[Clinical picture of Herpesviridae infections among immunocompromised patients: bone marrow and solid organ transplants recipients].

The human herpes virus (HHV) family (herpesviridae) are large DNA viruses containing eight important, ubiquitous human pathogens. This group of viruses encompasses: herpes simplex virus (HSV types 1 and 2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), HHV-6, HHV-7 (cause roseola or exanthema subitum in children) and Kaposi sarcoma herpes virus--(KSHV). The outstanding property of herpes viruses is lifelong persistence of infection and potential periodic reactivation, particularly often among immunocompromised patients.
