The rubella rash usually lasts 3 days. Lymph nodes may remain swollen for a week or more, and joint pain can last for more than 2 weeks. Children who have rubella usually recover within 1 week, but adults may take longer.
Treatment
Rubella cannot be treated with antibiotics because they do not work against viral infections. Unless there are complications, rubella will resolve on its own.
Any pregnant woman who has been exposed to rubella should contact her obstetrician immediately.
Rubella is typically mild in kids, who often can be cared for at home. Monitor your child's temperature and call the doctor if the fever climbs too high.
To relieve minor discomfort, you can give your child acetaminophen or ibuprofen. Do not give aspirin to a child with a viral illness because such use has been associated with the development of Reye syndrome, which can lead to liver failure and death.
