Mononucleosis prevention

Majority of mononucleosis syndromes are caused by Epstein-Barr virus, and most people become infected with EBV sometime during their lives with an estimated 90-95% population aged more than 21 years demonstrate antibody to EBV.

The transmission of the virus requires intimate contact with the saliva of an infected person and rarely occurs via air or blood. Therefore, the most reasonable way to prevent mono is to avoid close contact with infected saliva.
