What is Congenital Cytomegalovirus?

Congenital Cytomegalovirus (CMV) is a viral infection passed from mother to baby during pregnancy. This virus can cause a range of health issues in newborns, from mild to severe. Understanding CMV is crucial for expecting parents and healthcare providers.

CMV is a common virus: Most people will be infected with CMV at some point in their lives, often without knowing it.
Transmission through bodily fluids: CMV spreads through saliva, urine, blood, tears, semen, and breast milk.
Primary infection in pregnancy: If a woman contracts CMV for the first time during pregnancy, the risk of passing it to the baby is higher.
Reactivation of CMV: Women who have had CMV before can reactivate the virus during pregnancy, potentially affecting the baby.
CMV is part of the herpesvirus family: This family includes other viruses like herpes simplex, chickenpox, and Epstein-Barr virus.

Symptoms and Diagnosis

Recognizing the symptoms and getting a proper diagnosis can help manage CMV effectively. Symptoms can vary widely, making diagnosis challenging.

Many babies show no symptoms at birth: Around 90% of babies with congenital CMV appear healthy at birth.
Common symptoms in newborns: Symptoms can include jaundice, low birth weight, enlarged liver and spleen, and a small head size.
Hearing loss: One of the most common long-term effects of congenital CMV is hearing loss, which may not be apparent at birth.
Vision problems: Some babies may develop vision issues, including inflammation of the retina.
Neurological issues: CMV can cause developmental delays, motor skill issues, and intellectual disabilities.
Blood tests for diagnosis: CMV can be diagnosed through blood tests that detect the virus or antibodies.
Urine and saliva tests: These tests can also detect CMV in newborns.

Frequently Asked Questions

QWhat exactly is congenital cytomegalovirus?

Congenital cytomegalovirus, or CMV, is a virus that can be passed from a pregnant person to their baby during pregnancy. It's a common virus that belongs to the herpesvirus family, which also includes the viruses that cause cold sores, chickenpox, and mononucleosis. Most folks with CMV don't even know they have it because it often doesn't cause symptoms. But in babies, it can lead to more serious health issues.

QHow common is congenital CMV infection?

It's more common than many people realize. Each year, about 1 in 150 babies are born with congenital CMV infection. However, not all of these babies will have symptoms or long-term health problems. It's one of the leading causes of hearing loss and developmental disabilities in children.

QCan congenital CMV be prevented?

While there's no guaranteed way to prevent CMV infection, there are steps pregnant folks can take to lower their risk. Washing hands often with soap and water, especially after changing diapers, handling children's toys, or feeding a child, can help. Avoiding sharing food, utensils, drinks, and personal items like toothbrushes with young children can also reduce risk, as young ones are often carriers of the virus.

QWhat are the symptoms of congenital CMV in newborns?

Many babies born with CMV won't show any signs at birth. For those who do, symptoms might include a low birth weight, yellow skin and eyes (jaundice), a rash with small bruises, enlarged spleen or liver, and seizures. Because these symptoms can be associated with other conditions, testing is necessary to confirm CMV.

QHow is congenital CMV diagnosed?

Congenital CMV is diagnosed through a series of tests. For newborns, doctors can test saliva, urine, or blood within the first two to three weeks of life to look for the virus. If a baby tests positive, further assessments might be needed to determine the extent of the infection and any potential impacts on health.

QWhat treatments are available for congenital CMV?

Treatment for congenital CMV can vary depending on the severity of the infection and the symptoms present. Antiviral medications may be prescribed to help lessen the severity of symptoms.
