Definition: Mononucleosis, commonly known as mono, is a viral infection that often affects teenagers and young adults. It is caused by the Epstein-Barr virus (EBV) and can be spread through contact with infected saliva, such as through kissing or sharing drinks.
Importance: Mono can cause a range of symptoms, including fatigue, sore throat, swollen lymph nodes, fever, and headaches. While most cases are mild and resolve on their own within a few weeks, some people may experience more severe symptoms that require medical attention.
