The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging zoonotic virus of public and
animal health concern, of which felids have been suggested as potential reservoirs. Although SARS-CoV-2
exposure has been detected in domestic and wild captive animals belonging to Felidae family, surveillance has
not been carried out in free-ranging wild felids so far. The aim of the present study was to assess SARS-CoV-2
exposure in the Iberian lynx (Lynx pardinus), the most endangered felid in the world. Between 2019 and
2022, we conducted a seroepidemiological study of SARS-CoV-2 in 276 free-ranging and captive Iberian lynxes.
Our results evidenced limited (0.4%; 95%CI: 0.0–1.1) but not negligible exposure to this emerging virus in this
endangered felid species, increasing the SARS-CoV-2 host range. The circulation of this virus in wildlife evidences the need of integrated European wildlife monitoring.This study is part of the TED2021-132599B-C22 project, funded by MCIN/AEI/10.13039/501100011033 and by the European Union "NextGenerationEU"/PRTR.
