Who Is Affected by Infectious Mononucleosis

Who Is Affected by Infectious Mononucleosis

Infectious mononucleosis (mono) occurs in about 1 out of 2,000 people every year. People between the ages of 15 and 24 are most likely to have symptoms of mono. 1

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 lives.

  • Young children infected with the virus usually have no symptoms or only mild symptoms.
  • 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.
