When infection occurs in childhood, the virus most often produces no symptoms. While there are other illnesses falling under the broad classification of mononucleosis that can cause similar signs of mono (cytomegalovirus [CMV] infection is one example) and an increase in blood lymphocytes, the form caused by the EBV is by far the most common.
Individuals are believed to be the primary source of transmission of the virus. The fact that up to 95% of adults have antibodies to EBV suggests that prevention of the infection is difficult if not impossible. It is not known why some people develop the symptoms of mono while others appear to acquire the EBV without producing symptoms.
