If you're pregnant and have rubella, you can pass it to your baby.
Rubella infection in pregnant women can cause severe birth defects in the baby. The conditions that result from a mother being infected with rubella during pregnancy are together known as congenital rubella syndrome, or CRS.
Who is at risk?
CRS affects developing babies. A mother infected during the first 12 weeks of pregnancy (first trimester) has the highest risk of having a baby with CRS.
Conditions of congenital rubella syndrome
Many different conditions can affect developing babies if the mother is infected with rubella virus, including:
- Deafness
- Vision problems
- Heart problems
- Low birth weight
- Organ damage
- Intellectual disabilities
- Miscarriage
Prevention
- Rubella can be prevented with the MMR vaccine.
- Check with your doctor to make sure you are vaccinated before you get pregnant.
- You should not get the MMR vaccine if you are pregnant because the vaccine contains weakened live virus.
