SARS-CoV-2 zoonotic potential is discussed in this Chapter. COVID-19 demonstrates the failure of biosafety and security systems and safeguards that should prevent a global pandemic of this emergency. According to researchers, zoonotic diseases will continue to cross the animal-human barrier causing the additional risks for emergency. SARS‐CoV‐2 pandemic spread covered over 800 million cats and dogs kept as pets worldwide, as well as large segment of animal farming industry, that raises concerns of domestic and farmed animals in general and carnivores in particular, becoming an epidemiologically relevant animal source for COVID‐19. SARS‐CoV‐2 control strategies have to pay attention to the close interaction between humans and companion or farmed animals contributes to human infections. The SARS‐CoV‐2 mitigation strategies have to take into the account the existing zoonotic transmission, and should be developed in a One Health framework, implementing molecular and serological surveillance as well as epidemiological assessment of SARS‐CoV‐2 occurrence in domestic and farmed animals alongside humans.

The complete genome of Salmonella enterica subsp. enterica serovar Kottbus (serogroup C2-C3), which was isolated from a commercial pork production facility in Kharkiv, Ukraine, was assembled using long-read Nanopore sequences. A single circular contig (4,799,045 bp) comprised a complete chromosome encoding antibiotic resistance, highlighting the risk of cross-species livestock and human infection.

The Coronavirus Disease 2019 (COVID-19) is the first known pandemic caused by a coronavirus. Its causative agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), appears to be capable of infecting different mammalian species. Recent detections of this virus in pet, zoo, wild, and farm animals have compelled inquiry regarding the zoonotic (animal-to-human) and reverse zoonotic (human-to-animal) transmissibility of SARS-CoV-2 with the potential of COVID-19 pandemic evolving into a panzootic. It is important to monitor the global spread of disease and to assess the significance of genomic changes to support prevention and control efforts during a pandemic. An understanding of the SARS-CoV-2 epidemiology provides opportunities to prevent the risk of repeated re-infection of humans and requires a robust One Health-based investigation. This review paper describes the known properties and the existing gaps in scientific knowledge about the zoonotic and reverse zoonotic transmissibility of the novel virus SARS-CoV-2 and the COVID-19 disease it causes.
