Human CoV-OC43 (HCoV-OC43) is one of the four common human CoVs that can cause seasonal mild to moderate respiratory diseases in humans. In this study, we identified HCoV-OC43 for the first time in two asymptomatic pet hamsters, which share a high similarity with the human-derived HCoV-OC43 strain, suggesting potential cross-species transmission of HCoV-OC43 to pet hamsters. The finding emphasizes the need to strengthen pathogen monitoring of livestock and pets in close contact with humans to provide early warning of public safety.
