CMV is a common viral infection, especially among young children. Congenital CMV occurs when the infection is passed across the placenta from a pregnant woman to her developing baby. Some babies with congenital CMV infection show signs of disability at birth, while others are born healthy.
If you have CMV during pregnancy, you have a 1-in-3 chance (33 percent) of passing it to your baby. CMV is the most common virus passed from mothers to babies during pregnancy. About 1 to 4 in 100 women (1 to 4 percent) have CMV during pregnancy. Most babies born with CMV donât have health problems caused by the virus. But CMV can cause problems for some babies, including microcephaly. This is a birth defect in which a babyâs head is smaller than expected, compared to babies of the same sex and age. You can pass CMV to your baby at any time during pregnancy.
