Congenital rubella syndrome may occur when a pregnant woman is infected with rubella. Rubella is a viral illness usually resulting in a mild rash. In congenital rubella syndrome, the infection can lead to severe birth defects, especially if acquired in the first 8 weeks of pregnancy. Infection with rubella during pregnancy can also lead to miscarriage or stillbirth.

Congenital rubella syndrome is caused by the rubella virus. A pregnant woman can contract from another person through tiny droplets in the air. The mother's rubella infection can harm a developing fetus, especially during the first trimester of pregnancy.
