Definition
By Mayo Clinic staffCytomegalovirus (CMV) is a common virus that can infect almost anyone. Most people don't know they have CMV because it rarely causes symptoms. However, if you're pregnant or have a weakened immune system, CMV is cause for concern.
Once infected with CMV, your body retains the virus for life. However, CMV usually remains dormant if you're healthy. CMV spreads through body fluids, such as blood, saliva, urine, semen and breast milk. People with weak immune systems have a greater risk of becoming ill from CMV. If you're pregnant and develop an active infection, you can pass the virus to your baby.
There's no cure for CMV, but drugs can help treat newborns and people with weak immune systems.
