Congenital cytomegalovirus (CMV) infection refers to the transmission of CMV (a type of herpes virus) from a woman to her developing fetus. CMV usually does not cause symptoms when a healthy person becomes infected. However CMV can become a serious infection for a person with a weak immune system, like a developing baby. Infection causes varying degrees of hearing loss, vision loss, and intellectual disabilities in 80 to 90 percent of those infected in-utero (while in their mother’s wombs). Symptoms of prenatal infection in newborns may include low birth weight, jaundice, seizures, small head (microcephaly) and rash. Hearing loss, vision loss, and intellectual delays caused by the infection usually develop within the first few years of life. Women who are infected with the virus before pregnancy or after birth do not risk spreading the infection to their fetus or newborn. The condition only occurs if the first time a woman is infected with the virus is during the pregnancy. Because of this, the condition is less common in developing countries where pre-pregnancy exposure is more common than in developed countries. The best way to prevent congenital CMV infection is for pregnant women to avoid potential virus exposure. The virus is readily transmitted by exposure to bodily fluids, such as saliva, from an infected individual. A vaccine is currently being researched to help protect the fetuses in women who have not yet been exposed to the virus. Talk with your midwife or obstetrician if you are pregnant and think you may have been exposed to the CMV. Although there is currently no cure for congenital cytomegalovirus, there are various resources to help manage the condition and treat birth defects. Doctors seek help from various therapists and community services to provide support and care for a baby affected by prenatal exposure to CMV.
