Parechovirus



Parechovirus
Virus classification
Group: Group IV ((+)ssRNA)
Family: Picornaviridae
Genus: Parechovirus
Species

Human parechovirus
Ljungan virus

Parechovirus is a viral genus in the family Picornaviridae. The genus is composed of two species: Human parechovirus and Ljungan virus.[1]

Five types of human parechovirus have been identified: human parechovirus 1 (formerly echovirus 22), human parechovirus 2 (formerly echovirus 23), and human parechoviruses 3, 4 and 5, respectively.[2][3] Human parechoviruses cause mild, gastrointestinal or respiratory illness, but have been implicated in cases of myocarditis and encephalitis. Human parechoviruses are commonly spread and more than 95% of humans are infected by human parechoviruses early in life, within two to five years of age.[4][5]

The Ljungan virus was first isolated from bank voles (Myodes glareolus, formerly Clethrionomys glareolus).[6] Ljungan virus has been proposed as a zoonotic virus, associated with diabetes and intrauterine fetal death in human.[7][8] However, the data regarding these features is currently limited and needs to be confirmed.
