Rubella Virus (RUV)


The rubella virus causes a mild, self-limiting viral illness (RUV). The common name "German measles" comes from the fact that it was first described as a distinct disease in German medical literature in the early 1800s. RUV typically causes mild measles-like symptoms in children and adults. When a pregnant woman becomes infected with the virus, it can result in a serious birth defect known as congenital rubella syndrome (CRS). People who breathe in virus-infected fluid spread it. Rubella is preventable with the rubella vaccine, which is more than 95% effective with a single dose. Despite the introduction of an effective vaccine and global vaccination programs, it is estimated that approximately 110,000 CRS cases occur globally each year.

Viral Genome and Proteins

Rubella virus (RV) is a positive-polarity enveloped single-stranded RNA virus that is the only member of the genus Rubivirus within the family Togaviridae. The viral genome is approximately 10 kb in size. The virus particles range in size from 40 to 80 nanometers and have spiky hemagglutinin-containing surface projections. The virion is made up of a spherical core that contains a capsid protein and a single copy of the RNA genome. Two nonstructural proteins (P90 and P150) and three structural proteins are encoded by the genome (one nucleocapsid and two envelope glycoproteins, E1 and E2).

  • P150 and P90 are produced proteolytically from a P200 precursor. These proteins are thought to have a variety of enzymatic activities. p90 and p150 are viral replication proteins that are not immunogenic.
  • The capsid protein initially interacts with viral genomic RNA to promote viral RNA synthesis.
  • On the virion surface, the glycoproteins E1 and E2 form viral spike complexes. Because of its receptor-binding and membrane-fusion functions, E1 is the most important player during entry into target cells. It is the primary antigen and the sole target of RUV neutralizing antibodies. E1 and E2 are both capable of mediating infectious viral entry. It has previously been demonstrated that the E2 signal peptide serves as a membrane anchor for the capsid protein.
