What is the primary transmission mode for the TORCH infections?

The primary transmission mode for TORCH infections is from mother to fetus. TORCH refers to a group of congenital infections that can have serious consequences during pregnancy. The acronym stands for Toxoplasmosis, Other (which includes infections like syphilis and varicella), Rubella, Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV).

These infections are specifically significant because they can be transmitted through the placenta during pregnancy or at the time of delivery, posing risks to the developing fetus. For instance, a maternal infection with rubella can lead to congenital rubella syndrome, which can cause severe birth defects or developmental issues in the child. Similarly, infections like syphilis can result in stillbirth or congenital infections that might affect the newborn.

Understanding the mode of transmission emphasizes the importance of prenatal care, screening, and vaccinations to protect both the mother and the fetus from these potentially serious infections. Other transmission modes, such as airborne or vector-borne, do not pertain to TORCH infections, which is why they do not represent the correct answer in this context. Direct contact is also not the primary concern within the TORCH group, particularly regarding maternal-infant transmission, making mother-to-fetus the key transmission route
