toc =**Rubella Virus (German Measles) **=

History
Rubella was named by German physician [|Daniel Sennert]. It was studied in Germany near the end of the 19th century, but wasn't isolated until 1962, when a vaccine was developed. It never became an epidemic.

Symptoms
Those infected with Rubella suffer from [|short-term ailments], including respiratory problems, rashes, skin lesions, lymphadenopathy, and stiff joints. Sick fetuses are prone to more lasting disorders such as cataracts, deafness, and heart disease.

Spread
The virus is transferred from person to person through the respiratory route. It is specific to human beings.

Chemical Structure
Rubella is a spherical, [|single stranded RNA virus]. Its surface proteins contain hemagglutinin, and its core is surrounded by a lipoprotein envelope. It self-replicates inside cells of the respiratory system, then spreads throughout the body to target organs. Lymphocyte white blood cells attack cells infected with virus.

Chemical History
Rubella appears to be descended from three separate viruses.

Treatment
While there are vaccines against Rubella, there is no treatment for it. Those infected usually recover after three days.
