Human parvovirus B19, generally referred to as B19 virus (B19V), parvovirus B19[1] or sometimes erythrovirus B19,[2] is a known human virus in the family Parvoviridae, genus Erythroparvovirus; it measures only 23–26 nm in diameter.[3] Human parvovirus b19 is a below-species classification of Erythroparvovirus primate1.[4] The name is derived from Latin parvum, meaning small, reflecting the fact that B19 ranks among the smallest DNA viruses. B19 virus is most known for causing disease in the pediatric population; however, it can also affect adults. It is the classic cause of the childhood rash called fifth disease or erythema infectiosum, or "slapped cheek syndrome".[5][6] The name comes from it being the fifth in a list of historical classifications of common skin rash illnesses in children.[7]
