Introduction

Infectious mononucleosis (mono), or glandular fever, is often called the kissing disease. The label is only partly true. The virus that causes this disease is transmitted through saliva, so kissing can spread the virus, but so can coughing, sneezing, or sharing a glass or food utensil. Mononucleosis isn't as contagious as some other infections, such as the common cold.

The cause of mononucleosis is the Epstein-Barr virus, although similar signs and symptoms are sometimes caused by cytomegalovirus (CMV). Full-blown mononucleosis is most common in adolescents and young adults. Young children usually have minimal symptoms, and the infection often goes unrecognized. In lesser developed countries, mononucleosis is more frequently acquired at a young age, so classic signs and symptoms of mononucleosis aren't as common as they are in developed nations.

Mononucleosis usually isn't very serious, although the virus remains in your body for life. Most people have been exposed to the Epstein-Barr virus by the time they're 35 years old and have built up antibodies. They're immune and won't get mononucleosis again. Treatment mostly involves bed rest and getting adequate fluids.
