Rubella can be prevented by immunization. Rubella is a mild but very contagious disease that is preventable with a vaccine. Other names for rubella are German measles and three-day measles. Rubella is dangerous because of its ability to harm unborn babies. Infection of a pregnant woman can result in miscarriage, stillbirth, or serious birth defects.
Rubella is caused by the rubella virus.
Rubella is found worldwide. People get rubella by breathing in droplets that get into the air when an infected person coughs, sneezes, or talks. Rubella can also spread by direct contact with fluids from the nose or throat of an infected person. Most cases of rubella are mild. About half of people infected with rubella virus get a rash that looks like small, fine pink spots.
