Which infection is passed to fetuses from mothers and can lead to neurological abnormalities in newborns?

Congenital Cytomegalovirus (CMV) is recognized as the most common congenital viral infection and is specifically known for its potential to cause neurological abnormalities in newborns. CMV can be transmitted from mother to fetus during pregnancy and poses significant risks, including developmental delays, hearing loss, and vision problems in the child.

When the mother is infected with CMV, the virus can cross the placenta and infect the developing fetus, leading to a range of neurological and developmental issues. The effects can vary from mild to severe, depending on the timing and severity of the maternal infection.

While congenital rubella syndrome can also lead to serious birth defects and has its own neurological impacts, CMV is more prevalent and often goes unnoticed, as many mothers may not exhibit symptoms during pregnancy. Similarly, maternal listeriosis and HIV can affect the fetus, but they do not specifically lead to the same pattern of neurological abnormalities associated with CMV infection. Thus, when considering infections that can directly cause neurological issues in newborns due to maternal transmission, congenital CMV is the focal point of concern.
