The rash is gone in 3 to 4 days. There is no cure for rubella, but acetaminophen will help relieve fever and aches. Keep your child at home and away from pregnant women. Put calamine lotion on the skin to help itching. Give acetaminophen for fever.
Rubella can cause birth defects in unborn babies.
If your child has been in contact with a pregnant woman, be sure to warn her so that she can tell her doctor. Have the child rest as much as possible until the fever is gone. This usually takes about 4 days. He or she does not need to stay in bed. The child may return to school or daycare when the fever has been gone for 12 hours.
