The Epstein-Barr Virus (EBV) is a common virus that belongs to the herpesvirus family. It is best known for causing infectious mononucleosis, often referred to as "mono." Many people are infected with EBV during childhood or adolescence, and it usually remains dormant in the body after the initial infection. Most individuals do not experience severe symptoms, but some may develop fatigue, fever, and sore throat. EBV is also linked to certain cancers, such as Hodgkin's lymphoma and nasopharyngeal carcinoma. Good hygiene practices, like washing hands and avoiding sharing drinks, can help reduce the risk of transmission.
