The disease develops as a complication or progression of either Epstein–Barr virus-positive infectious mononucleosis (EPV+ IM) or chronic active Epstein–Barr virus infection (CAEBV)., [1] that is, as a worsening of the signs/symptoms some three weeks after the onset of an EBV+ IM-like disease or an any time during the course of CAEBV.
There are several forms of Epstein–Barr virus (EBV) infection. These include asymptomatic infections, the primary infection, infectious mononucleosis, and the progression of asymptomatic or primary infections to: 1) any one of various Epstein–Barr virus-associated lymphoproliferative diseases such as chronic active EBV infection, EBV+ hemophagocytic lymphohistiocytosis, Burkitt's lymphoma ...
Chronic active EBV infection or in its expanded form, chronic active Epstein–Barr virus infection is a very rare and often fatal complication of Epstein–Barr virus (EBV) infection that most often occurs in children or adolescents of Asian or South American lineage, although cases in Hispanics, Europeans and Africans have been reported. [1]
Infectious mononucleosis (IM, mono), also known as glandular fever, is an infection usually caused by the Epstein–Barr virus (EBV). [2] [3] Most people are infected by the virus as children, when the disease produces few or no symptoms. [2] In young adults, the disease often results in fever, sore throat, enlarged lymph nodes in the neck, and ...
The Epstein–Barr virus (EBV) is one of the nine known human herpesvirus types in the herpes family, and is one of the most common viruses in humans. EBV is a double-stranded DNA virus and is also called human herpesvirus 4 (HHV-4). [2] Epstein–Barr virus (EBV) is the first identified oncogenic virus, or a virus that can cause cancer. EBV ...
The Gammaherpesvirinae subfamily is associated with episomal latency established in cells of the immune system, such as B-cells in the case of Epstein–Barr virus. [3] [4] Epstein–Barr virus lytic reactivation (which can be due to chemotherapy or radiation) can result in genome instability and cancer. [5]
EBV reactivation can occur in the B lymphocytes of CLL/SLL and lead to a severer form of CLL/SLL and/or to Richter's transformation. [23] RT transformation has been reported to rarely underlie the development of DLBCL-RT but is associated with the development of type 1 HL-RT in 75% of 51 type 2 cases and 65% of 26 type 1 cases.

In immunocompetent patients, Epstein-Barr virus can cause infectious mononucleosis in adolescents, which is otherwise asymptomatic in children during their childhood. However, in immunosuppressed transplant patients, the lack of T-cell immunosurveillance can lead to the proliferation of these EBV-infected B-lymphocytes. [citation needed]
