B19 parvovirus (PV) infection is ordinarily resolved with the production of specific antibodies that neutralize virus infectivity for erythroid host cells. Nevertheless persistent infection with B19 PV and pure red blood cell aplasia have been documented. A 27 year-old male. i.v. drug abuser, HIV+ and HCV was diagnosed of pure red cell aplasia. Six months later we had serologic evidence of pers...

Plasma samples obtained at delivery from 885 pregnant Ghanaian women were tested for human parvovirus B19 DNA and B19-specific antibodies. Maternal-fetal transmission was evaluated by testing paired maternal plasma and umbilical cord blood samples, as well as newborn whole-blood samples when they were available. The B19 DNA seroprevalence rate in women was 1.8% (94% had genotype 3 strains), and...

Parvovirus B19 comprises three distinct genotypes (1, 2, and 3). The distribution of B19 genotypes has not before been examined in South Africa. Two hundred thirty-nine laboratory samples submitted to a diagnostic virology laboratory for parvovirus DNA detection were analyzed retrospectively. Of the 53 PCR-positive samples investigated, 40 (75.4%) were identified as genotype 1 by genotype-speci...

PURPOSE: Transient aplastic crisis is reported in an eight-month old child with sickle cell anemia and acute B19 parvovirus infection. This fact is uncommon in this age. PATIENT AND METHODS: The authors review the literature and describe a clinical case of an eight-month old child with sickle cell anemia presented with profound anemia and reticulocytopenia. His peripheral blood was analyzed for...

Human parvovirus B19 infection is occasionally associated with acute lymphocytic myocarditis (ALM). Three infants with B19 virus-associated ALM were followed up clinically, histologically, and immunovirologically. Each infant had B19 virus DNA in the blood or B19 virus-specific IgM antibodies. Two infants with postnatal infection recovered after immunosuppressive therapy. The third infant with ...

Human Parvovirus B19 (B19V) infection usually causes erythema infectiosum (EI). In recent decades, several uncommon exanthems have been described in association with B19V. Recently, haemorrhagic manifestations such as purpuric-petechial rash have been reported. We describe an unusual paediatric case of B19V associated with generalized petechial eruption, and a review of the recent literature.
