-19, and type O blood is less susceptible"?

据媒体报道，最新研究显示：A、B、O、AB血型与新冠肺炎易感性存在关联。A型血感染新冠肺炎风险相对较高，O型血不易感。首先，这个研究没有正式发表，没有经过同行评议，所以不应被视为结论性的、指导临床实践/健康相关行为的信息。其次，这是一个流行病学的研究结果，表述的是血型与病毒感染的相关性，不能简单做出因果关系的解释。（腾讯较真）

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)

●中科院科研人员发现一类新型微生物命名“中科微菌”

Scientists at the Chinese Academy of Sciences have discovered a new type of microbe named "Casimicrobiaceae"

中国科学院微生物研究所27日发布消息说，该所科研人员最近发现一类广泛存在于城市污水处理系统中的新型微生物，并将其分类命名为“中科微菌”科（Casimicrobiaceae）。科研人员指出，现有研究结果表明，“中科微菌”不仅存于中国污水处理厂，更广泛存在于世界各地的城市污水处理厂活性污泥中。（科学网）

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.
