"Infectious mononucleosis (also known as EBV infectious mononucleosis or Pfeiffer's disease and colloquially as kissing disease - from its oral distribution - or as mono in North America and as glandular fever in other English-speaking countries) is an infectious, very widespread viral disease caused by the Epstein-Barr virus, which well over 90% of all adults are exposed to at some point in their life."
