Most people have been exposed to Epstein-Barr virus (EBV), which causes mono, by the time they reach adulthood. They likely won't have symptoms, but they can spread the virus to others every now and then throughout their lifetime.

- If a person is first infected with the virus as a teen or young adult, he or she is likely to develop symptoms of mono.
