Human parvovirus B19

Primate erythroparvovirus 1, generally referred to as B19 virus, parvovirus B19 or sometimes erythrovirus B19, was the first (and until 2005 the only) known human virus in the family Parvoviridae, genus Erythroparvovirus; it measures only 23-26 nm in diameter. The name is derived from Latin, parvum meaning small, reflecting the fact that B19 ranks among the smallest DNA viruses The human parvovirus B19 causes parvovirus infection. This is different from the parvovirus seen in dogs and cats, so you can't get the infection from a pet or vice versa. Human parvovirus infection is most common among elementary school-age children during outbreaks in the winter and spring months, but anyone can become ill with it anytime of. Human parvovirus, or parvovirus B19, is a common infectious viral disease that is spread from person to person. Cases of parvovirus infection are more likely to occur in late winter to early spring. Local outbreaks of human parvovirus infection tend to be cyclical. Parvovirus affects people of all ages and ethnic groups SUMMARY Parvovirus B19 (B19) was discovered in 1974 and is the only member of the family Parvoviridae known to be pathogenic in humans. Despite the inability to propagate the virus in cell cultures, much has been learned about the pathophysiology of this virus, including the identification of the cellular receptor (P antigen), and the control of the virus by the immune system Parvovirus B19 has been linked with various clinical syndromes including neurological manifestations. However, its role in the latter remains not completely understood. Although the last 10 years witnessed a surge of case reports on B19-associated neurological aspects, the literature data remains sc

Human parvovirus B19 infections are common. They are usually mild or asymptomatic, and do not require treatment. In some cases, however, infection is associated with sufficiently severe complications that treatment is indicated and may be lifesaving.

Parvovirus B19 is a virus that causes a common childhood illness, also called fifth disease or erythema infectiosum. The virus is found in respiratory droplets during an infection and is easily transmitted to others through close physical contact Human parvovirus B19 is the only parvovirus known to be a human pathogen. The structure of recombinant B19-like particles has been determined to ≈3.5-Å resolution by x-ray crystallography and, to our knowledge, represents the first near-atomic structure of an Erythrovirus . The polypeptide fold of the major capsid protein VP2 is a jelly roll with a β-barrel motif similar to that.

Fourteen (45%) patients had underlying diseases, including six (19%) with immunologic diseases, five (16%) with hematologic diseases, and three (10%) with cardiopulmonary diseases. Only seven (23%) patients received an initial impression of erythema infectiosum prior to positive PCR
  2. Human parvovirus B19 (B19V) is a small (22-24 nm) nonenveloped DNA virus belonging to the genus Erythrovirus (family Parvoviridae). Although it generally causes self-limiting conditions in healthy people, B19V infection may have a different outcome in patients with inherited hemolytic anemias
  3. Parvovirus B19 (B19V) is a member of the family Parvoviridae, genus Erythrovirus. B19V-specific IgG and IgM react differently against conformational and linear epitopes of VP1 and VP2 antigens, leading to the development of IgG avidity and epitope type specificity (ETS) enzyme immunoassays (EIAs) for distinguishing past from recent infection
  4. Parvovirus B19 infection may cause slapped cheek syndrome (erythema infectiosum or fifth disease), commonly in school-age children. It is usually a mild, self-limiting illness. Complications of parvovirus B19 infection are rare in healthy people
  5. Parvovirus B19, the first known pathogenic human parvovirus, was discovered by chance in healthy blood donors being screened for hepatitis B. 1 The name comes from the single isolate within a panel of hepatitis sera in which the virus was discovered (panel B, serum 19)

Parvovirus B19 (B19V) is pathogenic to humans and causes bone marrow failure diseases and various other inflammatory disorders. B19V infection exhibits high tropism for human erythroid progenitor cells (EPCs) in the bone marrow and fetal liver. The exclusive restriction of B19V replication to erythroid lineage cells is partly due to the expression of receptor and co-receptor(s) on the cell.
