Dermatologic Manifestations of Rubella

Background
Rubella is usually a mild viral illness involving the skin, the lymph nodes, and, less commonly, the joints. The most important complication of rubella is congenital rubella syndrome (CRS).
Pathophysiology
Rubella is an RNA virus classified as a Rubivirus in the Togaviridae family.
Epidemiology
Frequency
United States
Before the live rubella vaccine, epidemics of the disease were seen in young children (most common), adolescents, and young adults every 5-9 years in winter and early spring. Since the rubella vaccine, the number of rubella cases has decreased significantly.
Because of the morbidity of measles and rubella, the World Health Organization (WHO) maintains a worldwide Measles and Rubella Laboratory Network (LabNet) to monitor the behavior of the viruses.[1] Because of the unreliability of clinical diagnosis, laboratory surveillance is important in setting rubella elimination goals. Serum-based diagnostics remain the criterion standard; however, programs are being developed using dried blood samples and oral fluid for confirmation of infection in those areas where patients might resist venipuncture or where transportation and refrigeration of blood samples is difficult.
One major focus of infection is now unvaccinated adults.[2] Of increasing concern is the high incidence of rubella in unvaccinated Hispanic immigrants and congenital rubella syndrome in their offspring.[3] Individuals from Columbia, the Dominican Republic, and Central America, where vaccination programs are just starting, are often susceptible to rubella. In one study, 44% of congenital rubella syndrome cases were in Hispanic infants.[4] This is a public health concern. In a recent outbreak in New York State, the infections spread from the Hispanic community, along train and work lines, to involve 14 towns and 95 individuals.
Mortality/Morbidity
Rubella is usually mild. Rarely, encephalitis, thrombocytopenia, or neuritis may occur. Such manifestations are usually self-limited.
Race
Rubella has no racial predilection.
Sex
Both sexes are equally affected by rubella.
Age
Rubella primarily affects young children, but adolescents and young adults are also affected.
