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 ...
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 ...
Characteristic findings that are also diagnostic criteria for the disorder are: 1) symptoms similar to those in infectious mononucleosis but persist for >3 months; 2) high blood levels of EBV DNA (i.e. >25 viral copies per mg of total DNA); 3) histologic evidence of organ disease; 4) presence of EBV RNA (e.g. an EBER) in an affected organ or ...
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.

Boys with X-linked immunodeficiency syndrome are at a higher risk of mortality associated with Epstein–Barr virus infections, and are predisposed to develop a lymphoproliferative disorder or lymphoma. [citation needed] Children with common variable immunodeficiency (CVID) are also at a higher risk of developing a lymphoproliferative disorder.
Reactive lymphocytes have been found to accumulate in areas of inflammation like the liver and pharynx of individuals with infectious mononucleosis and skin window preparations. In infectious mononucleosis, the atypical lymphocytes are one component of a normal immune system that helps to control potentially fatal Epstein-Barr virus -induced B ...
The main risk factors for PTLD are the degree of immune suppression and the presence of Epstein-Barr virus. Specifically, higher levels of T cell immunosuppression increase the risk PTLD. Individuals who have never been infected by the Epstein-Barr virus (EBV negative) who receive an organ from a donor with prior EBV infection are 24 times more ...
The mononuclear spot test or monospot test, a form of the heterophile antibody test, [1] is a rapid test for infectious mononucleosis due to Epstein–Barr virus (EBV). It is an improvement on the Paul–Bunnell test. [2] The test is specific for heterophile antibodies produced by the human immune system in response to EBV
