Causes

By Mayo Clinic staff

The cause of mononucleosis is the Epstein-Barr virus, although similar signs and symptoms are sometimes caused by cytomegalovirus.

Mononucleosis usually isn't very serious. Most adults have been exposed to the Epstein-Barr virus and have built up antibodies. They're immune and won't get mononucleosis again.
