Embecovirus je subgenus koronavirusa u rodu Betacoronavirus. Virusi u ovom podgenusu, za razliku od drugih koronavirusa, imaju gen za hemaglutinin esterazu (HE). Virusi u subgenusu prethodno su bili poznati kao koronavirusi grupe 2a.[1][2]

CoVs are classified into four genera, Alphacoronavirus, Betacoronavirus, Gammacoronavirus and Deltacoronavirus. 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].
