Big Picture

Year/period Key developments
5th century BC Hepatitis already plagues mankind.[1]
17th-19th century Jaundice epidemics break out in military and civilian populations during wars.[2]
20th century It is first recognized that viruses introduced by fecally contaminated food and water are responsible for hepatitis infection.[3] Multiple scientific developments from the second half of the century establish the current basis of knowledge and treatment of the H viruses.
1960s–1970s Several important milestones in the history of viral hepatitis happen in the 1960s.[4] The hepatitis c virus is identified. Blood tests to detect the hepatitis A and B infection are developed.[5] Modern viral hepatitis research begins with the discovery of Australia antigen.[4]
1980s Hepatitis B vaccine starts implementation worldwide.[6]
1990s–2000s The first Interferon alfa is approved for the treatment for hepatitis C.[7] Multiple drugs are developed for combating hepatitis. The World Hepatitis Alliance is founded.[7]
Recent years There isn’t a vaccine for hepatitis C virus at this time.[8] About 375 million people are infected with the hepatitis B virus. HBV has killed more people than AIDS and is the cause of millions of cases of liver cancer.[9] Most cases of HB are found in the Asia-Pacific region.[6] In 2009, it was estimated that about 1.4 million cases of hepatitis A occurred worldwide.[10] Hepatitis E primarily occurs in South Asia and Africa.[3]


Full timeline

Year/period Hepaitis type Type of event Details Geographical location
400 BC Hepatitis B Medical development The earliest description of epidemic hepatitis, which may or may not have been due to hepatitis B virus, is credited to Greek physician Hippocrates, who describes a condition he called “epidemic jaundice”.[11][8] Greece
741–752 Medical development Pope Zachary quarantines individuals with jaundice to prevent its spread throughout Rome, suggesting an apparent infectious nature of this clinical finding.[4]
1861–1865 Epidemic Large hepatitis epidemic is documented during the American Civil War. 52,000 cases are estimated.[12][11] United States
1870 Epidemic Large hepatitis epidemic breaks out during the Franco–Prussian War.[11]
1865 Scientific development German physician Rudolf Virchow describes a patient with symptoms of epidemic jaundice in whom the lower end of the common bile duct was blocked with a plug of mucus. This would lead to the term “catarrhal jaundice,” because the disease is believed to be caused by catarrh as a result of mucus obstructing the bile duct.[4]
1885 Hepatitis B Scientific development A. Lurman first describes an epidemic of serum hepatitis among 191 German ship workers in Bremen after a smallpox vaccination campaign using human lymph. It is the earliest record of an epidemic caused by hepatitis B virus.[6][11][4] Germany
1908 Scientific development S. McDonald publishes the hypothesis that the infectious jaundice is caused by a virus.[2][4]
1912 Medical development The name Hepatitis is first implemented.[3]
1914–1918 Epidemic Hepatitis epidemic breaks out during World War I.[11]
1942–1945 Hepatitis C Epidemic Approximately 182,383 service members are hospitalized for Hepatitis C during World War II. The disease is contracted in two different ways. An epidemic of hepatitis breaks out among many service members who were vaccinated against yellow fever. The source of the infection is traced to the serum, or clear fluid in the blood, that is used in the vaccine. This form of the disease becomes known as serum hepatitis. A different form of hepatitis, acute hepatitis, is found among soldiers who have received blood transfusions.[8] Europe
1947 Scientific development MacCallum classifies viral hepatitis into two types. Viral hepatitis B is classified as serum hepatitis.[4]
1951 Scientific development Researchers describe a form of chronic hepatitis occurring primarily in young women. Because nearly 15% of these patients have positive lupus erithematosus cell tests, this disorder is first called lupoid hepatitis. By the 1970s its autoimmune origine would be discovered, and today the condition is referred as autoimmune hepatitis.[3]
1953 Medical development Hepatitis becomes a reportable disease.[3]
1957 Scientific development Scientists find that interferon could act as an antiviral drug. The name interferon is given since it could “interfere” with replication or multiplication of the virus.[5]
1963 Hepatitis B Scientific development Blood test to detect hepatitis B infection is developed.[5]
1963–1965 Hepatitis B Scientific development The hepatitis B virus surface antigen HBsAg (also known as Australia antigen) is first identified.[4][11]
1967 Hepatitis B Scientific development American geneticist Baruch Samuel Blumberg and colleagues, while researching genetic links to disease susceptibility, discover the hepatitis B virus. In 1976, Dr. Blumberg would be awarded the Nobel Prize in Medicine for this discovery.[8][13]
1967 Hepatitis B Scientific development Krugman and colleagues recognize the parenterally transmitted nature of hepatitis B, which would lead to the formulation of hygienic measures to prevent the disease.[11]
1968 Hepatitis B Scientific development Prince, Murakami, and Okochi, through independent studies, confirm that the Australia antigen is found specifically in patients who had serum hepatitis (hepatitis B).[4]
1969 Hepatitis B Medical development American physician Baruch Samuel Blumberg and colleagues develop the blood test that is used to detect the hepatitis B virus, and develop the first hepatitis B vaccine.[13]
1970 Hepatitis B Scientific development DS Dane first describes the 42–47 nm double shelled particles (today called Dane particles) as the actual infectious particles, produced by the hepatitis B virus.[11][4]
1973 Hepatitis A Scientific development American researchers Stephen Feinstone, Albert Kapikian and Robert Purcell, working at the National Institutes of Health, identify the virus responsible for hepatitis A. The virus is discovered in fecal samples from prisoner volunteers.[8] United States
1973 Hepatitis A Scientific development Blood test to detect hepatitis A infection is developed.[5]
1974 Hepatitis A Medical development The application of liposomes as a vaccine delivery vehicle is first reported. Since then, liposome-based vaccines against hepatitis A (Epaxal) and influenza (Inflexal V) would be approved for human use.[14]
1975 Unrecognized Scientific development American and British researchers identify a type of hepatitis that doesn’t test positive for the proteins found with hepatitis A virus or hepatitis B virus. Both teams conclude that a previously unrecognized human hepatitis virus is the likely cause.[8]
1977 Hepatitis D Scientific development Rizzetto and coworkers discover the Hepatitis D virus, while trying to find out why some petients with hepatitis B virus infection have more serious disease than others.[15]
1977 Hepatitis B Medical development Dr Chung Young Kim in South Korea develops a hepatitis B vaccine, which becomes known as "Kim's vaccine", using serum from the blood of HBV-infected patients.[16]
1978 Hepatitis E Scientific development Soviet scientist Mikhail Balayan, investigating an outbreak of non-A, non-B hepatitis in Tashkent, discovers the hepatitis E virus, by transmitting the disease into himself by oral administration of pooled stool extracts of 9 patients with non-A and non-B hepatitis.[17][18] Uzbekistan
1981 Hepatitis A Medical development American microbiologist Maurice Hilleman develops the first effective vaccine for Hepatitis A virus.[8] United States
1981 Hepatitis B Medical development The first hepatitis B vaccine is approved in the United States.[19] This “inactivated” type of vaccine involves the collection of blood from hepatitis B virus-infected (HBsAg-positive) donors.[20] The vaccine is 95% effective in preventing infection and the development of chronic disease and liver cancer due to hepatitis B.[21] United States
1986 (May) Hepatitis B Medical development Hepatitis B vaccine Recombivax HB (Merck) is first approved for marketing in West Germany, and two months later by the United States FDA.[22][23] This is the first genetically engineered vaccine[24], a recombinant vaccine resulting from two key discoveries, the expression of proteins in plasmids and the ability to sequence DNA. It is administered by intramuscular injection.[25][26][27] Posology consists in 3 doses (0.5 mL each) at 0, 1, and 6 months for infants, children, and adolescents 0–19 years of age (Pediatric/adolescent formulation), 2 doses (1.0 mL each) at 0 and 4–6 months for adolescentsb 11 through 15 years of age (adult formulation); 3 doses (1.0 mL each) at 0, 1, and 6 months for adults ≥20 years of age (Adult formulation); and 3 doses (1.0 mL each) at 0, 1, and 6 months for predialysis and dialysis patients (dialysis formulation).[28] Germany, United States
1986 Hepatitis A Scientific development Provost et al. successfully prepare a killed hepatitis A vaccine, using virus grown in cell culture that is safe and protective in marmosets. Lewis et al. subsequently report development and early clinical testing of vaccine made from killed attenuated CR326 virus grown and purified from cell cultures of MRC-5 strain human diploid fibroblasts.
