ABSTRACT
Several human coronaviruses cause high mortality rates and are highly contagious, while others cause cold-like illnesses. These viruses are believed to enter human populations by zoonotic transmission from animal intermediate hosts from live animal markets in China [severe acute respiratory syndrome coronaviruses (SARS-CoV) from palm civets/raccoon dogs and SARS-CoV-2 possibly from pangolins] or dromedary camels in the Arabian Peninsula (Middle East respiratory syndrome coronavirus). Some bats may act as reservoir hosts. While much focus on the possible reservoir and intermediate hosts for future zoonotic transmission focuses on bats or rodents, humans spend much more time with agricultural animals, including cattle, pigs, camelids, and horses, particularly pigs, which host six coronaviruses. One pig coronavirus is a deltacoronavirus, a genus that almost exclusively contains bird viruses. The species Betacoronavirus-1, represented by a bovine coronavirus, contains members that infect other animal hosts, as do the Alphacoronavirus-1 species. Humans spend large amounts of time in the company of their companion animals, such as cats and dogs. Some contact is intimate, including allowing these animals to sleep with their owners and lick their faces. In addition to possible zoonotic transmission, humans transmit coronaviruses, including SARS-CoV-2, to domestic and captive exotic cats, some of which are endangered. Human-to-cat transmission of SARS-CoV-2 has caused severe disease in juvenile domestic cats. People are also regularly in contact with animal fecal material. Some diseases caused by animal coronaviruses are typically mild, while others cause severe, life-threatening diseases. Both morbidity and mortality in agricultural animals have a great economic impact on developing and developed regions of the world. Due to close, prolonged contact between humans and agricultural and companion animals, it may be a matter of great importance to spend more time and resources studying the potential for coronaviruses of domestic animals to cause zoonotic transmission.
