Infectious mononucleosis, also known as glandular fever or “mono,” is an infectious disease affecting certain blood cells.
Sometimes called the “kissing disease,” mononucleosis is quite prevalent in teenagers and young adults, particularly college students, and is most often caused by the Epstein-Barr virus (EBV). It is estimated that at least 25 percent of individuals in this age group who contract EBV will go on to develop infectious mononucleosis.
