Embecovirus is a subgenus of coronaviruses in the genus Betacoronavirus.^[1] The viruses in this subgenus, unlike other coronaviruses, have a hemagglutinin esterase (HE) gene.^[2] The viruses in the subgenus were previously known as group 2a coronaviruses.^[3]^[4]

Within Betacoronavirus, they can be further subclassified into lineages A, B, C and D [1]. In 2018, these four lineages were reclassified as subgenera of Betacoronavirus, and renamed as Embecovirus (previous lineage A), Sarbecovirus (previous lineage B), Merbecovirus (previous lineage C) and Nobecovirus (previous lineage D) [2]. In addition, a fifth subgenus, Hibecovirus, was also included (Figure 1) [2].
