Rubella is a viral infection. It is contagious and spreads from person to person.
Rubella is also called German measles, or three-day measles. However, rubella is caused by a different virus than measles.
A vaccine can prevent rubella
The best way to prevent rubella is to get the vaccine.
Rubella is contagious and spreads from person to person. It can spread by direct contact or droplets in the air. An infected person can spread droplets when they talk, cough, or sneeze.
Symptoms typically appear 12–23 days after the person is exposed to the virus.
- In younger children rubella usually starts with a rash on the face and neck. The rash can last two or three days. The rash can be hard to see on dark skin, but it might feel rough or bumpy.
- Older children and adults may have a low-grade fever, swollen glands in the neck, and a respiratory infection before the rash begins.
- Up to 70% of women with rubella have joint pain.
Rubella can be dangerous in pregnant people because it can harm the baby. A fetus has a 90% chance of being born with congenital rubella syndrome if a woman catches rubella in early pregnancy. This syndrome can cause deafness, blindness, developmental disabilities, heart defects, and/or death just after birth.
A doctor can confirm the disease through a blood test. There is no specific treatment for rubella.
The best way to avoid rubella is to get a vaccine.
- All children.
- Women who are considering pregnancy and aren’t vaccinated.
- People 6 months of age and older who’ll be traveling to any country outside the United States and aren’t vaccinated.
The CDC recommends children get two doses of the MMR vaccine:
- First dose at 12–15 months of age.
- Second dose at 4–6 years of age.
Teens and adults also should be up to date on MMR vaccinations. Find out if you and your children are up to date. Check our Department of Health Services (DHS) Wisconsin Immunization Registry.
