Congenital rubella is a condition that occurs in an infant whose mother is infected with the virus that causes German measles.
Congenital rubella occurs when the rubella virus in the mother affects the developing baby at a critical time, in the first 3 months of pregnancy. After the fourth month, the mother's rubella infection is less likely to harm the developing baby.
The number of babies born with congenital rubella has decreased dramatically since the introduction of the rubella vaccine.
Pregnant women who are not vaccinated for rubella and who have not had the disease in the past risk infecting themself and their unborn baby.
Call your health care provider if you have concerns about congenital rubella, if you are unsure of your vaccination status, or if you or your children need a rubella vaccine.
Vaccination prior to pregnancy can prevent congenital rubella. Pregnant women who are not immune to rubella should avoid contact with persons who have the virus.
