CauseInfectious mononucleosis is caused by the Ebstein-Barr virus, which is a member of the herpes family. This family also includes the viruses that cause cold sores, chicken pox, genital herpes, and birth defects.

They had such mild cases that they thought it was just a cold or flu and their bodies were able to produce antibodies against ever having mono again.SymptomsIf symptoms do appear, they don't develop immediately.
