If you have an adolescent child, then you’re probably familiar with the “kissing disease.” Mononucleosis, known by the shorter version, “mono” to which it will be referred to as now, has troubled preteens and teens alike for years. While adults can still contract the disease, it is very rare because most adults are immune. Mono is a viral infection that can completely drain your child of energy. It also can cause swelling of the glands and tonsils, a sore throat, swollen sinuses and more.

Mono is caused by the “Epstein-Barr” virus, commonly referred to as EBV. It is easily transmitted through saliva, thus gaining the “kissing disease” designation. In fact, mono can even be spread through tears. Another form of transportation for the mono virus is the mucus of both the nose and throat and therefore sneezes and coughs. The best way to avoid transmitting mono to others is to avoid all forms of kissing and sharing drinks, toothbrushes or eating utensils.

An interesting fact is that if you have had mono, you will retain the virus forever. It will not cause any symptoms, however it will become active from time to time and it’s during this time it can be spread to others.
