The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has lasted for two years and caused millions of infections and deaths in humans. Although the origin of SARS-CoV-2 infection in humans remains unknown, infection in animals has been frequently reported in varieties of animals all over the world. Both experimental and natural infections of SARS-CoV-2 in different animal species provide useful information on viral host range and pathogenicity. As the pandemic continues to evolve, SARS-CoV-2 infection in animals will be expanding. In this review, we summarized SARS-CoV-2 testing and infection in animals as well as SARS-CoV-2 strains and transmission in animals. Current data showed that at least 18 different animal species tested positive for SARS-CoV-2. These 18 animal species belong to pet, captive, farmed, and wild animals. Fifteen of the eighteen animal species were known to be positive for the Delta variant and ten animal species were infected with two different types of variants. Human-to-animal, animal-to-animal, and animal-to-human transmission events were suggested in different outbreaks involved in animal infection with SARS-CoV-2. Continued testing, immunization, and surveillance are warranted.
严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）大流行已经持续了两年，导致数百万人感染和死亡。尽管人类感染 SARS-CoV-2 的起源仍然未知，但世界各地的各种动物中经常报告有动物感染。SARS-CoV-2 在不同动物物种中的实验和自然感染为病毒宿主范围和致病性提供了有用信息。随着大流行的持续演变，动物中的 SARS-CoV-2 感染将会扩大。在这篇综述中，我们总结了 SARS-CoV-2 在动物中的检测和感染，以及动物中的 SARS-CoV-2 株和传播。目前的数据表明，至少有 18 种不同的动物物种对 SARS-CoV-2 检测呈阳性。这 18 种动物属于宠物、圈养、养殖和野生动物。在涉及 SARS-CoV-2 感染的动物的不同暴发中，有 15 种动物物种被证实为 Delta 变体阳性，10 种动物物种感染了两种不同类型的变体。在涉及 SARS-CoV-2 感染的动物的不同暴发中，建议存在人传动物、动物传动物和动物传人事件。需要继续进行检测、免疫和监测。
