Mononucleosis Prevention

Mononucleosis (mono) is a viral infection that causes swelling of the lymph nodes. About 35 to 50 percent of those with the Epstein-Barr Virus will develop mono. The good news, however, is once someone has had mononucleosis the chances of ever having it again are very low. Symptoms include a soar throat, fever, swollen lymph glands, an enlarged spleen and fatigue.

  1. Mono Transmission

    • The virus spreads through saliva and can be contagious for up to 2 months; symptoms may last up to 4 months. However, mono symptoms may take 4 to 6 weeks to appear. According to the Centers for Disease Control, mononucleosis is impossible to prevent, because even symptom-free people may carry the virus in their saliva. Diagnosis is only confirmed with a blood test.

    Don't Share

    • Since mono is passed through saliva, do not share any of the following: drinks, utensils, lipstick or a toothbrush. Do not touch anything that has been near the mouth of a person with mono.

    Other Prevention Tips

    • Wash your hands frequently. Avoid others with a soar throat. Stay away from crowded areas during cold and flu season. Do not give blood if you have mononucleosis. Wash objects that may have been around saliva.
