Chronic haemodialysis patients are at high risk for infection because the process of haemodialysis (HM) requires vascular access for prolonged periods. The human Cytomegalo Virus (CMV) is a DNA virus belonging to the Herpesviridae family, Betaherpsvirnae subfamily and Cytomegalo virus gender, known as Human Herpes Virus Type 5, one of the main causes of morbidity. Acute CMV infection is characterized by system-wide viremia after which latency and lifelong persistence is established in selected cells such as CD34+ monocytes and hematopoietic progenitor cells in humans.
