“…Bats and birds are natural reservoirs for providing coronavirus and influenza virus genes during the evolution of new virus species and viruses for interspecies transmission ( Chan et al, 2013 ). As described in the latest review ( Tiwari et al, 2020 ), many coronaviruses have bats, birds, or pigs as the primary host, in addition to infecting animals such as civets, pangolins, and camels, coronaviruses also could be harbored by a range of animal species, such as fish, snake, cattle, horse, dog, cat, rabbit, rodent, ferret, minks, frog, marmot, and hedgehog. Moreover, Damas et al (2020) had greatly expanded the potential number of intermediate hosts that might be infected by SARS-CoV-2 through ACE2 receptors by protein structural analysis, which means that plenty of wild animals might be novel SARS-CoV-2 hosts.…”
