Template:Coronavirus Betacoronaviruses (β-CoVs or Beta-CoVs) are ane o fower genera (Alpha-, Beta-, Gamma-, an Delta-) o coronaviruses. It is in the subfaimily Orthocoronavirinae in the faimily Coronaviridae, o the order Nidovirales. They are envelopit, positive-sense, single-straundit RNA viruses o zoonotic origin. The coronavirus genera are each componit o varyin viral lineages wi the betacoronavirus genus conteenin fower such lineages: A, B, C, D. In aulder leeteratur, this genus is kent as group 2 coronaviruses an aw.

The Beta-CoVs o the greatest clinical importance concernin humans are OC43 (which can cause the common caud) an HKU1 o the A lineage, SARS-CoV an SARS-CoV-2 (which causes the disease COVID-19) o the B lineage,[3] an MERS-CoV o the C lineage. MERS-CoV is the first betacoronavirus belangin tae lineage C that is kent tae infect humans.[4][5]

The Alphacoronavirus an Betacoronavirus genera strynd frae the bat gene puil.[6][7][8]
