Rubella (German Measles)

What is rubella?

Rubella, sometimes called German measles, 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 before symptoms to develop after exposure. Although the illness is mostly mild, the virus can cause serious birth defects in pregnant women. The vaccine is effective in preventing rubella.

What causes rubella?

Rubella is caused by a virus and is spread from person-to-person through droplets coughed or sneezed into the air by an infected person. Most outbreaks of rubella occur among young adults and adults who have not been vaccinated or 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?

The following are the most common symptoms of rubella. However, each person may experience symptoms differently. Symptoms may include:

  • Rash (usually begins at the face and progresses to the trunk, arms and legs, and lasts about 3 days)
  • Slight fever
  • Enlarged lymph nodes
  • Headache

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 medical conditions. Always consult your doctor for a diagnosis.

How is rubella diagnosed?

Along with a complete medical history and medical exam, diagnosis is often confirmed with a throat culture and blood testing.

How is rubella treated?

Specific treatment for rubella will be determined by your health care provider based on:

  • Your overall health and medical history
  • Extent of the condition
  • Your tolerance for specific medications, procedures, or therapies
  • Expectations for the course of the condition
  • Your opinion or preference

Treatment for rubella is usually limited to acetaminophen (such as Tylenol) for fever.

What are the 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:

  • Deafness
  • Congenital cataracts
  • Heart defects
  • Intellectual disability
  • Liver and spleen damage

Can rubella be prevented?

Measles, mumps, and rubella (MMR) is a childhood vaccination that protects against these 3 viruses. MMR makes most people immune to rubella. People who have had rubella are immune for life.

Usually, the first dose of the MMR vaccine is given when a child is 12 months old. A second dose is given at 4 to 6 years of age. However, if 28 days have passed since the first dose was given, a second dose may be given before the age of 4.

When should I call my health care provider?

Rubella usually resolves on its own. However, tell your health care provider if:

  • If your symptoms get worse or you have new symptoms
  • If you are pregnant and aren't sure if you have been vaccinated against rubella
  • If you get a severe headache, stiff neck, earache, or problems with your vision either during the measles or afterwards
