Year/period Key developments
19th century Diphtheria infection grows significantly late in the century to become one of the major causes of death, fuelled by the industrial revolution and increasingly crowded urban centers.[1]
1920s The first diphtheria toxoid vaccine is developed, and its subsequent widespread use leads to a dramatic decrease of diphtheria rates worldwide.[2][3]
1990s The vast majority of diphtheria cases occur during an outbreak in the ex-Soviet Union, in which the World Health Organization reports more than 157,000 cases and 5,000 deaths.[2]

Full timeline

Year/period Type of event Event Present time geographical location
5th century BC Scientific development Diphtheria is first described by Greek physician Hippocrates.[4][5] Greece
1600s Scientific development Medical reports of a "deadly" strangulation disease first appear early in the century, and emerges as a greater threat with the growth of urbanizations.[1][5]
1826 Scientific development French physician Pierre Bretonneau gives diphtheria its official name diphtérite, derived from the Greek word for "leather" or "hide", which describes the pseudomembrane in the throat of the victims.[1][6]
1883 Scientific development Swiss pathologist Edwin Klebs first observes the diphtheria bacterium in diphtheritic membranes.[5]
1884 Scientific development German bacteriologist Friedrich Loeffler first grows diphtheria bacterium corynebacterium diphtheriae in pure culture.[7][2][5] Germany
1888 Scientific development French physicians Pierre Paul Émile Roux and Alexandre Yersin, working at Pasteur Institute, discover the diphtheria toxin.[8] France
1890 Medical development German physiologist Emil von Behring develops the first effective therapeutic serum against diphtheria. In 1901 Von Bering would be awarded the first Nobel Prize in Physiology or Medicine for this work.[9][10] Germany
1891 Medical development The first successful therapeutic serum treatment of a child suffering from diphtheria is performed.[9]
1894 Medical development The production and marketing of the diphtheria therapeutic serum begins in Germany.[9] Germany
1901 Medical development Emil von Behring, for the first time, uses a diphtheria innoculation of bacteria with reduced virulence, hoping with this active immunization to help the body also produce antitoxins.[9] Germany
1913 Medical development Emil von Behring publishes his diphtheria protective agent, T.A. (Toxin-Antitoxin), which contains a mixture of diphtheria toxin and therapeutic serum antitoxin. Designed to provide long-term protection, the new drug would further be tested at various clinics and proven to be non-harmful and effective.[9] Germany
1921 Report A high of 206,000 cases of diphtheria and 15,520 deaths (case-fatality ratio of 7.5%) are recorded in the United States.[11][12] United States
1923 Medical development Diphtheria toxoid is licensed; prepared from inactivated bacterial toxin that has lost its toxicity but retains its antitoxin producing properties.[10]
1924 Scientific development French biologist Gaston Ramon, working at Pasteur Institute, discoveres diphtheria and tetanus toxoid, then referred to as anatoxins.[13] France
1947 Medical development Combination diphtheria and tetanus toxoids for pediatric use is first licensed in the United States.[10] United States
1953 Medical development Tetanus and diphtheria toxoids (adult formulation) are first licensed in the United States, after the concentration of diphtheria toxoid is reduced.[10] United States
1964 Policy World Health Organization recommendations for the production and quality control of diphtheria vaccines are first formulated.[14]
1971 Epidemic Seattle experiences the last major diphtheria outbreak in the United States.[15] United States
1974 Program launch Diphtheria toxoid combined with tetanus and pertussis vaccines (DTP) is included in the newly incepted WHO Expanded Programme on Immunization.[14]
1974 Epidemic Diphtheria epidemic breaks out in Lisbon. 500 persons are involved, and about 40 deaths are recorded.[7] Portugal
1982 Epidemic 5 deaths are recorded in Germany during a diphtheria outbreak.[7] Germany
1990-1998 Epidemic Massive diphtheria epidemic breaks out in the ex-Spviet Union. Starting in Russia, the outbreak reaches the Newly Independent States in 1991.[16]Cite error: Closing </ref> missing for <ref> tag
2005 Medical development Sanofi Pasteur licenses Menactra, the first meningococcal polysaccharide (Serogroups A, C, Y and W-135) diphtheria toxoid conjugate vaccine. This would be the first immunogenic meningococcal vaccine indicated for children younger than 2 years of age.[10]
2007 Report 4,190 cases of diphtheria are reported globally.[11]
2011 Medical development United States Food and Drug Administration approves Boostrix (developed by GlaxoSmithKline) to prevent tetanus, diphtheria, and pertussis in older people.[10] United States
