论文摘要
全球严重的急性呼吸道综合征冠状病毒2（SARS-COV-2）感染正在破坏人们的经济和焦虑。公众焦虑增加了政府和医疗保健专业人员的心理负担，导致政府在日本自杀。害怕的人正在向政府采取边界措施。但是，该病毒是否可能采取边界措施？通过分析48个几乎完整的病毒基因组序列，我们发现侵入台湾，美国和日本的病毒被独立引入。我们确定了十三个简约信息和三组（CTC，TCC和TCT）。与先前的研究相反，在中国以外发现的病毒并未形成单系进化枝。这些结果表明，难以针对该病毒实施有效的边界措施。
Worldwide Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is disrupting in the economy and anxiety of people. The public anxiety has increased the psychological burden on government and healthcare professionals, resulting in a government worker suicide in Japan. The terrified people are asking the government for border measures. However, are border measures possible for this virus? By analyzing 48 almost complete virus genome sequences, we found out that the viruses that invaded Taiwan, the United States, and Japan were introduced independently. We identified thirteen parsimony-informative sites and three groups (CTC, TCC, and TCT). Viruses found outside China did not form a monophyletic clade, opposite to previous study. These results suggest the difficulty of implementing effective border measures against this virus.
