- Rubella has a teratogenic effect on the fetus during the first trimester. It produces abnormalities in up to 40% of cases without interrupting the pregnancy.
- Immunity to rubella can be measured by a hemagglutination inhibition test (rubella titer).
This test identifies exposure to rubella infection and determines susceptibility in pregnant women.
In a woman, a titer greater than 1:8 indicates immunity.
