Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a zoonotic virus able to infect humans and multiple nonhuman animal species. Most natural infections in companion, captive zoo, livestock, and wildlife species have been related to a reverse transmission, raising concern about potential generation of animal reservoirs due to human–animal interactions. To date, American mink and white-tailed deer are the only species that led to extensive intraspecies transmission of SARS-CoV-2 after reverse zoonosis, leading to an efficient spread of the virus and subsequent animal-to-human transmission. Viral host adaptations increase the probability of new SARS-CoV-2 variants’ emergence that could cause a major global health impact. Therefore, applying the One Health approach is crucial to prevent and overcome future threats for human, animal, and environmental fields.

严重急性呼吸系统综合征冠状病毒2从人类传播给动物:是否存在新的宿主风险?
严重急性呼吸系统综合征冠状病毒2型(SARS-CoV-2)是一种人畜共患病毒,能够感染人类和多种非人类动物。伴侣、圈养动物园、牲畜和野生动物物种的大多数自然感染都与反向传播有关,这引发了人们对人与动物相互作用可能产生动物宿主的担忧。迄今为止,美国水貂和白尾鹿是唯一一种在逆转人畜共患病后导致严重急性呼吸系统综合征冠状病毒2型在种内广泛传播的物种,从而导致病毒的有效传播和随后的动物间传播。病毒宿主的适应增加了新的严重急性呼吸系统综合征冠状病毒2型变种出现的可能性,这可能会对全球健康造成重大影响。因此,应用“一个健康”方法对于预防和克服人类、动物和环境领域的未来威胁至关重要。

期刊介绍: Current Opinion in Virology (COVIRO) is a systematic review journal that aims to provide specialists with a unique and educational platform to keep up to date with the expanding volume of information published in the field of virology. It publishes 6 issues per year covering the following 11 sections, each of which is reviewed once a year: Emerging viruses: interspecies transmission; Viral immunology; Viral pathogenesis; Preventive and therapeutic vaccines; Antiviral strategies; Virus structure and expression; Animal models for viral diseases; Engineering for viral resistance; Viruses and cancer; Virus vector interactions. There is also a section that changes every year to reflect hot topics in the field.
