Rubella virus (Latin, rubella = little red), also known as "German Measles" (due to early citation in German medical literature), infection during pregnancy can cause congenital rubella syndrome (CRS) with serious malformations of the developing fetus. The type and degree of abnormality relates to the time of maternal infection.
Rubella peaked in 1964 and 1965, when 12.5 million cases were reported (USA). As a result, 20,000 babies were born with birth defects, 6,200 babies were stillborn, and an estimated 5,000 births were aborted, both naturally and assisted. At that time no treatment by vaccination existed and this only became available in 1969. The disease was dangerous because in children it was almost unnoticable and pregnant women often did not know that they had been exposed. Initial vaccination strategies varied between countries, in the United States infants were first to be vaccinated, while in the United Kingdom adolescent girls were first to be vaccinated.
Pregnancy effects of measles results in a higher risk of premature labor, spontaneous abortion, low-birth-weight, and possibly rare cases of birth defects with no definable pattern of malformation.
Children infected with rubella before birth (a condition known as congenital rubella) are at risk for the following: growth retardation; malformations of the heart, eyes, or brain; deafness; and liver, spleen, and bone marrow problems.
The complete genomic sequence of Rubella is now known. Rubella is a 9755 bp single stranded RNA positive-strand virus with no DNA stage (Togaviridae; Rubivirus) encoding nonstructural protein, capsid protein, glycoproteins E1 and E2. (More? Rubella Genome)

- ssRNA; linear; Length: 15,894 nt Measles virus, complete genome
- virus replication involves a viral RNA-dependent RNA polymerase (vRdRp), using as a template a nucleocapsid (NC) made of a single strand of RNA in tight complex with the nucleoprotein (N).
- negative-strand genome contains six transcription units encoding the N, phospho (P), matrix (M), fusion (F), hemagglutinin (H), and large (L) or polymerase protein.
- each N protein binds to 6 nucleotides.
- the N polymer entirely covers the 15,894-nucleotide genome.
- 23 known measles genotypes.
Model of cell virus RNA accumulation
The following 5 -step model has been described for cell virus accumulation following hours post-infection (hpi)
- 0 to ~5 hpi - incoming viral RNA-dependent RNA polymerase (vRdRp) initiated primary transcription from every gene with no detectable lag phase.
- ~5 to ~12 hpi - mRNA accumulates exponentially.
- ~12 to ~24 hpi - mRNAs, genomes, and antigenomes accumulate exponentially because of the increase of both newly available template and vRdRp.
- ~24 to ~30 hpi - genomes and antigenomes continue to accumulate exponentially at the same rate, whereas the accumulation of the transcripts slows down.
- 30+ hpi - genome and antigenome accumulation slows down, and the cell content in viral transcripts tends to decrease.
Japan - first introduced to Japan in 1966 and adopted in the national regular immunization program from 1978.
WHO Rubella Information
- Causative agent - Virus
- Reservoir - Humans
- Spread - Close respiratory contact and aerosolized droplets
- Transmission period - A few days before to seven days after rash; up to one year of age in congenitally infected
- Subclinical infection - Common
- Duration of natural immunity - Lifelong
- Risk factors for infection (for unvaccinated individuals) - Highly transmissible; crowding; low socioeconomic status
- Case-fatality rate - Less than 0.1 percent (dependent on care)
- Vaccine (number of doses); route - Rubella (one or two); subcutaneous
- Vaccine efficacy - 95 percent (at 12 months and up)
- Duration of immunity after primary series - Lifelong in most; presumed rare cases of waning immunity after one dose, not two
- Schedule - First dose at 12 to 15 months; when given, a second dose with measles vaccine
- Status as of the end of 2001 - 110 countries in 2003

The World Health Organization recommends that the combination measles-rubella or measles-mumps-rubella vaccines be introduced only after careful evaluation of public health priorities within each country and following the establishment of an adequate program for measles control as demonstrated by high coverage rates as part of a well-functioning childhood immunization program.

Norman Gregg (1892-1966) was a Sydney ophthalmologist who in 1941 identified the link between maternal rubella infection and developmental abnormalities (atypical congenital cataracts, congenital heart defects, infants small-for-gestational age) initially in his own practice. This had coincided with a rubella epidemic that occurred between 1940 to 1941.

United States Elimination of rubella and congenital rubella syndrome, 1969-2004
- 1969 - First official recommendations are published for the use of rubella vaccine. Vaccination is recommended for children aged 1 year to puberty.
- 1978 - Recommendations for vaccination are expanded to include adolescents and certain adults, particularly females.
- 1981 - Recommendations place increased emphasis on vaccination of susceptible persons in training and educational settings.
- 1984 - Recommendations are published for vaccination of workers in daycare centres, schools, colleges, companies, government offices, and industrial sites. Providers encouraged to conduct prenatal testing and postpartum vaccination of susceptible women. Recommendations for vaccination are expanded to include susceptible persons who travel abroad.
- 1990 - Recommendations include implementation of a new 2-dose schedule for measles-mumps-rubella vaccine.
Rubella and measles elimination in the Americas
In 2014 a Philippines measles outbreak of over 50,000 cases occurred. Travellers to and from the Philippines during this period led to an increase in cases occurring in other countries. For example, the USA experienced the highest number of measles cases CDC had reported in 20 years, over 600, many of the people who got measles last year were linked to travelers who had gotten measles from the Philippines.
From January 1 to January 28, 2015, 84 people from 14 states were reported to have measles. Most of these cases are part of a large, ongoing outbreak linked to an amusement park in California. On January 23, 2015, CDC issued a Health Advisory to notify public health departments and healthcare facilities about this multi-state outbreak and to provide guidance for healthcare providers nationwide.
