This is a timeline of diphtheria, describing major events such as epidemics and medical developments.

Big picture

Year/period Key developments
Ancient times Earliy detailed descriptions of dyphtheria date from ancient Syrian, Egyptian, and Greek writings.[1]
1600s onward Diphtheria infection grows significantly since the 17th century and becomes one of the major causes of death, fuelled by the Industrial Revolution and increasingly crowded urban centers.[2]
1800s Major scientific breakthroughs consolidate the knowledge on diphtheria, which is given its actual name in this century[2]. Bacterium corynebacterium diphtheriae and the diphtheria toxin are discovered.[3][4] Also, the first effective therapeutic serum against diphtheria is developed.[5]
1923 onward After the first diphtheria toxoid vaccine is developed, its subsequent widespread use would lead to a dramatic decrease of diphtheria rates worldwide.[6][7] A more than 90% decrease in number of cases globally results later, between 1980 and 2000.[8]
Recent years Currently most diphtheria cases occur in Sub-Sharan Africa, India, and Indonesia. Globally 4,530 cases were officially reported in 2015, down from nearly 100,000 in 1980.[9][8]

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.[13][14] 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.[2][14]
1613 Epidemic diphtheria epidemic in Spain causes the year to be named "El año de los Garotillos" ("year of strangulations"), due to the many deaths caused by diphtheria suffocation.[15] Spain
1771 Medical development American physician Samuel Bard publishes An Enquiry into the Nature, Cause and Cure, of the Angina Suffocativa, or, Sore Throat Distemper, one of the earliest accurate descriptions of diphtheria as well as one of the first original contributions to pediatrics made by an American.[16] United States
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.[2][17][15][1]
1856 Epidemic San Francisco doctor Victor Fourgeaud describes an epidemic of diphtheria in California.[8] United States
1883 Scientific development Swiss pathologist Edwin Klebs first observes the bacterium corynebacterium diphtheriae in diphtheritic membranes.[14][15]
1884 Scientific development German bacteriologist Friedrich Loeffler first grows corynebacterium diphtheriae in pure culture.[3][6][14][15] Germany
1888 Scientific development French physicians Pierre Paul Émile Roux and Alexandre Yersin, working at Pasteur Institute, discover the diphtheria toxin.[4][15] France
1890 Medical development Japanese bacteriologist Kitasato Shibasaburo, and German physiologist Emil von Behring, successfully immunize guinea pigs with a heat-treated diphtheria toxin, thus creating 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.[5][18][19] Germany (Berlin)
1891 Medical development The first successful therapeutic serum treatment of a child suffering from diphtheria is performed.[5]
1894 Medical development The production and marketing of the diphtheria therapeutic serum begins in Germany.[5] Germany
1894 In Britain, the Burroughs-Wellcome pharmaceutical company begins producing diphtheria anti-toxin.[20] United Kingdom
1894 Medical development American pharmaceutical H. K. Mulford Company of Philadelphia starts production and testing of diphtheria antitoxin in the United States.[21] United States
1895 Publication Hermann M. Biggs publishes The New Treatment of Diphtheria.[22]
1901 Medical development Emil von Behring, for the first time, uses a diphtheria inoculation of bacteria with reduced virulence, hoping with this active immunization to help the body also produce antitoxins.[5] Germany
1902 The Danish Statens Serum Institut (State Serum Institute or SSI) is established to produce diphtheria antitoxin.[20] Denmark
1904 Emil von Behring establishes Behringwerke to produce diphtheria antitoxin.[20] Germany
1905 Medical development Franklin Royer publishes a paper urging timely treatment for diphtheria and adequate doses of antitoxin.[8]
1907 Medical development Experiments start using a toxin–antitoxin (TAT) solution to induce protective immunity against diphtheria, under the assumption that the toxin would stimulate immunity and the antitoxin (antibodies) would counteract the toxicity of the toxin and prevent it from causing disease in the recipient.[1]
1907 Campaign Several cities in Europe and the United States begin immunization programs to administer the toxin–antitoxin (TAT) complex.[1] Europe, United States
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.[5] 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.[23][24] United States
1923 Scientific development French biologist Gaston Ramon, working at Pasteur Institute, develops diphtheria toxoid that could later be used for a toxoid vaccination. The product is licensed; prepared from inactivated bacterial toxin that has lost its toxicity but retaining its antitoxin producing properties. This would be considered the first diphtheria vaccine.[19][8][18] France
1924 Scientific development Gaston Ramon discovers diphtheria and tetanus toxoid, then referred to as anatoxins.[25] France
1926 Medical development British immunologist Alexander Glenny, working at Wellcome Research Laboratories, develops the adjuvant (the substance that enhances the body's immune response to an antigen) for the toxoid vaccine by increasing the effectiveness of diphtheria toxoid when treating it with aluminum salts.[8][19] United Kingdom (London)
1926 Medical development Fluid form of diphtheria toxoid is licensed in the United States.[26] United States
1943 Epidemic Aproximately one million diphtheria cases and 50,000 deaths occur in Europe. A similar number of cases and deaths are believed to occur every year in developing countries at the time.[1]
