Systematic Analysis of the Zoonosis by SARS-CoV-2 in Domestic Cats Under the Concept of One Health

Objective: This study aimed to identify scientific evidence on the zoonotic transmission of SARS-CoV-2 in domestic felines in order to observe the relationship between the susceptibility of cats to SARS-CoV-2, the infection of humans to cats regarding the virus, and the relationship between cat-to-human transmission of SARS-CoV-2. Methods: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Four scientific databases (Google Scholar, Pub- Med, Scielo, and Web of Science) were used for article search, and the review was limited until July 1, 2023. Results: A total of 2327 articles were identified from the three databases, of which 16 were finally included in the review. Eight articles provided information on the high susceptibility of cats to SARS-CoV-2, 7 articles described the characteristics of clinical signs presented in both humans and cats, and only 1 article discussed the infection from a cat to a human. Conclusion: It is important to consider isolating pets during the latency period of the disease within medical recommendations, reinforce the use of eye protection, and adopt the concept of "One Health" to prevent public health problems.
