chronically active Epstein-Barr virus

Chronic active Epstein-Barr virus (EBV) infection is a rare condition where the virus remains active in the body over a long period, causing ongoing symptoms like fever, fatigue, swollen lymph nodes, and liver issues. Unlike the typical EBV infection that the immune system clears, in this chronic form, the virus persists and continues to cause inflammation and tissue damage. It may develop into serious health problems, including certain cancers. Diagnosis involves detecting persistent symptoms and evidence of active viral infection, often through blood tests. Treatment focuses on managing symptoms and reducing viral activity.
