The current pandemic produced by SARS-CoV-2 and its variants represent an example of the one health concept in which humans and animals are components of the same epidemiologic chain. Animal reservoirs of these viruses are thus the focus of surveillance programs, to monitor their circulation and evolution in potentially new hosts and reservoirs. In this work, we report the detection of the SARS-CoV-2 Gamma variant infection in four specimens of Chaetophractus villosus (big hairy armadillo/armadillo peludo) in Argentina. In addition to the finding of a new wildlife species susceptible to SARS-CoV-2 infection, the identification of the Gamma variant three months after its last detection in humans in Argentina is a noteworthy result, which can be due to alternative non-exclusive scenarios, such as unidentified viral reservoirs, unrecognized circulation in humans or species-specific variation in incubation periods.
由严重急性呼吸综合征冠状病毒2（SARS-CoV-2）及其变体引发的当前大流行体现了“同一健康”概念，即人类和动物是同一流行病学链条的组成部分。因此，这些病毒的动物宿主成为监测计划的重点，以监测它们在潜在新宿主和宿主群体中的传播及演变。在本研究中，我们报告了在阿根廷的四个长毛犰狳（Chaetophractus villosus）样本中检测到SARS-CoV-2伽马变体感染。除了发现一种新的易感染SARS-CoV-2的野生动物物种外，在阿根廷最后一次在人类中检测到伽马变体三个月后在犰狳中鉴定出该变体，这一结果值得关注，其原因可能是多种非排他性情况，如未识别的病毒宿主、在人类中未被认识到的传播或潜伏期的物种特异性差异。
