Mononucleosis, also known as the “kissing disease,” is easily transmitted to others through kissing, as well as sharing food, a cup, utensils or straws.
Dr. Gelman says that college students are more prone to developing mononucleosis, due to a lowered resistance and living in close quarters with other students.
“People can look as healthy as can be, but you have no idea what kind of diseases they are carrying,” says Dr. Gelman. “To protect yourself, know the person you are kissing.”
If you’re still in the mood—and you and your partner are healthy—stealing some smooches may benefit your oral health by increasing saliva production. Saliva helps to wash away food particles and cavity-causing bacteria. It also protects teeth from decay by neutralizing harmful acids.
