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.[1]


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.[2] 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)

Some Recent Findings

  • Americas region is declared the world’s first to eliminate rubella 29 April 2015 (PAHO/WHO) "The Americas region has become the first in the world to be declared free of endemic transmission of rubella, a contagious viral disease that can cause multiple birth defects as well as fetal death when contracted by women during pregnancy. Before mass-scale rubella vaccination, an estimated 16,000 to more than 20,000 children were born with CRS each year in Latin America and the Caribbean, while more than 158,000 rubella cases were reported in 1997 alone. In the United States, 20,000 infants were born with CRS during the last major rubella outbreak (1964-65)." PAHO
  • Rubella[3] "Rubella remains an important pathogen worldwide, with roughly 100 000 cases of congenital rubella syndrome estimated to occur every year. Rubella-containing vaccine is highly effective and safe and, as a result, endemic rubella transmission has been interrupted in the Americas since 2009. Incomplete rubella vaccination programmes result in continued disease transmission, as evidenced by recent large outbreaks in Japan and elsewhere. In this Seminar, we provide present results regarding rubella control, elimination, and eradication policies, and a brief review of new laboratory diagnostics. Additionally, we provide novel information about rubella-containing vaccine immunogenetics and review the emerging evidence of interindividual variability in humoral and cell-mediated innate and adaptive immune responses to rubella-containing vaccine and their association with haplotypes and single-nucleotide polymorphisms across the human genome."
  • Rubella and congenital rubella syndrome control and elimination - global progress, 2000-2012[4] "Rubella virus usually causes a mild fever and rash in children and adults. However, infection during pregnancy, especially during the first trimester, can result in miscarriage, stillbirth, or infants with congenital malformations, known as congenital rubella syndrome (CRS). In 2011, the World Health Organization (WHO) updated guidance on the preferred strategy for introduction of rubella-containing vaccine (RCV) into national routine immunization schedules with an initial wide-age-range vaccination campaign that includes children aged 9 months-15 years. WHO also urged all member states to take the opportunity offered by accelerated measles control and elimination activities as a platform to introduce RCVs. The Global Measles and Rubella Strategic Plan (2012-2020) published by the Measles Rubella Initiative partners in 2012 and the Global Vaccine Action Plan endorsed by the World Health Assembly in 2012 include milestones to eliminate rubella and CRS in two WHO regions by 2015, and eliminate rubella in five WHO regions by 2020. This report summarizes the global progress of rubella and CRS control and elimination during 2000-2012. As of December 2012, a total of 132 (68%) WHO member states had introduced RCV, a 33% increase from 99 member states in 2000. A total of 94,030 rubella cases were reported to WHO in 2012 from 174 member states, an 86% decrease from the 670,894 cases reported in 2000 from 102 member states."
  • Results of the rubella elimination program in Catalonia (Spain), 2002-2011[5] "Rubella is usually a mild disease with nonspecific symptoms, but can cause congenital rubella syndrome (CRS) when infection occurs during pregnancy. The objective of this study was to evaluate the sensitivity and positive predictive value of different data sources used for surveillance purposes in the Rubella Elimination Program of Catalonia between 2002 and 2011. The Urgent Notification to the Statutory Disease Reporting System, the Individualized Disease Reporting System, screening for other viruses included in the Measles Elimination Program, the Microbiological Reporting System and the Minimum Hospital Discharge Data were evaluated. 100 suspected cases of postnatal rubella and 6 suspected cases of CRS were detected. ... Most confirmed postnatal cases (25 cases, 48.1%) were in the 25-44 y age group followed by the 15-24 y age group (11 cases, 21.2%)."
  • Controlling rubella and preventing congenital rubella syndrome – global progress, 2009 [6] "In 2009, a total of 121,344 rubella cases were reported to WHO from 167 countries, a 82% decrease from 2000"
  • An update on cardiovascular malformations in congenital rubella syndrome (CRS) [7] "We searched the English literature from 1941 through 2008 to identify studies that used cardiac catheterization or echocardiography to evaluate the cardiovascular malformations in CRS. Although published studies of CVMs in CRS have in general reported patent ductus arteriosus (PDA) as the CVM phenotype most commonly associated with CRS, among CRS cases evaluated by catheterization, branch pulmonary artery stenosis was actually more common than PDA. Moreover, although the combination of branch pulmonary artery stenosis and PDA was more common than either branch pulmonary artery stenosis or PDA alone, isolated branch pulmonary artery stenosis was twice as common as isolated PDA. ...Among children with suspected CRS, clinical evaluations for the presence of cardiovascular malformations should include examinations for both branch pulmonary artery stenosis and PDA."

Model of cell virus RNA accumulation

The following 5 -step model has been described for cell virus accumulation following hours post-infection (hpi)[9]

  1. 0 to ~5 hpi - incoming viral RNA-dependent RNA polymerase (vRdRp) initiated primary transcription from every gene with no detectable lag phase.
  2. ~5 to ~12 hpi - mRNA accumulates exponentially.
  3. ~12 to ~24 hpi - mRNAs, genomes, and antigenomes accumulate exponentially because of the increase of both newly available template and vRdRp.
  4. ~24 to ~30 hpi - genomes and antigenomes continue to accumulate exponentially at the same rate, whereas the accumulation of the transcripts slows down.
  5. 30+ hpi - genome and antigenome accumulation slows down, and the cell content in viral transcripts tends to decrease.

Rubella History

Norman Gregg (1892-1966)

1941

Norman Gregg (1892-1966) was a Sydney ophthalmologist who in 1941[10] 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.

1962

The rubella virus was initially isolated [11][12][13]

1969

United States first licensed live, attenuated rubella vaccines introduced.

  1. 1969 - First official recommendations are published for the use of rubella vaccine. Vaccination is recommended for children aged 1 year to puberty.
  2. 1978 - Recommendations for vaccination are expanded to include adolescents and certain adults, particularly females.
  3. 1981 - Recommendations place increased emphasis on vaccination of susceptible persons in training and educational settings.
  4. 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.
  5. 1990 - Recommendations include implementation of a new 2-dose schedule for measles-mumps-rubella vaccine.

2014

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.
