Infectious mononucleosis (often called "mono") is a common viral infection that causes fever, sore throat, and enlarged lymph nodes. Mononucleosis is most commonly caused by the Epstein-Barr virus (EBV), and it is most frequently diagnosed in teenagers and young adults.
Mononucleosis generally resolves without medical help, though it may last from weeks to months. Treatment is aimed at easing the symptoms of the illness, and it can usually be done at home with plenty of rest, fluids, and over-the-counter medications. Serious complications only rarely occur.
