Mononucleosis, also called mono, is an infection that is usually caused by the Epstein-Barr virus. Mono is spread through contact with saliva, mucus from the nose and throat, and sometimes tears or blood.
You can get mono by kissing a person who is infected. Or you may get it by sharing eating utensils or a drinking glass with someone who has mono.
Mono may cause your spleen to swell. The spleen is an organ in the upper left side of your belly. A blow to the belly can cause a swollen spleen to break open. In very rare cases, the spleen may burst on its own.
Most people recover fully after several weeks. But it may take several months before your normal energy is back. The lymph nodes in your neck may be larger than normal for up to 1 month. Getting lots of rest and keeping your schedule light will help you feel better. Time helps you recover.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
