There are numerous cornaviruses that infect humans as well as bats and birds, and have done so for thousands of years at least. Animal-to-human transfer of novel viruses is by far the most common cause of novel epidemics.

>Many human coronaviruses have their origin in bats.[75] The human coronavirus NL63 shared a common ancestor with a bat coronavirus (ARCoV.2) between 1190 and 1449 CE.[76] The human coronavirus 229E shared a common ancestor with a bat coronavirus (GhanaGrp1 Bt CoV) between 1686 and 1800 CE.
