Infectious mononucleosis, (also known as the kissing disease, or Pfeiffer's disease, in North America as mono, and more commonly known as glandular fever in other English-speaking countries), is a disease seen most commonly in adolescents and young adults, characterized in teenagers by fever, sore throat, muscle soreness, and fatigue. Mono typically produces a very mild illness in small children. White patches on the tonsils or in the back of the throat may also be seen, (resembling strep throat). Mononucleosis is usually caused by the Epstein-Barr virus (EBV), which infects B cells (B-lymphocytes), producing a reactive lymphocytosis and atypical T cells (T-lymphocytes) known as Downey bodies. less
