Definition & Meaning of "epstein-barr virus"

What is the "epstein-barr virus"?

The epstein-barr virus (EBV) is a common virus in the herpesvirus family. It is mainly known for causing infectious mononucleosis, often referred to as mono. EBV is spread through saliva and close contact with infected individuals. Most people are infected with EBV at some point in their lives, often during childhood or adolescence, and may not experience any symptoms or only mild ones. However, EBV can cause symptoms such as fever, sore throat, swollen glands, fatigue, and enlarged spleen or liver in some individuals. In addition to infectious mononucleosis, EBV has been linked to certain cancers. Treatment for EBV infection typically involves rest, fluids, and over-the-counter pain relievers to ease symptoms.
