Nasopharyngeal swabs were obtained from 210 of the 211 women (99.5%) who did not have symptoms of Covid-19; of these women, 29 (13.7%) were positive for SARS-CoV-2. Thus, 29 of the 33 patients who were positive for SARS-CoV-2 at admission (87.9%) had no symptoms of Covid-19 ...
The evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus leads to new variants that warrant timely epidemiological characterization. Here we use the dense genomic surveillance data generated by the COVID-19 Genomics UK
Because the number of confirmed infections of COVID-19 is higher than the total number of suspected SARS cases, the novel coronavirus is assumed to be more contagious than SARS with respect to community spread and severity (De Wit et al., 2016). Consequently, the novel CoV is currently ...
我们不禁要问,新型冠状病毒(Novel Coronavirus,2019-nCoV,国际病毒分类委员会(ICTV)将新型冠状病毒命名为SARS-CoV-2,目前学界尚有争议,中国专家呼吁命名为HCoV-19,我们暂用大家所熟悉的新型冠状病毒这一名称)是怎么来的,接下来疫情会如何发展,为了避免新的疫情发生...
The world is combating an ongoing COVID-19 pandemic with health-care systems, society and economies impacted in an unprecedented way. It is unclear how many people have contracted the causative coronavirus (SARS-CoV-2) unknowingly and are asymptomatic. T
“大量需求快把我们淹没了。”杰克逊实验室负责小鼠储备的神经科学家 Cathleen Lutz 说。目前,他们已经收到了约 50 个实验室的订单,需要超过 3000 只转基因小鼠。转基因小鼠含有人源 ACE2,这也是新冠病毒(SARS-CoV-2)借以进入细胞的...
COVID-19本身是一种新发病毒病,由于2019-nCoV具有传播能力强、病毒携带者症状隐秘等特点,给防控造成很大困难,如果要让2019-nCoV像SARS-CoV一样销声匿迹,恐怕要付出更大的努力。笔者认为,与流行性感冒病毒相比,新型冠状病毒由于缺乏与人类关系密切的自然病毒宿主,可能不会发展成为一种季节性的流行病。长远来看,如果无...

为什麽呢?除了上述提到的,关于月桂叶精油的化合物分子『氧化物』有助于缓解呼吸道感染之外,最重要的数据是来自于2008年的一项针对7种黎巴嫩精油所做的研究,显示月桂浆果精油因富含1,8 桉油醇, β-罗勒烯, α-蒎烯, β-蒎烯等化合物分子,在7种精油中对抗SARS-CoV病毒的表现最优秀。
