Mononucleosis, or mono, most often affects teenagers and children. If you get the virus as an adult, the symptoms can be much worse.
About 95 percent of adults ages 35 to 40 have been infected by mononucleosis, otherwise known as the "kissing disease." It's spread by saliva, mucus from the throat and nose, and in some cases, even from tears.
Therefore kissing, sharing food or utensils can cause mononucleosis. Once you are infected, the virus remains in your body for the rest of the life. While you cannot get full blown mono again, if your body gets run down or stressed out the virus can be reactivated, but this time around, the symptoms are less severe.
