What Is CMV?

Cytomegalovirus (also called CMV) is the most common congenital viral infection in the world. CMV is transmitted (passed on) from a mother to her unborn child.

Anywhere from 1 in 200 to 3 in 200 newborns are born with congenital CMV (congenital means “born with”). Congenital CMV is also called cCMV.

CMV, Disabilities, & Hearing Loss

CMV is a serious infection. Of newborns who are born with cCMV, up to one in five will have permanent disabilities. Hearing loss is the most common permanent disability for CMV. 

What Are the Symptoms of CMV Infection?

Babies and infants can have different symptoms for CMV. Some babies will have no symptoms at all (called asymptomatic or aCMV). Other babies will have symptoms of CMV that affect one or more of their organs.

Sensorineural Hearing Loss (SNHL) & CMV

Some doctors count a type of hearing loss called sensorineural hearing loss (SNHL) as a symptom of CMV. Sensorineural hearing loss happens when the inner ear becomes damaged.

Other problems associated with CMV include the following:

  • hepatitis
  • low levels of platelets in the blood (thrombocytopenia)
  • bleeding in the skin (petechiae)
  • swelling in the liver & spleen (hepatosplenomegaly)
  • intrauterine growth restriction
  • central nervous system problems
  • inflammation inside the eye’s retina (chorioretinitis)

You can learn more about CMV from the National CMV Foundation. You can also learn about the National Institute of Health's clinical trial on Valear, a clinical trial that studies CMV in babies.
