CMV Action

Providing lived experiences and connections to families who have children diagnosed with CMV..

CMV, or Cytomegalovirus, is a common virus that can infect people of all ages. Once CMV is in a person’s body, it stays there for life. Most healthy adults and children who become infected will have no signs or symptoms and no long term effects from CMV. It can however pose serious risks to unborn babies if a pregnant woman catches it for the first time. Congenital CMV is when a baby has been infected before birth. It is one of the leading causes of hearing loss in children and one of the main causes of childhood disability.
