She is very concerned and would consider termination if it were earlier in the pregnancy. What are the current predictions of risk for her fetus? ANSWER: Based on review of all available studies, we could not detect a single case of congenital varicella syndrome in the third trimester of pregnancy (0/208), as compared with 5/645 (0.78%) in the first and 9/592 (1.52%) in the second trimester (P < .01 third vs first and second). You can reassure your patient.
