新冠病毒的变异毒株D614G已经入侵欧洲、北美和马来西亚、新加坡等亚洲部分地区，据称这种变异毒株的传染性比原病毒高出10倍，还有人担心目前在研发的疫苗可能对变异毒株无效。 A computer image created by Nexu Science Communication together with Trinity College in Dublin, shows a model structurally representative of a betacoronavirus which is the type of virus linked to COVID-19, better known as the coronavirus linked to the Wuhan outbreak, shared with Reuters on February 18, 2020. An increasingly common mutation of the novel coronavirus found in Europe, North America and parts of Asia may be more infectious but appears less deadly, according to a prominent infectious diseases doctor. 一位杰出的传染病医师指出，在欧洲、北美和亚洲部分地区发现的一种日益常见的新冠病毒变异体可能更具传染性，但似乎没有那么致命。 Paul Tambyah, senior consultant at the National University of Singapore and president-elect of the International Society of Infectious Diseases, said evidence suggests the proliferation of the D614G mutation in some parts of the world has coincided with a drop in death rates, suggesting it is less lethal. 新加坡国立大学的高级顾问、国际传染病学会的候任主席保罗·坦布亚表示，有证据显示，D614G变异毒株在世界部分地区扩散的同时，致死率也下降了，这意味着这种新冠病毒变异体没那么致命。 |
