This article explains how Epstein-Barr virus spreads, its common symptoms, and preventive tips. It emphasizes transmission routes like saliva and shared items, especially among teenagers, and highlights the importance of hygiene to avoid infection.

The Epstein-Barr virus (EBV) is the primary pathogen behind infectious mononucleosis, commonly called "mono" or the "kissing disease." It primarily transmits through close contact, especially kissing, making it highly contagious among teenagers aged 14-18. Many carriers remain asymptomatic, but when symptoms manifest, they mimic cold or flu symptoms, including tiredness, fever, sore throat, swollen lymph nodes, and muscle aches. Fatigue can linger for weeks. The virus spreads mainly through saliva, shared utensils, and personal items, with potential transmission via blood and sexual contact. Good hygiene and not sharing personal objects help lower infection risk.
