Rubella is a contagious illness caused by a virus.
The symptoms are similar to measles and scarlet fever, but do not last as long. Rubella can cause serious problems to an unborn baby. If you are pregnant, and suspect that you have or that you have been exposed to rubella, contact your healthcare professional, immediately. Rubella is spread through indirect or direct contact with an infected person's nose or throat drainage. It can be spread when an infected person coughs or sneezes.
