Rubella virus is the sole member of the genus Rubivirus, in the family Matonaviridae. Rubella virus is a human virus belonging to the family Togaviridae and the sole member of the rubivirus genus. Contents. It usually causes an acquired, generally benign, self‐limiting postnatal infection mainly in children, producing a fever and rash. Rubella Virus. [18] For these reasons, rubella is included on the TORCH complex of perinatal infections. Rubella, also known as German measles or three-day measles,[5] is an infection caused by the rubella virus. Rubella is most commonly spread when someone ingests (swallows) or inhales the cough or sneeze droplets from an infected person. [1] Infection during early pregnancy may result in a miscarriage or a child born with congenital rubella syndrome (CRS). The Togaviridae Virus Family. Once inside the cell, budding of capsids to form virions occurs at the Golgi apparatus or the cytoplasmic membrane. • This family has two genera: • Alphaviruses : mosquito-born and infect a wide range of vertebrates. Rubella virus (RuV) is the pathogenic agent of the disease rubella, and is the main cause of congenital rubella syndrome when infection occurs during the first weeks of pregnancy.. Cerutis, in Reference Module in Biomedical Sciences, 2014. In rubella virus-infected cells, actin depolymerizes into filaments late in infection, although microtubular changes are not apparent. Horses also may be severely or fatally infected, by equine encephalitis. W.B. By continuing you agree to the use of cookies. He coined the name "rubella" (from the Latin word, meaning "little red") in 1866. In all cell lines in which RV replicates, persistent infections are readily established and maintained, whether or not the cell line exhibits a functional interferon system. Infectious virus is released into the media for several subcultures of infected cells. Persistent RV infection in cell culture cannot be cured by the inclusion of neutralizing antibodies in the culture medium because virus budding occurs at intracytoplasmic locations. Therefore, rubella virus may persist outside of the CNS, causing an adaptive immune response to the virus which in turn causes immunopathology within the CNS, ultimately resulting in PRP (Frey, 1997). The spectrum of fetal infection varies from extensive involvement of multiple organs when infection occurs early in the first trimester, to focal involvement of few organs, especially of the eye and auditory system, which occurs in fetal infections after 11 to 12 weeks of gestation. Rubella virus, since it was first identified in 1962, has been the only known member of its virus family, Matonaviridae. Rubella virus is a human virus belonging to the family Togaviridae and the sole member of the rubivirus genus. Other pathologic effects are focal inflammation, edema, and granulomatous changes. • So, Rubella has a genus all to itself, Rubivirus. [35] Since the introduction of vaccine, occurrences have become rare in those countries with high uptake rates. [49] In the years 1964–65, the United States had an estimated 12.5 million rubella cases. [1] It usually starts on the face and spreads to the rest of the body. Adult women are particularly prone to arthritis and joint pains. Although rubella virus may establish persistent, non-cytocidal infections, it can also cause cytopathic effects that are due to apoptotic cell death. an ophthalmologist in Australia in 1941, Dr. Norman Gregg, first linked the rubella virus with congenital birth defects the incubation period of rubella can range from 12 to 23 days; up to half of people with rubella don't have any symptoms or any obvious symptoms, although they can still be contagious to others Together, these findings show that some members of the family Matonaviridae can cross substantial barriers between host species and that rubella virus probably has a zoonotic origin. [37] During the epidemic in the U.S. between 1962 and 1965, rubella virus infections during pregnancy were estimated to have caused 30,000 stillbirths and 20,000 children to be born impaired or disabled as a result of CRS. RV replicates in a number of laboratory cell culture lines; however, in most of these no cytopathic effects (CPEs) are usually observed. Primary infection most often causes a benign illness, but rarely neurologic involvement occurs (Nath, 2003). discrete rash with posturicular and suboccipital lymphadenopathy Compare to ordinary measles, patients appear redder. [47][48] Gregg published an account, Congenital Cataract Following German Measles in the Mother, in 1941. Pregnant women are usually tested for immunity to rubella early on. Chen MH, Frey TK J Virol 1999;73:3386-3403. TRANSMISSION. [17] It may also cause prematurity, low birth weight, and neonatal thrombocytopenia, anemia and hepatitis. Read More; type of togavirus. Also HUVEC (primary fetal endothelial cells derived from human umbilical vein) can be used. Many of these actions have not been delineated in rubella infection, although E1 is believed to facilitate adhesion to red blood cells and initiate viral infection. It is an enveloped virus with a single-stranded RNA of positive polarity and has a single antigenic type. J.B. Hanshaw, J.A. The Togaviridae family is also comprised of the Alphavirus genus, which includes viruses, such as Sindbis virus and Semliki Forest virus. Placental and fetal infection with rubella virus occurs most consistently after maternal infection during the first trimester of pregnancy, and early fetal infection, especially during organogenesis, is associated with increasing risk of fetal death or teratogenicity.8,9 Maternal rubella infection in the first trimester of pregnancy results in fetal infection rates of 80% to 100%. The rubella virus is a typical … [38][39] [53][54], In 1967, the molecular structure of rubella was observed under electron microscopy using antigen-antibody complexes by Jennifer M. Best, June Almeida, J E Banatvala and A P Waterson. Since no vaccine was yet available, some popular magazines promoted the idea of "German measles parties" for infected children to spread the disease to other children (especially girls) to immunize them for life and protect them from later catching the disease when pregnant. Universal immunisation producing a high level of herd immunity is important in the control of epidemics of rubella. Forchheimer spots occur in 20% of cases and is characterized by small, red papules on the area of the soft palate. Introduction of this virus. H. Cody Meissner, Davidson H. Hamer, in International Encyclopedia of Public Health (Second Edition), 2017. The virus causes a disease also commonly referred to as the "German Measles". [12], In children, rubella normally causes symptoms which last two days and include:[13], In older children and adults, additional symptoms may be present, including:[13], Coryza in rubella may convert to pneumonia, either direct viral pneumonia or secondary bacterial pneumonia, and bronchitis (either viral bronchitis or secondary bacterial bronchitis). In New York alone, CRS affected 1% of all births. Literature references. Thus, rubella virus is highly adapted for persisting infection both at the cellular level and in the presence of a humoral response. It is an enveloped virus with a single-stranded RNA of positive polarity and has a single antigenic type. Rubella virus is spread by the respiratory route. Congenital heart defects and cataracts can be corrected by direct surgery. However, subclinical infection occurs in up to 50% of cases.

Factors associated with the greater susceptibility of the placenta and fetus to rubella virus during the first trimester are unknown. Rubella virus, since it was first identified in 1962, has been the only known member of its virus family, Matonaviridae.That is, until two separate teams, working in completely different parts of the world, converged on discoveries that would forever link them. Since the introduction of the measles , mumps , and rubella (MMR) vaccine , … Since the introduction of the measles , mumps , and rubella (MMR) vaccine , it is a relatively rare condition. [7] Rubella is the third disease to be eliminated from the western hemisphere with vaccination after smallpox and polio. Progressive rubella panencephalitis (PRP) is, like SSPE, a fatal disease of childhood that can develop long after both typical childhood rubella and congenital rubella syndrome (CRS) as a result of rubella virus persistence (Berg, 1977; Townsend et al., 1982; Wolinsky, 1990). Health Care Guideline: Routine Prenatal Care. RV protein E1 both binds to the receptor and induces membrane fusion. Fourteenth Edition. This section shows the database cross-references that we have for this Rfam family. RV infection increases respiratory chain complexes with marginal induction of oxidative stress (Claus et al., 2013). The new viruses also provide scientists with new tools to probe the biology of rubella virus and the Matonaviridae family. Continuous cell lines commonly used to propagate RV include Vero (African green monkey kidney), RK-13 (rabbit kidney), BHK-21 (baby hamster kidney), HaCaT cells (human keratinocytes). ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Encyclopedia of the Neurological Sciences (Second Edition), An icosahedral nucleocapsid encloses the genomic RNA of the, Principles and Practice of Pediatric Infectious Diseases (Fourth Edition), In contrast to acquired rubella infection, congenital infection results in a persistent, progressive infection. The virus tends to peak during the spring in countries with temperate climates. The new viruses also provide scientists with new tools to probe the biology of rubella virus and the Matonaviridae family. The rash causes itching and often lasts for about three days. Rubella virus (RV) is the etiologic agent of rubella, a mild exanthematous disease associated with low-grade fever, lymphadenopathy, and a short-lived morbilliform rash.Rubella was first described as a distinct disease in the early 1800s. [11], Rubella can affect anyone of any age. Typically, the virus first replicates in the upper respiratory tract and in the nasopharyngeal lymphoid tissue, spreading from there to regional lymph nodes (Cooper and Buimovici-Klein, 1985), (Wolinsky et al., 1996). Rubella virus 5 6. About 100,000 cases of this condition occur each year.[3]. D.R. By 16 weeks of gestation, the fetal infection rate drops to 10% to 20%, but it rises again to 60% or higher after 30 weeks of gestation.10,11. All these physicians were German, and the disease was known as Rötheln (contemporary German Röteln), Rötlich means "redish" or "pink" in German. [57][58] On April 29, 2015, the Americas became the first WHO region to officially eradicate the disease. The overexpression of p32 in cell lines enhances rubella virus infectivity (Mohan et al, 2002). [51] In 1938, Hiro and Tosaka confirmed this by passing the disease to children using filtered nasal washings from acute cases. Rustrela virus, which is an outgroup to the clade that comprises rubella and ruhugu viruses, was found in acutely encephalitic placental and marsupial animals at a zoo in Germany and in wild yellow-necked field mice (Apodemus flavicollis) at and near the zoo. Mutagenic analysis of the 3' cis-acting elements of the rubella virus genome. The name rubella is derived from a Latin term meaning "little red." For other uses, see. Togaviruses are single-strand RNA viruses surrounded by an icosahedral capsid, which is a spherical protein shell made up of 20 equilateral triangular faces, all within a spherical outer lipid envelope . Rubella virus is an enveloped positive-strand RNA virus of the family Togaviridae. Taxonomy; Creation of New Matonaviridae Family; Transmission; Morphology; Phylogeny; Structure; Genome; Replication; Capsid protein; Epidemiology The rash is sometimes itchy and is not as bright as … [16], Rubella can cause congenital rubella syndrome in the newborn, this being the most severe sequela of rubella. Rubella is still common in some regions of the world and Susan E. Reef, team lead for rubella at the C.D.C.’s global immunization division, who joined in the announcement, said there was no chance it would be eradicated worldwide before 2020. A variety of experimental animals can be infected with rubella virus although there are no reliable animal models of symptomatic rubella infection in humans or for congenital rubella syndrome. Additionally, the virus persists in spite of the interferon response it induces in most of these cell lines. [3] Once infected there is no specific treatment. [3] Diagnosis is confirmed by finding the virus in the blood, throat, or urine. Continuous cell lines routinely used to propagate rubella virus include Vero (AGMK), RK-13 (rabbit kidney), and BHK-21 (baby hamster kidney). [47][49], There was a pandemic of rubella between 1962 and 1965, starting in Europe and spreading to the United States. Scientists had never identified close relatives of the virus, leaving it as the only member of its genus, Rubivirus.But with a report in this week's issue of Nature, rubella has gained a family.One of its two newfound relatives infects bats in Uganda; the other killed animals from three different species in a … Copyright © 2021 Elsevier B.V. or its licensors or contributors. However, the primary symptom of rubella virus infection is the appearance of a rash (exanthem) on the face which spreads to the trunk and limbs and usually fades after three days, which is why it is often referred to as three-day measles. The virus is found in the blood 5 to 7 days after infection and spreads throughout the body. The Rubella virus is part of the Togaviridae family. Rubella (measles rubella) is an acute infectious disease characterized by spotty rashes on the skin, catarrh of the upper respiratory tract and conjunctiva, an increase in the cervical lymph nodes and signs of minor general intoxication.. • Rubivirus • Only Togavirus that is not arbovirus. The infection is usually mild with fever and a rash. Rubella virus (RV), the sole member of the genus Rubivirus within the family Togaviridae, is a small enveloped, positive strand RNA virus. Rubella virus, rubivirus from the Togaviridae family). [44][47][48][49], It was formally recognised as an individual entity in 1881, at the International Congress of Medicine in London. Sequencing of the ∼10 000 nucleotide long, single-stranded rubella genome has been completed. [1] When some, but less than 80%, of a population is vaccinated, more women may reach childbearing age without developing immunity by infection or vaccination, thus possibly raising CRS rates. Rubella virus is another example where there is a long history of safe and effective vaccination with a live-attenuated vaccine indicating that it may hold promise as an efficient and potent vector. No reliable animal model exists for the study of RV pathogenesis. [62][63], This article is about the disease. Rubella virus 5 6. Pan-American Health Organization director remarked "The fight against rubella has taken more than 15 years, but it has paid off with what I believe will be one of the most important pan-American public health achievements of the 21st Century. Get premium, high resolution news photos at … 143 Prior to acquiring its more common name, the disease was named Rõtheln by the German physician de Bergen, 65 leading to the common … It has been reported that nonhuman primates and a variety of laboratory animals can be infected with rubella virus, however the extent of viral replication is inconsistent among these reports and no reliable animal model exists for the study of rubella virus pathogenesis. Demyelination is a characteristic of PRP and may be mediated by the antibody arm of the adaptive immune response as oligoclonal IgG antibody bands, with specificities restricted to the structural proteins of rubella virus, are a characteristic of PRP and there has been shown to be molecular mimicry between the structural proteins of rubella virus and the proteolipid protein of myelin (Townsend et al., 1982; Wolinsky et al., 1982; Wolinsky, 1990). RUBV-induced birth defects, known collectively as congenital rubella syndrome (CRS), are due to direct infection of the fetus and can involve several organ systems, including the eyes, ears, heart, brain, and endocrine system. Get premium, high … [3][4] People are infectious during the week before and after the appearance of the rash. However, a 2007 outbreak in Argentina, Brazil, and Chile pushed the cases to 13,000 that year. Rash beginning on the face which spreads to the rest of the body. [1] Once recovered, people are immune to future infections. Morphological and biochemical changes in the mitochondria occur early in infection. Two virus-specific glycoproteins, E1 and E2, protrude as spikes from the virion envelope. The virus is transmitted by the respiratory route and replicates in the nasopharynx and lymph nodes. This interference assay is the classical standard assay for detection of rubella virus, however currently used detection assays generally employ immunofluorescence or polymerase chain reaction for detection of the virus. Live, attenuated rubella vaccines have been in use in developed countries for over 30 years with excellent results and are now being applied in elimination programs in some developing regions of the world. [48], In 1940, there was a widespread epidemic of rubella in Australia. Rubella is caused by a virus from the genus Rubivirus. The pathogenesis of CRS is not understood and CRS patients are persistently infected with RUBV at birth and can suffer progressive sequelae in addition to those apparent at birth. [55][56], In 1969, a live attenuated virus vaccine was licensed. Rubella is generally a benign communicable exanthematous disease. In togavirus …is carried by mosquitoes, and Rubivirus, which contains rubella, or German measles, virus. German physician and chemist, Friedrich Hoffmann, made the first clinical description of rubella in 1740,[44] which was confirmed by de Bergen in 1752 and Orlow in 1758. Rubella is caused by the Rubella virus, which is the only virus in the Rubivirus genus and belongs to the family of Togaviridae. Cellular p32, the C1q-binding protein, interacts with rubella virus capsid N-terminal domain. [3] Problems are rare after the 20th week of pregnancy. Rubella virus (RUBV) is a significant human pathogen that can cause a benign systemic rash illness as a result of acute infection, but severe birth defects if acute maternal infection occurs during the first trimester of pregnancy. RuV is a small, enveloped virus belonging to genus Rubivius, which has been moved in 2019 from the Togaviridae family to the newly created Matonaviridae family. [2] Each year about 100,000 cases of congenital rubella syndrome occur. If the fetus survives the infection, it can be born with severe heart disorders (patent ductus arteriosus being the most common), blindness, deafness, or other life-threatening organ disorders. When the rash clears up, the skin might shed in very small flakes where the rash covered it. The WHO recommends the first dose be given at 12 to 18 months of age with a second dose at 36 months. [1] A fever, sore throat, and fatigue may also occur. Introduction. Rubella virus (Chapter 28), of the family Togaviridae, is an enveloped single-stranded positive-sense RNA virus (Frey, 1997; Nath, 2003). Viral spike proteins engineer the steps leading to adhesion, fusion, and penetration into cells. It had not been found in animals. Classification of the Rubella virus • Belongs to the family “Togaviridae”. The Togaviridae family is also comprised of the Alphavirus genus, which includes viruses, such as Sindbis virus and Semliki Forest virus. [7], On January 22, 2014, the World Health Organization (WHO) and the Pan American Health Organization declared and certified Colombia free of rubella and became the first Latin American country to eliminate the disease within its borders. During this incu… Rubella virus (Chapter 28), of the family Togaviridae, is an enveloped single-stranded positive-sense RNA virus (Frey, 1997; Nath, 2003). Contents. Robert Kliegman, Waldo E. Nelson, Hal B. Jenson, Karen J. Marcdante, M.D., Richard E. Behrman. However their use in prepubertal females did not produce a significant fall in the overall incidence rate of CRS in the UK. A rash due to rubella on a child's back. Before the vaccine against rubella was introduced in 1969, widespread outbreaks usually occurred every 6–9 years in the United States and 3–5 years in Europe, mostly affecting children in the 5-9 year old age group. Teryl K. Frey, Jerry S. Wolinsky, in Encyclopedia of Virology (Second Edition), 1999. Some of the possible causes of Rubella or similar disorders may include: 2. In mammalian culture cell lines, persistent infections are readily established because the replication of the rubella virus does not damage the macromolecular synthesis within the cell. Its symptoms include low-grade fever, respiratory problems, and most notably a rash of pink or light red spots that typically begins on the face and spreads downward. Two live attenuated virus vaccines, RA 27/3 and Cendehill strains, were effective in the prevention of adult disease. "[59] The declaration was made after 165 million health records and genetically confirming that all recent cases were caused by known imported strains of the virus. Rubella, also known as German measles or three-day measles, is an infection caused by the rubella virus. [1][2] Joint pain is common in adults. Rubella is caused by RNA virus and has a peak age of 15 years the incubation period is 14-21 days. Jane E. Libbey, Robert S. Fujinami, in Handbook of Clinical Neurology, 2014. Rubella, also known as German measles, is a contagious disease caused by an airborne virus that has been known to be the only member of its virus family. Outbreaks still arise, usually in developing countries where the vaccine is not as accessible. [26], The immunisation program has been quite successful. The nucleocapsid consists of 40S genomic RNA and a single species of capsid protein which is enveloped within a host-derived lipid bilayer containing two viral glycoproteins, E1 (58 kDa) and E2 (42-46 kDa). Measles is caused by the Morbillivirus from the virus family Paramyxoviridae.Rubella is often called "German measles." Mice are common model species in the laboratory. Cuba declared the disease eliminated in the 1990s, and in 2004 the Centers for Disease Control and Prevention announced that both the congenital and acquired forms of rubella had been eliminated from the United States. Increased susceptibility to infection might be inherited as there is some indication that HLA-A1 or factors surrounding A1 on extended haplotypes are involved in virus infection or non-resolution of the disease. Person-to-person contact or droplets shed from the respiratory secretions of infected people. The only Togavirus that is not transmitted by an arthropod vector is _____ and it is the only _____ virus in this family Rubivirus rubella; respiratory The only species of the Rubivirus genus Rubella virus infection may be associated with inhibition of the development of organ precursor cells. Rubella virus, rubivirus from the Togaviridae family). People may shed virus from 7 days before the onset of the rash to approximately 5–7 days after rash onset. [2], Rubella is a common infection in many areas of the world. Several cellular proteins interact with either the Rubella virus genome or its proteins. Women found to be susceptible are not vaccinated until after the baby is born because the vaccine contains live virus. In all cell lines in which rubella virus replicates, persistent infections are readily established and maintained. An icosahedral nucleocapsid encloses the genomic RNA of the rubella virus. Rubella virus (RuV) is the pathogenic agent of the disease rubella, and is the main cause of congenital rubella syndrome when infection occurs during the first weeks of pregnancy. The prognosis in children born with CRS is poor.[34]. [1], Rubella has symptoms similar to those of flu. Nearly one half of individuals infected with this virus … This is a simple, plus-strand RNA virus that replicates in the cytoplasm of the infected cell. CRS refers to any combination of defects known to result from rubella virus infection during gestation and panencephalitis is one of several late-onset manifestations of CRS (Webster, 1998). [1] Babies with CRS may spread the virus for more than a year. Rubella virus can be grown in several common laboratory cell lines. Mice are common model species in the laboratory. Of these, 2,100 died as neonates, 12,000 were deaf, 3,580 were blind, and 1,800 were intellectually disabled. RUBELLA Genus: Rubivirus Family: Togaviridae It causes: German Measles German measles – a mild febrile illness accompanied by an erythematous. The fact that three Germans described it led to the common name of "German measles. An interference with actin assembly may contribute to teratogenesis (Lee and Bowden, 2000).
