CMV is a very common viral infection that affects people of all ages around the world. Once an individual is infected with CMV, it remains in the body throughout their life and can be reactivated when they become immune-compromised. Most people don’t realize that they have acquired a CMV infection when they are healthy. CMV can be a cause for concern in pregnant women and immune-compromised individuals. Congenital CMV can cause morbidity and even death and is a leading cause of deafness, learning disabilities and intellectual disability.
