The genus is composed of two species: Human parechovirus and Ljungan virus.Six types of human parechovirus have been identified: human parechovirus 1 (formerly echovirus 22), human parechovirus 2 (formerly echovirus 23), and human parechoviruses 3, 4, 5 and 6, respectively. 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.
