The virus has coevolved in the bat host reservoir over a long period of time. [17] Only recently have strains of SARS-related coronavirus been observed to have evolved into having been able to make the cross-species jump from bats to humans, as in the case of the strains SARS-CoV-1 and SARS-CoV-2 .
The betacoronaviruses of the greatest clinical importance concerning humans are OC43 and HKU1 (which can cause the common cold) of lineage A, SARS-CoV-1 and SARS-CoV-2 (the causes of SARS and COVID-19 respectively) of lineage B, [2] and MERS-CoV (the cause of MERS) of lineage C. MERS-CoV is the first betacoronavirus belonging to lineage C that ...
The human virome is a part of human bodies and will not always cause harm. [23] Many latent and asymptomatic viruses are present in the human body all the time. Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in the gut also carry viruses. [ 6 ]
RaTG13 has not been confirmed to exist in nature, to have been cultured or isolated in any laboratory, [12] or to be a viable human pathogen. [16] A live virus "RaTG13" has never been detected in any laboratory sample from the WIV or elsewhere. [16] Based on its sequence, RaTG13 is a positive-strand RNA virus with an outer membrane. Its genome ...
SARS-CoV-2 shares amino acid identity with a furin cleavage site of human ENaC α subunit. [30] [31] [b] Human ENaC is identical only to that of a few great apes and Pipistrellus kuhli. [32] SARS-CoV-2 is also distinct among human coronaviruses for having a single intact ORF8 gene rather than "a" and "b" subunits. [1]

The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans. The Centers for Disease Control and Prevention has stated that there is low risk that the virus would spread from animals to people but further studies are yet to be conducted ...
Bat SARS-like coronavirus WIV1 (Bat SL-CoV-WIV1), also sometimes called SARS-like coronavirus WIV1, is a strain of severe acute respiratory syndrome–related coronavirus (SARSr-CoV) isolated from Chinese rufous horseshoe bats in 2013 (Rhinolophus sinicus).
