Kissing Disease and its Link to Cancer
Epstein-Barr virus (EBV) is a type of herpes virus called herpes 4 virus that spreads through saliva and other body fluids. It causes a disease named mononucleosis in humans, also known as the kissing disease. It is because it is culturally regarded as notorious for spreading through lip kissing.
Although it spreads primarily through saliva, sharing drinks and utensils or being in close contact with someone infected can also spread the virus.
