Cytomegalovirus (CMV) is a common virus that can infect almost anyone. In fact, the majority of adults are chronically (permanently) infected with it. Usually the virus is "silent" (does not cause any symptoms) and is not detected in the blood when checked.
In transplant patients, however, it can be cause for great concern as the viral infection can become active, causing different types of issues. It can lead to transplanted organ failure and, in some cases, even death.
While there could be several antiviral medications available to prevent or treat CMV, CMV infections among transplant recipients do not always respond to the currently available treatments.
