Definition

Noun: A specific type of herpesvirus (Human gammaherpesvirus 4) that is one of the most common human viruses. It is best known as the primary cause of infectious mononucleosis ("mono") and is also associated with certain cancers and autoimmune conditions.

Usage and Examples

The term 'Epstein-Barr virus' is used as a proper noun to name this specific pathogen. * The doctor confirmed that her fatigue was due to an infection with the Epstein-Barr virus. * Research into the Epstein-Barr virus has revealed its complex relationship with the human immune system. * A blood test can detect antibodies to Epstein-Barr virus.

Advanced Usage and Context

• The virus is often abbreviated as EBV in medical and scientific literature.
  • Most adults have been exposed to EBV by age 40.
• It is frequently discussed in the context of EBV infection, EBV-associated diseases, or latent EBV (referring to the virus's dormant state in the body after initial infection).

Variants and Related Words

• EBV: The standard acronym for Epstein-Barr virus.
• Human herpesvirus 4 (HHV-4): The formal taxonomic name.
• Infectious mononucleosis: The most common symptomatic illness caused by primary EBV infection.
• Burkitt's lymphoma: A type of cancer strongly associated with EBV, particularly in certain regions of Africa.

Synonyms and Related Terms

Notes on Meaning

The definition focuses on the virus as an etiological agent (cause of disease). Its significance extends beyond causing mononucleosis to include: 1. Oncogenic potential: Its established link to certain malignancies like Burkitt's lymphoma, nasopharyngeal carcinoma, and some Hodgkin's lymphomas. 2. Persistence: Like other herpesviruses, it establishes a lifelong, usually dormant, infection in the host after the initial illness. 3. Transmission: It is primarily spread through bodily fluids, especially saliva.
