Coronaviruses are highly pathogenic and therefore important human and veterinary pathogens viruses worldwide. Members of family Coronaviridae have previously been analysed phylogenetically, resulting in proposals of virus interrelationships. However, available Coronavirus phylogenies remain unrooted, based on limited sampling, and normally depend on a single method. The main subjects of this study are the taxonomy and systematics of coronaviruses and our goal is to build the first natural classification of Coronaviridae using several methods of cladistic analyses, Maximum Likelihood method, as well as rigorous taxonomic sampling, making the most accurate representation of Coronaviridae s relationships to date. Nomenclature recommendations to help effectively incorporate principles of binary nomenclature into Coronaviridae taxonomy are provided. We have stressed that no member of Sarbecovirus clade is an ancestor of SARS Cov 2, and humans are the only known host.

关于冠状病毒（核病毒，尼多韦拉氏，冠状病毒科）的分类和分类，特别关注与严重急性呼吸综合征相关的冠状病毒2（SARS-Cov-2）

冠状病毒是高致病性的，因此是全世界重要的人类和兽医病原体病毒。冠状病毒科的成员以前已经进行了系统发育分析，从而提出了病毒相互关系的建议。但是，基于有限的采样，可用的冠状病毒系统发育史仍然是无根的，通常取决于一种方法。这项研究的主要主题是冠状病毒的分类学和系统学，我们的目标是使用数种分类分析方法，最大似然法以及严格的分类学抽样方法建立冠状病毒科的第一个自然分类，从而最准确地表示冠状病毒科迄今为止的关系。提供了命名建议，以帮助将二元命名原则有效地纳入冠状病毒科分类法中。
