Question

Quizplus · Accepted Answer

The teratogenic effects of rubella infection are most severe when the infection occurs during the first trimester of pregnancy. This is because during this time, the vital organs and systems of the fetus are developing, and the virus can interfere with this process, leading to a range of birth defects and developmental disabilities. Infection during the second and third trimesters may also cause problems, but they are generally less severe.
