Abstract
Canine enteric coronavirus (CCoV) is a pathogenic virus that infects dogs worldwide, causing enteric issues and causing harm to the dog industry and dogs. Although CCoV is not recognized as a highly lethal canine intestinal pathogen, it has been reported that CCoV is significantly associated with canine diarrhea in dogs. CCoV is a common health problem in dogs, attracting major concern from veterinarians and dog owners across China. In this study, we summarized the prevalence and epidemiological characteristics of CCoV in dogs in mainland China. The study revealed that the pooled prevalence of CCoV infection was 33%, and which associated with age, but not with sex, season and immunization status. In addition, the study also further suggested that CCoV-II was the predominant CCoV subtype in Chinese dogs. This study will provide valuable information for CCoV infections across China and other countries. Furthermore, this study also suggested that continuous surveillance and epidemiological studies of CCoV are necessary.
