Change me!!!Cytomegalovirus (CMV) is a common human virus. Cytomegalovirus DNA test is a highly sensitive and specific PCR test used mostly in the diagnosis of congenital CMV infection. An active Cytomegalovirus infection can cause prolonged high fever, chills, severe tiredness, a generally ill feeling, headache, and an enlarged spleen. Most newborns infected with Cytomegalovirus have no symptoms at birth, but, in some cases, symptoms will appear over the next several years. These include mental and developmental problems and vision or hearing problems. In rare cases, a newborn can have a life-threatening infection at birth. Infants and children who get CMV infection after birth have few, if any, symptoms or complications. When symptoms do appear, they include lung problems, poor weight gain, swollen glands, rash, liver problems, and blood problems.
