HBoV is a putative member of the family Parvoviridae, subfamily Parvovirinae, genus Bocavirus. Before identification of HBoV, parvovirus B19 of the genus Erythrovirus was the only known human pathogen in the family of parvoviruses. Parvovirus B19 is widespread and manifestations of infection vary with the immunologic and hematologic status of the host. In immunocompetent children, parvovirus B19 is the cause for erythema infectiosum. In adults it has been associated with spontaneous abortion, non-immune hydrops fetalis, acute symmetric polyarthropathy, as well as several auto-immune diseases [2, 3, 4, 5] .
