If you're pregnant, testing to determine whether you've ever been infected with CMV can be important.
Pregnant women who have already developed CMV antibodies have a very small chance of a reactivation infecting their unborn children. If your doctor detects a new CMV infection while you're pregnant, a prenatal test amniocentesis can determine whether the fetus has been infected. In this test, your doctor takes and examines a sample of amniotic fluid.
Amniocentesis is generally recommended when abnormalities that might be caused by CMV are seen on ultrasound. If your doctor suspects your baby has congenital CMV , it's important to test the baby within the first three weeks of birth. If your baby has CMV , your doctor likely will recommend additional tests to check the health of the baby's organs, such as the liver and kidneys.
Testing for CMV can also be important if you have a weakened immune system. Treatment generally isn't necessary for healthy children and adults. Healthy adults who develop CMV mononucleosis generally recover without medication.
Newborns and people who have weakened immunity need treatment when they're experiencing symptoms of CMV infection. The type of treatment depends on the signs and symptoms and their severity. Antiviral medications are the most common type of treatment. They can slow reproduction of the virus, but can't eliminate it. Researchers are studying new medications and vaccines to treat and prevent CMV. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition.
Some babies without signs of congenital CMV infection at birth may have hearing loss. Hearing loss may be present at birth or may develop later, even in babies who passed the newborn hearing test. A pregnant woman can pass CMV to her unborn baby. This can happen when a pregnant woman is infected with CMV for the first time or is infected with CMV again during pregnancy.
People who have frequent contact with young children may be at greater risk of CMV infection because young children are a common source of CMV. By the age of five years, one in three children has been infected with CMV, but usually does not have symptoms.
A woman who is infected with CMV can pass the virus to her developing baby during pregnancy. As a parent of a young child or a childcare provider, you may be able to lessen your risk of getting CMV by reducing contact with saliva and urine from babies and young children.
The saliva and urine of children with CMV have high amounts of the virus. Also, you should wash your hands after changing diapers. These cannot eliminate your risk of getting CMV but may lessen the chances of getting it.
