Question: Is it true you can get mononucleosis from kissing someone or drinking from his/her cup?
Answer: It is true. Any individual that has mono can effectively infect someone else with mono if the other individual has shared any utensils, or there's been an exchange of saliva. So generally, when we have individuals that have been diagnosed with mono, we strongly recommend not sharing any drinking vessels, cups, utensils, such as spoons, knives, forks, eating out of the same plate and even sharing toothbrushes. Those things are often discouraged until the patient that does have mono symptoms have completely improved.
