''Parechovirus'' is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Bank voles and humans serve as natural hosts. There are currently only two species in this genus including the type species ''Parechovirus A'', also called human parechoviruses and ''Parechovirus B'', more commonly known as the ''Ljungan virus''.〔(【引用サイトリンク】 Parechovirus )〕 Diseases associated with this genus include: human parechoviruses: mild, gastrointestinal or respiratory illness, have been implicated in cases of myocarditis and encephalitis; Ljungan virus: may be a zoonotic virus associated with diabetes and intrauterine fetal death in human. 〔(【引用サイトリンク】url=http://viralzone.expasy.org/all_by_species/657.html )〕〔(【引用サイトリンク】title=Virus Taxonomy: 2014 Release )〕 ==Taxonomy== Group: ssRNA(+) }}〔 Six types of human parechovirus have been identified: human parechovirus 1 (HPeV1, formerly echovirus 22), human parechovirus 2 (formerly echovirus 23), and human parechoviruses 3, 4, 5 and 6.〔Watanabe K, Oie M, Higuchi M, Nishikawa M, Fujii M.
