A pregnant patient asks about rubella exposure in the first trimester. What is the fetal risk and typical approach?

• A. Congenital rubella syndrome; highest risk in the first trimester; no antiviral treatment; counseling and monitor
• B. No fetal risk; continue pregnancy without monitoring
• C. Requires antiviral therapy
• D. Immediate termination is always required

Answer: (A)

When rubella exposure happens in early pregnancy, the fetus is at substantial risk for congenital rubella syndrome because organ development is most vulnerable then. The risk is highest in the first trimester and decreases as gestation progresses. There isn’t an antiviral treatment available to prevent or treat rubella during pregnancy, so the plan centers on thorough counseling about the fetal risks and careful monitoring of the pregnancy. This includes informing the patient about potential outcomes and engaging in appropriate fetal assessment and follow-up, rather than attempting medical therapy. Vaccination against rubella is not given during pregnancy, but rubella vaccination after delivery helps protect future pregnancies. The congenital rubella syndrome that can occur includes serious issues like cataracts, sensorineural deafness, and heart defects such as patent ductus arteriosus, among other consequences, which is why close counseling and monitoring are essential.
