  Parvovirus B19 - Wikipedia, the free encyclopedia
Parvovirus B19 (B19 virus) was the first (and, until 2005, only) human parvovirus to be discovered, by chance in 1975 by the Australian virologist Yvonne Cossart.
Possibly up to 15% of all new cases of arthritis are due to parvovirus, and a history of recent contact with a patient and positive serology generally confirms the diagnosis.
Parvovirus infection in pregnant women is associated with hydrops fetalis due to severe fetal anemia, sometimes leading to miscarriage or stillbirth.

 Fifth Disease
A human virus, parvovirus B19 is not the same parvovirus that veterinarians may be concerned about in pets, especially dogs, and it cannot be passed from humans to animals or vice versa.
A person with parvovirus infection is most contagious before the rash appears - either during the incubation period (the time between infection and the onset of symptoms) or during the time when he or she has only mild respiratory symptoms.
Parvovirus B19 spreads easily from person to person in fluids from the nose, mouth, and throat of someone with the infection, especially through large droplets from coughs and sneezes.

 Parvovirus B19 May Cause Hepatitis In Kids
Parvovirus B19 DNA has been found in the blood of some patients with unexplained hepatitis, and appears to be associated with cases of fulminant hepatitis in people with failing immune systems, according to Dr. Etienne Marc Sokal, of Cliniques Universitaires St. Luc in Brussels, Belgium, and colleagues.
Investigating the potential link between parvovirus B19 and fulminant hepatitis in children, Sokal and colleagues studied 45 children hospitalized with the disease, and 82 children hospitalized with bile duct defects that also cause jaundice and liver damage.
In light of their findings, however, parvovirus B19 "should be thought of as a possible cause" of fulminant hepatitis in young children.

 Parvovirus B19 and Pregnancy
Parvovirus B19, discovered in 1975, causes a usually benign, self-limited illness, erythema infectiosum, commonly known as fifth disease.
The risk of fetal death attributable to acute parvovirus B19 infection during pregnancy is estimated to be less than 10%, ranging from 3 to 38% in different studies.
When parvovirus B19 is circulating in a community, pregnant women working in schools, day cares, and health care and other facilities with a high likelihood of exposure should be informed of the potential effects of this infection on the pregnancy; serologic testing of exposed pregnant women should be considered to determine immune status.

 Current Trends Risks Associated with Human Parvovirus B19 Infection
EI is a mild childhood illness characterized by a facial rash ("slapped cheek" appearance), and a reticulated or lacelike rash on the trunk and extremities (18).
B19 is the primary etiologic agent causing TAC in patients with chronic hemolytic anemias (e.g., sickle cell disease, hemoglobin SC disease, hereditary spherocytosis, alpha-thalassemia, and autoimmune hemolytic anemia) (22,23).
B19 antibody may not be detectable in immunodeficient patients with chronic B19 infection, and additional testing for B19 DNA or viral antigens may be necessary to document infection.

 Parvovirus B19 Abstracts & Publications : ViraCor Laboratories
Renal transplant patients were screened for the presence of parvovirus B19, before transplantation and monthly for 4 months after transplantation, by means of a sensitive nested PCR assay.
Overall, the rate of active parvovirus B19 infection in transplant subjects was low (1.42%), probably due to the high number of actively or passively immunized subjects among transplant recipients; this may also account for the asymptomatic infections observed.
We conclude that B19 parvovirus infection is probably an underestimated disease in transplant patients.

 The Facts about Fifth Disease and Parvovirus B19
A person infected with parvovirus B19 is contagious during the early part of the illness, before the rash appears.
Parvovirus B19 has been found in the respiratory secretions (e.g., saliva, sputum, or nasal mucus) of infected persons before the onset of rash, when they appear to "just have a cold." The virus is probably spread from person to person by direct contact with those secretions, such as sharing drinking cups or utensils.
Parvovirus B19 infection may cause a serious illness in persons with sickle-cell disease or similar types of chronic anemia.

Background: Parvovirus B19 (B19V), the only member of the Parvoviridae family known to cause disease in humans, is a single-strand DNA virus.
As a result of the high seroprevalence of IgG against parvovirus among adults in the general population who have recovered from infection, the antiparvovirus IgG titer in IVIG is probably sufficient to provide passive immunity for the clearance of virus in immunocompromised hosts with chronic B19V infection.

 Screening Process Reduces Risk Of Human Parvovirus B19 Transmission   (Site not responding. Last check: 2007-10-14)
In some healthy people, parvovirus B19 infection causes Fifth Disease, named so because it was the fifth disease doctors discovered that caused a red rash in children.
Because this study showed that parvovirus was in greater amounts than expected and that, in high concentrations, it could be transmitted, VITEX pursued a way to amend the normal processing of plasma to prevent the transmission of parvovirus.
The small amount of residual parvovirus does not result in transmission and would not present a risk even to patients who might be susceptible to the more serious consequences of parvovirus infection," Dr. Davenport says.
