Transmission of viruses from one species to another is not unusual in nature. Despite this, evolutionarily successful transmissions are rare. Such events can cause pandemics and are followed by host-virus coevolution procedures that can increase the fitness potential of viruses. In this perspective article, I recognize eight main types of trans-species viral transmission. I consider two of them as evolutionarily successful, explaining why coronavirus SARS-CoV-2 could be one of them.
病毒在自然界中从一个物种传播到另一个物种并不罕见。尽管如此，进化上成功的传播却很少见。此类事件会引发大流行，并随之发生宿主-病毒共同进化过程，从而增加病毒的适应潜力。在本文中，我识别了八种主要的跨物种病毒传播类型。我认为其中两种是进化上成功的，解释了为什么冠状病毒 SARS-CoV-2 可能属于其中之一。
