Persistent CMV viremia

What it means

Persistent or recurrent detection of cytomegalovirus (CMV) in the blood that occurs in the context of unusual susceptibility to infection.

Persistent CMV infection has important clinical relevance in the global population. Although immune-mediated control of CMV in healthy individuals prevents disease and overt clinical symptoms, immune dysregulation caused by immunosuppressive treatments in transplant and cancer patients, congenital immunodeficiencies, HIV/AIDS, and/or aging can result in CMV viremia, life threatening disease, and even death.
