The genus Cardiovirus consists three species, Cardiovirus A (formerly named Encephalomyocarditis virus), Cardiovirus B (formerly named Theilovirus) and Cardiovirus C. Cardiovirus A is comprised of two serotypes of encephalomyocarditis virus (EMCV). Cardiovirus B is comprised of Theiler's murine encephalomyelitis virus (TMEV), Vilyuisk human encephalomyelitis virus (VHEV), Thera virus (TRV;  isolated from rats), Saffold virus (SAFV; isolated from humans) 1-11. Cardiovirus C is comprised of Boone cardiovirus 1 and 2. The cardioviruses are most closely related to members of the genera , Aphthovirus, Cosavirus, Erbovirus and Senecavirus.
