Introduction and description

Parvovirus is the common name applied to all the viruses in the Parvoviridae taxonomic family. The Parvoviridae are a family of small, rugged, genetically-compact DNA viruses.  There are currently over 75 species in the family, divided among 13 genera and two subfamilies:

Subfamily Densovirinae - infects invertebrates.  To date, very few viruses from the Densovirinae have been studied and sequenced, so the taxonomy may poorly reflect the true diversity of this subfamily.  The genera are

  •  Ambidensovirus - Genus includes 11 recognized species that infect insects from multiple orders, crayfish (crustacea) or sea stars (echinoderms)
  • Brevidensovirus - Genus includes 2 recognized species that infect insects from the order Diptera
  • Hepandensovirus - Genus includes a single species, infecting decapod shrimp
  • Iteradensovirus - Genus includes 5 recognized species that infect insects from the order Lepidoptera
  • Penstyldensovirus - Genus includes a single species, infecting decapod shrimp

Subfamily: Parvovirinae  - infect vertebrates .  Currently, viruses that infect humans are recognized in 5 genera: Bocaparvovirus (human bocavirus 1–4, HboV1–4), Dependoparvovirus (adeno-associated virus 1–5, AAV1–5), Erythroparvovirus (parvovirus B19, B19V), Protoparvovirus (bufavirus 1–3, BuV1–3; cutavirus, CuV) and Tetraparvovirus (human parvovirus 4 G1–3, PARV4 G1–3).

  • Amdoparvovirus - Genus includes 4 recognized species, infecting mink, fox, racoon dogs and skunk
  • Aveparvovirus - Genus includes a single species, infecting turkeys and chickens
  • Bocaparvovirus - Genus includes 21 recognized species, infecting mammals from multiple orders, including primates
  • Chapparvovirus - Proposed additional genera include Chapparvovirus. Consideration of the taxon awaits further investigation and ultimately a decision by the ICTV
  • Copiparvovirus - Genus includes 2 recognized species, infecting pigs and cows
  • Dependoparvovirus - Genus includes 7 recognized species, infecting mammals, birds or reptiles
  • Erythroparvovirus - Genus includes 6 recognized species, infecting mammals, specifically primates, chipmunk or cows
  • Protoparvovirus - Genus includes 11 recognized species, infecting mammals from multiple orders, including canines and primates
  • Tetraparvovirus - Genus includes 6 recognized species, infecting primates, bats, pigs, cows and sheep

Canine parvovirus, for example, causes a virulent and contagious disease in dogs. In cats, a parvovirus causes feline distemper.  Because the viruses require actively dividing cells to replicate, the type of tissue infected varies with the age of the animal.

Parvoviruses are among the smallest viruses (hence the name, from Latin parvus meaning small) and are 18–28 nm in diameter.  Perhaps due to their extremely small size, parvoviruses were only recently discovered, for example:

  •  Dependoparvoviruses, the first parvoviruses to be discovered, were first isolated in the 1960s. Dependoviruses require helper viruses (e.g. herpesviruses) to replicate
  • Parvovirus B19, also known as erythroparvovirus 1, or erythrovirus B19, in the genus Erythroparvovirus, was the first known parvovirus to infect humans.  It was discovered in London by Australian virologist Yvonne Cossart in 1974. The virus is named for the patient code of one of the blood bank samples involved in the discovery.


Parvovirus particles (virions) have a durable non-enveloped protein capsid that contains a single copy of the linear single-stranded ~ 5kb DNA genome, which terminates in small imperfect palindromes that fold into dynamic hairpin telomeres. These terminal hairpins are hallmarks of the family.  They are very difficult to isolate or identify and many parvoviruses are exceptionally resistant to inactivation, remaining infectious for months or years after release into the environment.

Parvoviruses are believed to be very old, despite being discovered only relatively recently.  The most recent common ancestor of the extant strains of B19, for example, has been dated to about 12,600 years ago. Three genotypes - 1,2 and 3 - are recognised. A recombination between types 1 and 3 gave rise to genotype 2 between 5,000 and 6,800 years ago.


HboV1–4 - human bocavirus 1–4

Human bocavirus 1 [HBoV1] is an agent of acute respiratory infection frequent in children and appears to cause severe wheezing that can be mistaken for asthma. It can also cause inflammatory diseases of the middle ear, and pneumonia in infants in the absence of epidemiological risk factors and comorbidities.

Human bocavirus 1 (HBoV1) DNA is frequently detected in the upper airways of young children with respiratory symptoms. Because of its persistence and frequent co-detection with other viruses, however, its etiologic role has remained controversial. During 2009-2011, …. we examined 1,952 serum samples collected consecutively at 3- to 6-month intervals from 109 constitutionally healthy children from infancy to early adolescence. Primary HBoV1 infection, as indicated by seroconversion, appeared in 102 (94%) of 109 children at a mean age of 2.3 years; the remaining 7 children were IgG antibody positive from birth. Subsequent secondary infections or IgG antibody increases were evident in 38 children and IgG reversions in 10. Comparison of the seroconversion interval with the next sampling interval for clinical events indicated that HBoV1 primary infection, but not secondary immune response, was significantly associated with acute otitis media and respiratory illness.  PMID:  22305021

Three new members of the genus Bocavirus, human bocavirus 2 (HBoV2), human bocavirus 3 (HBoV3), and human bocavirus 4 (HBoV4), were discovered relatively recently. HBoV2-4 occur mainly in the gastrointestinal tract but rarely in the respiratory tract, research into these viruses is ongoing

A variety of signs and symptoms have been described in patients with HBoV infection including rhinitis, pharyngitis, cough, dyspnea, wheezing, pneumonia, acute otitis media, fever, nausea, vomiting, and diarrhoea. Many of these potential manifestations have not been systematically explored, and they have been questioned because of high HBoV co-infection rates in symptomatic subjects and high HBoV detection rates in asymptomatic subjects. However, evidence is mounting to show that HBoV1 is an important cause of lower respiratory tract illness. The best currently available diagnostic approaches are quantitative PCR and serology. This concise review summarizes the current clinical knowledge on HBoV species. PMID:  22038931

AAV1–5 - adeno-associated virus 1–5

Adeno-associated virus (AAV) infects humans and some other primate species. It belongs to the genus Dependoparvovirus. The virus is a small (20 nm) replication-defective, non-enveloped virus.

AAV is believed not to cause disease, but Dependoviruses require helper viruses (e.g. herpesviruses) to replicate and they may confer some more virulent properties to their symbiotic viral partners. The virus itself appears to cause a very mild immune response.  AAV vectors integrate into the host cell genome.  Despite an apparent lack of understanding of the effect of interaction between viruses, wild-type AAV has attracted considerable interest from gene therapy researchers and has even proceeded to trials.  Needless to say this has caused some concern amongst those whose research goal is in finding the cause of the diseases being targeted, simply because the cause of the disease may be the very virus helped by AAV. 

BuV1–3  - bufavirus 1–3, and cutavirus, CuV

Research into Bufavirus is very recent.  In one study in 2016, for example, results indicated that BuV infections might be widespread in Asia. The BuV-specific humoral immune responses appeared to be strong and long-lasting, pointing to systemic infection in humans.  Bufavirus was only discovered in 2012 using metagenomics testing.  One known symptom is diarrhoea.

….the BuV genotypes represent distinct serotypes. Furthermore, we analysed by BuV qPCR stool and nasal swab samples from 955 children with gastroenteritis, respiratory illness, or both, and found BuV DNA in three stools (0.3%) and for the first time in a nasal swab (0.1%).  PMID:  27966636

Cutavirus is a new human protoparvovirus related to human bufavirus and preliminarily named cutavirus.

We detected cutavirus in a sample of cutaneous malignant melanoma by using viral enrichment and high-throughput sequencing. The role of cutaviruses in cutaneous cancers remains to be investigated.  PMID:  28098541

PARV4 G1–3 - human parvovirus 4 G1–3

Parvovirus 4 (PARV4) was first discovered in 2005, in a hepatitis B virus-infected injecting drug user (IDU). To date, the best evidence about PARV4 transmission is parenteral roots which comes from IDU individuals. It seems that the prevalence of the virus in the normal population is very low. [PMID:  29910855]

Human parvovirus 4 (PARV4) has also been detected in blood and diverse tissues samples from HIV/AIDS patients who are injecting drug users, as well as HCV infected and HBV infected subjects.  No statistical difference was found in PARV4 prevalence between HBV or HCV infected subjects. [PMID:  22235298]

B19V - parvovirus B19,  [which causes Fifth disease]

B19 virus is most known for causing disease in the paediatric population; however, it can also affect adults.  Any age may be affected, although it is most common in children aged six to ten years.  

It is the classic cause of the childhood rash called fifth disease or erythema infectiosum,  The associated bright red rash of the cheeks gives it the nickname "slapped cheek syndrome".  Fifth disease, however, is only one of several expressions of Parvovirus B19.

In temperate climates the infection usually occurs in spring. The virus is spread by respiratory droplets; blood-borne transmission, however, has been reported.  Most persons with parvovirus B19 infection are asymptomatic or have mild, nonspecific, cold-like symptoms.

Infected patients with normal immune systems are contagious before becoming symptomatic. The incubation period is 4–21 days, with the average being 16 to 17 days. Symptoms last about a week.  The following symptoms are characteristic:

  • The disease commences with high fever and malaise, when the virus is most abundant in the bloodstream. There may be headache, nausea and diarrhoea.
  • As the fever breaks, a red rash forms on the cheeks, with relative pallor around the mouth ("slapped cheek rash"), sparing the nasolabial folds, forehead, and mouth.  Patients are usually no longer infectious once the characteristic rash of this disease has appeared.
  •  "Lace-like, (reticular)" red rash on trunk or extremities then follows the facial rash.. This lacy, itchy full-body rash can last up to 3 weeks.  There is exacerbation of the rash by sunlight, heat, and stress.   In adults the rash is often absent
  • Arthralgias and arthritis are commonly reported in association with parvovirus B19 infection in adults. Typically joint symptoms last 1–3 weeks, but in 10–20% of those affected, it may last weeks to months.  Arthropathy, which tends to be symmetrical and involve multiple joints, is more common among middle-aged women
  • Most patients have a decrease of erythropoiesis (production of red blood cells) during parvovirus 19 infection
  • Teenagers or young adults may develop the so-called "Papular Purpuric Gloves and Socks Syndrome".
    …We present four children with unusual exanthems associated with parvovirus infection: a purpuric periflexural pattern, a purpuric vasculitic pattern, and a combination of the two.  PMID:  30230024

The illness is self-limiting, and most healthy people recover with lasting immunity to reinfection.  Individuals with B19 IgG antibodies are generally considered immune to recurrent infection. About half of adults are B19-immune due to a past infection.

Risks during pregnancy

Parvovirus infection in pregnant women is associated with hydrops fetalis.  This is due to a combination of haemolysis of the red blood cells, as well as the virus directly negatively affecting the red blood cell precursors in the bone marrow.  Parvovirus infects the fetal liver, the main site of erythrocyte production during early development, and can induce severe anaemia and perhaps myocarditis, both of which may lead to congestive heart failure (“hydrops fetalis”).

Parvovirus can also result in miscarriage or stillbirth. There is a 5%–9% risk of fetal loss among infected pregnant women; the risk appears to be greatest in the second trimester.  The risk of transplacental infection among women who are infected during pregnancy is about 30%.

Other complications

Certain populations are vulnerable to complications from the interrupted erythropoiesis that arises with infection. These populations include people with hematologic disorders that cause an increased rate of erythrocyte destruction, such as hereditary spherocytosis and sickle cell disease

People who have a high demand for erythrocyte production are at risk of experiencing severe anaemia or a transient aplastic crisis. In addition, people who are unable to generate an adequate antibody response, such as people with HIV infection, are at risk of persistent parvovirus infection.


Not enough is known about HboV1–4, AAV1–5, BuV1–3; CuV) and PARV4 G1–3 to reliably provide more detail, however, Parvovirus B19 (B19V) has been studied for some time and many new and interesting facts are beginning to emerge about this virus that may affect our understanding of the others in this group.

The pattern of genetic evolution, its peculiar properties and functional profile, …its complex relationship with the host and its ample pathogenetic potential are all topics that are far from a comprehensive understanding.  PMID:  25283854

The role of helper viruses

Parvovirus B19 is a small non-enveloped DNA virus. It is a human pathogen that preferentially replicates in erythroid progenitor cells.  Erythroid progenitor cells are self-renewing stem cells that give rise to only one type of cell, namely, the erythrocytes (red blood cells). 

B19V is thus an autonomous parvovirus, representing a majority of the Parvoviridae family members that can replicate by themselves in host cells.  In other words B19 has no need of helper viruses to replicate.  This is in contrast to AAV that requires coinfection of a helper virus, such as adenovirus, for replication. 

But, recent research has shown that the genome of human parvovirus B19 virus can replicate in non-permissive cells with the help of adenovirus genes and produces infectious virus.  In other words it has expanded its range of infection by using a helper virus.

B19V, research has discovered, finds its way and persists in many other non-erythroid tissues.  B19V capsid RNA or proteins have been reported in bone marrow, colon, heart, liver, lymphoid, synovial, testicular, and thyroid tissues and more are being found. [PMID: 24998884]

The role of latency

Erythropoiesis is probably temporarily suppressed in all B19 infections, since in experimental settings reticulocyte counts in previously healthy seronegative volunteers have been observed to temporarily drop to zero a week or so after inoculation.  Hemoglobin levels ordinarily remain stable because the erythrocyte has a long half-life. In most people the virus is highly immunogenic, and at the time of presentation almost all patients have detectable IgM antibodies, which persist for 2 to 3 months after acute infection. Antibody production is correlated with the disappearance of the virus from the bloodstream, and IgG production appears to confer lasting immunity. Infection is global and very common. About half of 15-year-olds have specific antiparvovirus B19 antibodies. Uninfected adults remain susceptible, and most become infected and seropositive during the course of their lifetimes PMID: 15767606

So B19 is a virus capable of latency, which can establish a latent infection in numerous organs.  It occurs world-wide, kicks the immune system into life with a vengeance, and the body is able to remember the infection.  Even if one doesn’t catch this virus when young, it seems that most adults eventually catch it anyway.  The symptoms are generally relatively mild when young and may even be asymptomatic.  This virus is extremely difficult to detect - Parvovirus B19 measures only 23–26 nm in diameter and ranks among the smallest DNA viruses. 

In battle or symbiosis?

One of the other interesting and possibly important things about B19, is that it appears in some cases to act with other viruses, besides the adenovirus mentioned above.  It is almost impossible to work out whether the virus is actually in battle with the other virus and the symptoms are simply a by-product of the battle, or whether the two viruses act in concert to produce a more severe outcome.  Allies or enemies?  Or both?  In the section on the Coxsackievirus, we saw that the human body is a battleground of competing pathogens – bacteria with bacteriophages, viruses, fungi, and parasites, all using the body as a resource to stay alive.  In some cases they deliberately kill the body in order to spread to other bodies, enabling themselves to be released from their prison body.  It is relatively early days for research in this area but the signs are all there that B19 is a major pathogenic player:

An 11-year-old boy presented with epistaxis, petechial hemorrhages, easy bruising, and purpuric rash. He was diagnosed to have immune thrombocytopenic purpura and evidence of concomitant parvovirus B19 and dengue viral infection.  PMID:  22544695


Co-infection of parvovirus B19 with hepatitis B and C viruses has been found in patients with acute and chronic hepatitis,  however, the conclusion that parvovirus B19 infection increased the frequency of liver disease was not supported. PMID: 21328387

But it might have made the outcome more severe. 


B19V uses the cellular DNA replication machinery for viral DNA replication.  STAT5 in cells controls cell growth and division, or cell proliferation.  It regulates programmed cell death, or apoptosis, as well as cell differentiation and inflammation.  There appears to be some indication that B19 is able to control STAT5 in order to replicate.  This may indicate that B19 has some role in the development of cancer [PMID:  29922597].  Please note however that this is a very tentative hypothesis, based on very recent research that has not been fully explored. 

The role of Immunosuppression and immunosuppressants

You may be at risk for serious complications from B19 infection if you have a weakened immune system caused by, for example, stress - including grief, fear, depression, anxiety and so on -  or HIV infection.  Hypoxia stresses the body too and has been shown to boost productive B19V infection through enhancement of erythropoietin receptor signaling

…. a significant enhancement of B19V DNA replication as well as progeny virus production has been observed during B19V infection of hEPCs when they were cultured under 1% O2 (hypoxia) …. …. Strikingly, hypoxia regulates Epo/EpoR receptor signaling, which is essential for B19V DNA replication, and thereby, enhances B19V DNA replication.  PMID: 26097496

So people with atherosclerosis or endothelial dysfunction, smokers, those with lung disease, or those who suffer from sleep apnea [all of which result in hypoxia] may also suffer an outburst of B19 infection.

But far more dangerous appears to be the role of Immunosuppressants – sometimes simply known as ‘steroids’.  Immunosuppressants suppress the immune system and are increasingly being implicated in a large number of illnesses which are complications of simpler infections.

Immunosuppressants are often given to those with so-called Auto-immune diseases.  Under the entirely mistaken belief that the body attacks itself using its immune system, immunosuppressants are used to suppress the ‘attack’.  But the body is normally attacking pathogens - often difficult to detect because they are small or not being looked for.  Smoke particles, nanoparticles and very small viruses, for example, go undetected.

Dexamethasone is an anti-inflammatory and immunosuppressant.  Ironically it is on the World Health Organization's List of Essential Medicines. It is available in most areas of the world and is inexpensive and thus frequently prescribed and it is implicated in causing viral encephalitis complications

Human parvovirus B19 generally causes erythema infectiosum in childhood, but it can be associated with unusual findings, particularly in immunocompromised patients. This is a report about a 4-year-old female child affected with acute encephalitis by parvovirus B19, documented by polymerase chain reaction performed on cerebrospinal fluid.  She was treated with intravenous immunoglobulins and dexamethasone and developed a cerebellar syndrome with ataxia, dysmetria, and dysarthria.  PMID:  18487517

Given that illness and disease is caused by either pathogens such as viruses, bacteria, fungi or parasites; or toxins like heavy metals or pesticides, herbicides and insecticides;  radiation, and nutritional deprivation; it seems extremely unwise to suppress the immune system – giving the cause of the illness the chance to wreak more havoc completely unopposed by the body’s only defence.  Admittedly it gives the patient the impression that since the symptoms have disappeared they must be getting better, however, this is not at all helpful - they will clearly eventually become a great deal worse and may well die…. From cancer, from heart disease etc etc. 

It might be worth knowing that according to eHealthme, which collects the ADRs submitted by doctors to the FDA and SEDA, the most common side-effect for the immunosuppressant Rituxan [the trade name for rituximab ] is death.

Destruction of the Blood brain barrier

A range of toxic substances cause the destruction of the blood brain barrier – everything from aluminium, lead, cadmium, mercury and nanoparticles, to those vaccines which have an aluminium adjuvant:

Human parvovirus (HPV) B19 is a rare cause of encephalitis in children and immunocompromised adults. The authors describe a case of an otherwise healthy woman who developed encephalitis complicated by prolonged status epilepticus. Human parvovirus B19 infection was suggested by a prodromal, malar rash and established by the presence of specific IgM and IgG antibodies in the patient's serum. This is the first reported case of HPV B19 encephalitis in an immunocompetent adult. PMID: 11591864

Diagnosis, Prevention and Treatment

At the moment, there are no treatments that directly target Parvovirus B19 virus or any of the other viruses described here.


These viruses are prevalent worldwide and are culturable in vitro, and serological and molecular assays are available but require careful interpretation of results.[ PMID: 27806994]

A clinical diagnosis can be made without laboratory confirmation if erythema infectiosum is present. If laboratory confirmation is needed, serum immunoglobulin M testing is recommended for immunocompetent patients; viral DNA testing is recommended for patients in aplastic crisis and for those who are immunocompromised. Treatment is usually supportive, although some patients may require transfusions or intravenous immune globulin therapy. Most patients recover completely.  PMID:  17304869

Metagenomic testing is also possible in some countries.


There is no need to keep infected children away from school, since in most people this illness is mild and self-limiting, and most children are no longer infective by the time the rash appears and the diagnosis is made. Frequent hand washing can reduce the spread of respiratory droplets. The US Centers for Disease Control and Prevention says that it “does not recommend that pregnant women be routinely excluded from a workplace where an outbreak is occurring. The decision to stay away is a personal decision made after the woman's discussions with her family, doctor and employer”.

It is worth noting that B19 can be acquired via blood transfusion

As part of its life history it replicates to high titre in the bone marrow, and in acute infection high titres of infectious virus are present in the peripheral blood. Parvovirus B19 is therefore not an uncommon 'contaminant' of blood and blood products. In addition the lack of lipid membrane envelope renders parvoviruses insensitive to solvent detergents, and the small genome confers relative resistance to heat and gamma irradiation. PMID:  15645675


blood donations that are targeted at high-risk groups are only beginning to be screened for B19 IgG and DNA as a means of minimizing exposure of at-risk patients to the virus. PMID: 15150324


Most healthy infected people do not need to consult a physician.. There is no specific therapy, warmth, sleep, rest, adequate fluid intake, are all advised.
