Other subfamily Parvovirinae members known to infect humans are the apathogenic adenoassociated viruses of the genus Dependovirus and parvovirus 4 [6, 7] . Parvovirus 4 has not yet been assigned to a genus, but it was proposed to allocate it to the genus Hokovirus as it shares more similarities to the novel porcine and bovine hokoviruses than with other parvoviruses [8] . Recently a second human bocavirus has been identified, HBoV2, with 75.6 % nucleotide similarity to HBoV [9] . HBoV2 was found in stool samples from Pakistani children as well as in samples from Edinburgh (1 of the 3 positive samples was derived from a patient >65 years old), indicating that it is not restricted to one region or to young children.
