Which symptom is not associated with Rubella infection in pregnancy?

Rubella infection during pregnancy can lead to a range of congenital defects collectively known as congenital rubella syndrome (CRS). This syndrome is characterized by several specific teratogenic effects. Among these, deafness and cataracts are well-documented complications associated with rubella. Deafness is the most common manifestation, occurring in a significant number of cases. Cataracts can also develop, often resulting in vision impairment.

Retinopathy, though less commonly emphasized than deafness and cataracts, can occur in infants affected by CRS, contributing to visual impairments.

Hydrops fetalis, on the other hand, is not a characteristic complication of rubella infection in pregnancy. Although infections like parvovirus B19 and cytomegalovirus (CMV) are associated with hydrops, rubella typically does not lead to this condition. Therefore, the choice that identifies hydrops as a symptom not associated with rubella infection in pregnancy is correct.
