What Is Mononucleosis?

Mononucleosis, otherwise called infectious mononucleosis, mono, glandular fever, or the kissing disease, is a viral infection caused by the Epstein-Barr Virus (EBV). It commonly affects teenagers but can affect people of any age. It is called kissing disease because the virus is present in the saliva, which gets transmitted through kissing. Apart from kissing, you can also get infected if you are exposed to the virus through an infected person coughing or sneezing near you and sharing a glass or utensils with an infected individual.

Infants and young children get infected when adults kiss them, but they usually show mild symptoms and the infection goes undiagnosed. This infection causes severe signs and symptoms in young adults and teenagers. As it is a viral infection, rest and fluids will help you recover fast. Spleen enlargement is the most common complication of mono. Anyone who gets infected with EBV once is mostly immune to it for the rest of life.
