Congenital Cytomegalovirus Infection is a condition that occurs when a pregnant woman passes the cytomegalovirus to her unborn baby. This virus can impact the baby's health and development before and after birth. It may affect various organs and systems in the body, potentially leading to long-term health issues. The primary impact of Congenital Cytomegalovirus Infection on health is its potential to cause complications that can affect the baby's overall well-being and quality of life.

What are the Types of Congenital Cytomegalovirus Infection?

Congenital Cytomegalovirus Infection can present in various forms, each affecting infants differently based on the severity and extent of their symptoms.

Symptomatic Congenital Cytomegalovirus Infection: Babies born with visible symptoms such as jaundice, enlarged liver or spleen, small head size, and developmental delays due to CMV infection during pregnancy.
Asymptomatic Congenital Cytomegalovirus Infection: Babies born without apparent symptoms but may develop hearing or vision problems later in life due to CMV transmission from the mother.
Severe Congenital Cytomegalovirus Infection: Involves serious health issues such as brain abnormalities, intellectual disabilities, seizures, and feeding difficulties in infants infected with CMV before birth.
Mild Congenital Cytomegalovirus Infection: Infants with subtle or minor symptoms like mild hearing loss, slight developmental delays, or no apparent health issues at birth but may still experience long-term effects.
Late-Onset Congenital Cytomegalovirus Infection: Occurs when symptoms or complications of CMV infection manifest later in infancy, childhood, or even adulthood, leading to health challenges like hearing loss or cognitive impairments.
