​Rubella (German Measles) and Pregnancy

• Rubella is a virus which will produce a mild illness in the pregnant mother but could produce severe problems in the developing baby, also referred to as Congenital Rubella Syndrome (CRS).
• The unborn child is most at risk of developing CRS if a pregnant woman is infected with the virus in the first three months of pregnancy.
• It is very rare for problems to result if infected after the 20th week of conception.
• Infants with CRS may be born deaf or blind, have damage to their hearts, or mental disabilities.
• CRS is rare in Ontario. Fourteen cases of CRS were reported to the Ministry of Health and Long-Term Care from 1990-2004, which is about one per year.
• Rubella is not very common as 95% of children have now been immunized as part of their routine immunization schedule

Protection

• Before becoming pregnant, check your immunity to rubella (there is a vaccine – MMR – that protects an individual from rubella)
• If you are not immune, have the MMR vaccine and wait three months before becoming pregnant
• If you have been exposed to rubella in pregnancy and do not know your immunity, contact your doctor immediately
