What's Mononucleosis?


Say: mon-oh-new-klee-OH-sis

Did you know that mononucleosis (mono) is also called the kissing disease? That's because someone who has this infection can pass it to others by kissing them. But it also spreads when people with mono share toothbrushes, straws, or anything that might have their saliva on it.
