Animals’ susceptibility to SARS-CoV-۲ and their role in the virus transmission, a One Health approach

BACKGROUND AND OBJECTIVESSevere Acute Respiratory Syndrome Coronavirus ۲ (SARS-CoV-۲) was the cause of the Covid-۱۹ pandemic, which faced the world with many challenges. there are many hypotheses about the origin of this virus and most of them imply the animals' role in the transmission of this virus to humans which shows that the virus is zoonotic. Also, following various epidemiological studies conducted in the world, and also the close relationship between humans and animals (especially companion animals), concerns regarding about influential role of animals in transmitting the virus to humans intensified.MATERIALS AND METHODSThe articles have been collected from the PubMed database and Google Scholar. the keywords Covid-۱۹, Animals, Pet animals, One Health, and Zoonosis were used for the search.RESULTS AND DISCUSSIONOverall, it is difficult to determine animals' roles in emerging zoonosis disease because of the lack of evidence, but there have been many seroepidemiological studies related to SARS-CoV-۲ in different animal species due to the importance of this disease. according to the available evidence, ۲۴ different species, including cats (Felis catus), dogs, hamsters, minks, and ferrets, can be sensitive to the virus.CONCLUSIONMany reports are stating that the virus can transmit between animals. cats are one of the most sensitive animals to the virus that are identified. according to this, there are high risks of reverse zoonotic cycles in these animals. moreover, other animals such as hamsters, minks, and ferrets can play important roles in the transmission virus to people. as demonstrated by reports, investigating the role of animals in the Covid-۱۹ epidemic and the level of sensitivity of different animal species is important. based on this, molecular and serological techniques can be very helpful for determining the roles.
