The species Human parechovirus (proposed new species name "Parechovirus A") consists of 16 types, HPeV-1 to 16. HPeV-1 and HPeV-2, were formerly classified in the enterovirus genus as echovirus 22 and 23, respectively. Another isolate, CT86-6760, originally classified as E-23/HPeV-2 (based on serological cross-reactions) has been re-classified as HPeV-5.
