Infectious mononucleosis can be caused by either cytomegalovirus (CMV) or Epstein-Barr virus (EBV). Both of these viruses belong to the Herpesviridae family. The classical virus that causes mono and a positive monospot test is the Epstein-Barr virus. Both are very common viruses that usually just cause a cold. In some people, usually teens and young adults, they can cause "mono." The form caused by the EBV is by far the most common.
Infectious mononucleosis, glandular fever or "Mono" is caused by the Epstein-Barr Virus (EBV), a member of the herpes group (human herpesvirus 4). It is spread by saliva especially by kissing, and other direct contact, like in other viruses, for example, flu and colds. Use the same precautions, and good hand washing techniques.
"Mono" or mononucleosis can be caused by Epstein-Barr virus (and less commonly by human cytomegalovirus).
