Cytomegalovirus (CMV)

Cytomegalovirus (CMV) is a common herpes-type virus that can cause fever, chills, sore throat, swollen glands, body aches, and fatigue. Symptoms are similar to those of an Epstein-Barr viral infection, which is the primary cause of mononucleosis (mono).

CMV can be spread through saliva, infected blood products, and sexual contact with an infected person.

Normally, healthy people have few, if any, symptoms. However, the illness can be much more severe in people who have impaired immune systems (such as those who have cancer or AIDS). Also, a baby can get CMV from the mother during pregnancy or by coming into contact with her body fluids during birth. This can result in severe brain injury and other health problems.
