Rubella appears in the form of a rash. It generally shows up on the face initially and then advances to the rest of the body. The rash appears in the form of redness below the skin. The rash may also be accompanied by swollen glands; prominently in head and neck. It is a fine red rash that resembles sun burn but does not involve peeling of the skin. The rash leaves or subsides in three days and hence Rubella is sometimes called three day measles. Other visible symptoms include swelling of the joints. Rubella also results in fever and joint pain. Rubella is also known as German measles, epidemic roseola or liberty measles. It is caused by the Rubella virus that affects the respiratory tract, especially the nose and the throat.
