●新冠肺炎导致肺纤维化的概率较低

The probability that COVID-19 causes pulmonary fibrosis is low

北京大学第一医院感染疾病科主任王贵强：新冠肺炎是急性的病毒性传染病，病程较短，导致肺纤维化发展概率比较低，轻型病例大部分不会出现肺纤维化。新冠肺炎对肺脏损害较重，肺部修复过程中会出现纤维组织增生，这是个动态过程，病情不重的很快会被吸收，严重的会残留一些纤维化。（央视新闻）

Wang Guiqiang, director of the department of infetious diseases in the Peking University First Hospital: COVID-19 is an acute viral infectious disease with a short course of disease, which leads to a low probability of pulmonary fhbrosis development. In most mild cases, pumonary fhbrosis will not occur. COVID-19 causes severe damage to the lung, and fibrous tissue hyperplasia wil occur during the repair of the lung. This is a dynamic process, and the mild cases will be absorbed quickly, while the severe cases wil have some residual flbrosis. (CCTV news)

●新研究：对动物源性疾病的监控应扩大到蝙蝠、啮齿动物之外

New research: surveillance for animal-borne diseases should be expanded beyond bats and rodents

蝙蝠和啮齿类动物被认为是高风险的病毒宿主，一些科学家甚至认为，这些动物的某些特征增加了疾病从动物向人类扩散的可能性，因此应对它们进行更密切的监控。但据《自然》报道，一项新的分析表明，蝙蝠和啮齿动物病毒感染人类的倾向“并不特殊”。相关论文日前发表于美国《国家科学院院刊》。（中国科学报）

Bats and rodents are considered high risk virus hosts, and some scientists even believe that certain features of these animals increase the likelihood of disease spreading from animals to humans and should therefore be monitored more closely. But a new analysis shows that bat and rodent viruses are "not unique" in their propensity to infect humans, Nature reports. The paper was published in the Proceedings of the National Academy of Sciences of the United States of America. (sciencenet.cn)
