Abstract

The aim of the research was to carry out a systematic review about the epidemiology of SARS-CoV-2 infection in dogs and cats, as well as the genomic analysis of virus samples isolated from dogs and cats worldwide. For this, the systematic review was structured based on PRISMA’s protocol. Articles were obtained using the following keywords: SARS-CoV-2, COVID-19, dogs, cats, epidemiology, animal transmission, pets, companion animals, animal reservoirs and zoonosis. Additionally, all of SARS-CoV-2 genomes isolated from dogs and cats worldwide, reported in GISAID's EpiCoV™ database, were selected and analyzed through Nextclade’s tool for the generation of the respective phylogenetic trees. The exposure – natural infection with SARS-CoV-2 from January 2020 to October 2021 of 100 dogs and 108 cats positive by the RTq-PCR technique was reported worldwide. Furthermore, 141 SARS-CoV-2 genetic sequences have been isolated from dogs (50) and cats (91), where the following variants monitored by public health organizations were found: the variants of concern (VOC) Alpha, Gamma and Delta, and the variants of interest (VOI) Iota and Lambda. On the other hand, viral lineage B.1. has been predominantly isolated in both dogs and cats (13.3%) and North America is the region with the greatest number of SARS-CoV-2 genomes isolated from both species (43.6%). SARS-CoV-2 has the ability to infect domestic canines and felines, its exposure to VOCs: Alpha, Gamma and Delta, and VOIs: Iota and Lambda being of public health interest; probably due to a "spillover" effect from the human. However, these two species have a low capacity to transmit the virus to other susceptible species, considering that they can act as epidemiological dead-end hosts in the transmission dynamics of SARS-CoV-2.
