Causes
Infectious mononucleosis is caused by the Epstein-Barr virus (EBV), which is a member of the herpes virus family. The infection is spread through close contact with an infected person, such as through saliva or other bodily fluids. The virus can also be spread through blood transfusions or organ transplants from an infected donor.
