Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) causes the infectious disease COVID-19 (coronavirus disease 2019), which was first reported in Wuhan, China, in December 2019. Despite extensive efforts to control the disease, COVID-19 has now spread to more than 100 countries and caused a global pandemic. SARS-CoV-2 is thought to have originated in bats; however, the intermediate animal sources of the virus are unknown. In this study, we investigated the susceptibility of ferrets and animals in close contact with humans to SARS-CoV-2. We found that SARS-CoV-2 replicates poorly in dogs, pigs, chickens, and ducks, but ferrets and cats are permissive to infection. Additionally, cats are susceptible to airborne transmission. Our study provides insights into the animal models for SARS-CoV-2 and animal management for COVID-19 control.
严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)引起了传染性疾病 2019 冠状病毒病(COVID-19),该病于 2019 年 12 月在中国武汉首次报告。尽管为控制该疾病做出了广泛努力,但 COVID-19 现已传播到 100 多个国家并造成了全球性大流行。据认为,SARS-CoV-2 源自蝙蝠;然而,该病毒的中间动物宿主来源尚不清楚。在这项研究中,我们调查了雪貂和与人类密切接触的动物对 SARS-CoV-2 的易感性。我们发现 SARS-CoV-2 在狗、猪、鸡和鸭中复制能力差,但雪貂和猫容易被感染。此外,猫容易通过空气传播感染。我们的研究为 SARS-CoV-2 的动物模型和 COVID-19 控制的动物管理提供了新的见解。
