<unk>  (β-CoVs or Beta-CoVs) is one of four genera (Alpha-, Beta-, Gamma-, and Delta-) of coronaviruses. Member viruses are enveloped, positive-strand RNA viruses that infect mammals (of which humans are part). The natural reservoir for<unk> es are bats and rodents. Rodents are the reservoir for the subgenus Embecovirus, while bats are the reservoir for the other subgenera. The coronavirus genera are each composed of varying viral lineages with the<unk>  genus containing four such lineages: A, B, C, D. In older literature, this genus is also known as "group 2 coronaviruses". The genus is in the subfamily Orthocoronavirinae in the family Coronaviridae, of the order Nidovirales. The<unk> es of the greatest clinical importance concerning humans are OC43 and HKU1 (which can cause the common cold) of lineage A, SARS-CoV and SARS-CoV-2 (which causes the disease COVID-19) of lineage B, and MERS-CoV of lineage C. MERS-CoV is the first<unk>  belonging to lineage C that is known to infect humans.
