Quick Question.. I've had It once. Can I get it again?
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. http://www.cnn.com/HEALTH/library/DS/00352.html
