Rubella (German Measles)
What is rubella?
Rubella is sometimes called German measles. It is a viral infection. It usually causes a mild illness in children. Adults have a slightly more severe illness. The disease is spread person-to-person through droplets coughed or sneezed into the air by an infected person. It takes 2 to 3 weeks after exposure for symptoms to develop. The illness is mostly mild. But the virus can cause serious birth defects in pregnant women. A vaccine is effective in preventing rubella. Because of successful vaccine programs, rubella is no longer found in the U.S. But it's still common in other countries.
What causes rubella?
Rubella is caused by a virus. It is spread from person-to-person through droplets coughed or sneezed into the air by an infected person. Most outbreaks of rubella happen among young adults and adults who have not been vaccinated and have not had the disease before.
Who is at risk for rubella?
If you have not had the vaccine or never had rubella, you are at risk for the disease.
What are the symptoms of rubella?
Each person may have different symptoms. But these are the most common symptoms of rubella:
- Rash that usually begins on the face and moves to the trunk, arms, and legs (lasts about 3 days)
- Slight fever
- Enlarged lymph nodes
Rubella in pregnant women may cause serious complications in the fetus. This includes a range of severe birth defects.
The symptoms of rubella may look like other health problems. Always talk with your healthcare provider for a diagnosis.
How is rubella diagnosed?
Along with a complete health history and medical exam, diagnosis is often confirmed with blood tests.
How is rubella treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
Treatment for rubella is usually limited to acetaminophen for fever. There are no medicines to treat the virus infection itself.
What are possible complications of rubella?
For most people, rubella is a mild disease and does not cause complications. If a woman is infected with the disease while pregnant, her unborn baby can develop defects. Possible birth defects caused by rubella include:
- Congenital cataracts
- Heart defects
- Intellectual disability
- Liver and spleen damage
Can rubella be prevented?
The best protection against rubella is the measles, mumps, and rubella (MMR) vaccine. It protects against these 3 viruses. MMR makes most people immune to rubella (along with measles and mumps). Also, people who have had rubella are immune for life.
Usually, the first dose of the MMR vaccine is given when a child is 12 to 15 months old. A second dose is often given at 4 to 6 years of age. Women who are considering pregnancy should talk with their healthcare provider about being tested for immunity to measles, mumps, and rubella. If not protected, it's best to get vaccinated at least 4 weeks before trying to become pregnant. Teens and adults who are not up to date on their MMR vaccines should talk with their healthcare provider. Unvaccinated people can get rubella while traveling to countries where the disease is common.
When should I call my healthcare provider?
Rubella usually goes away on its own. But tell your healthcare provider if:
- Your symptoms get worse or you have new symptoms.
- You are pregnant and aren't sure if you have been vaccinated against rubella.
- You get a severe headache, stiff neck, earache, or problems with your vision either during the measles or afterward.
