根据nature网站的2020六月的文章” The biggest mystery: what it will take to trace the coronavirus source“https://www.nature.com/articles/d41586-020-01541-z,病毒来源现在仍是一个最大的谜团,大多数研究者认为根据现有信息,更可能的解释是病毒来源于蝙蝠,传给中间宿主,再传播到人。但要排除病毒来源于实验室(含武汉病毒所)的唯一方法,可能就是去实验室进行独立调查,但目前无法做到这一点。(most researchers say the more likely explanation, given what is known so far about this virus and others like it, is that bats passed it to an intermediate animal, which then spread it to people.
An independent investigation at the facility (WIV) is probably the only way to convincingly rule out the lab as a possible source of the outbreak, but scientists think such a probe is unlikely, given the delicate geopolitics that surround the issue.)
请注意其标题和结论:现有证据表明病毒不是经过人工改造的,但目前不可能证明或否认病毒其它来源的可能性,我们不相信病毒是经过实验室改造的。(Although the evidence shows that SARS-CoV-2 is not a purposefully manipulated virus, it is currently impossible to prove or disprove the other theories of its origin described here. However, since we observed all notable SARS-CoV-2 features, including the optimized RBD and polybasic cleavage site, in related coronaviruses in nature, we do not believe that any type of laboratory-based scenario is plausible.)
