Abstract
Objective: In the twenty-first century, despite the development in infection management, and improvement of vaccines and therapeutic agents in the field of health, new viral outbreaks that can still be fatal in humans and animals are emerging. The infection of zoonosis COVID-19 from bat origin, the intermediate host of which is still being unclear, has appeared in people who visited animal bazaar in December 2019, in Wuhan, China. The World Health Organization declared this infection a pandemic in February 2020. Millions of people have been affected by this pandemic. The fight against the pandemic has had a great economic cost and continues to do so. Even people have changed their lifestyle. In this context, there have been concerns about companion animals with COVID-19 transmission, from human to animal or animal to human. The purpose of this review was to examine the studies on the presence and transmission of COVID-19 in companion animals such as cats, dogs, hamsters and horses.
Result and Discussion: It has been reported in studies that most of the companion animals (cat, dog and hamster) were susceptible to SARS-CoV-2, and humans could be a source of infection for them. However, the potential role of companion animals in transmission to humans is not fully known. It is clear from this pandemic that the necessity of epidemiological investigation of infectious agents, especially zoonotic ones, in one health concept has emerged once again.
