“Why didn’t anyone tell me about this virus?” is a frequent response I hear from parents upon learning their newborn is infected with cytomegalovirus, or CMV. Although more than half of the U.S. population will be infected with CMV by the age of 40 and the disease is common worldwide, few people have ever heard of it.
CMV belongs to the same virus family as cold sores and chickenpox and, like those viruses, lives in the body for life. Most children and adults experience very mild or even no symptoms with their initial infection. A healthy immune system is typically able to keep CMV under control so people don’t become sick or even know the virus is living in their body.
