An Outbreak of SARS-CoV-2 in Captive Armadillos Associated with Gamma Variant in Argentina.
EcoHealth(2024)
Abstract
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.
