Ancient Mesopotamia, circa 3000–2000 BCE — Babylonian clay tablets describing jaundice and liver-related illness
Hepatitis, understood historically as inflammation of the liver producing jaundice and systemic illness, was recognized by healers and physicians across ancient civilizations who observed the yellowing of skin and eyes that severe liver disease produced. For most of recorded history, jaundice was treated as a symptom or disease unto itself rather than a manifestation of diverse underlying causes, and remedies drawn from humoral medicine dominated Western practice for nearly two millennia. The unraveling of hepatitis into distinct viral diseases caused by separate pathogens was among the landmark achievements of twentieth-century virology and epidemiology.
Historical Narrative
Among the earliest written references to what historical scholars have interpreted as hepatitis appears in ancient Mesopotamian clay tablets, where Babylonian physicians recorded conditions involving yellow discoloration of the body and prescribed rituals and herbal remedies. The liver held special cosmological and diagnostic significance in Babylonian medicine, used in hepatoscopy — the reading of animal livers for divination — which reflected the organ's perceived centrality to life and health. Egyptian papyri from roughly the same era described jaundice and prescribed remedies including herbal concoctions and dietary modifications.
Hippocratic writers in ancient Greece classified jaundice within the humoral framework, associating it with an excess of yellow bile, one of the four humors whose balance governed health. The Hippocratic corpus described epidemic jaundice in terms that some historians have read as consistent with infectious hepatitis, noting that clusters of jaundice appeared among populations in certain seasons and localities. Galen of Pergamon, the second-century Roman physician whose authority dominated European medicine for more than a millennium, elaborated on hepatic disease within the humoral tradition, describing the liver as the seat of the body's blood production and the origin of nutritive spirit.
During the medieval period, Islamic physicians including Avicenna and Rhazes preserved and extended Greek hepatology, describing jaundice in the Canon of Medicine and other encyclopedic texts. European medieval physicians similarly worked within inherited frameworks, relying on phlebotomy, purgation, and dietary restriction to rebalance the humors believed responsible for liver disease.
A significant empirical shift occurred in the seventeenth and eighteenth centuries as epidemic jaundice attracted closer descriptive attention. Outbreaks among military forces became particularly well documented; the Seven Years' War, the Napoleonic campaigns, and the American Civil War all produced epidemic jaundice among troops, and military surgeons generated detailed observational records. The American physician Theophilus Thompson described what some historians regard as epidemic infectious hepatitis in mid-nineteenth-century accounts, though the concept of viral causation was entirely unavailable to him.
The modern understanding of hepatitis as a viral disease began to emerge in the early twentieth century. Epidemiological investigations in the 1920s and 1930s, particularly in Europe, established that at least some forms of epidemic jaundice spread through contaminated water or food, while other forms appeared to be transmitted through blood or bodily contact. The landmark experimental work of F.O. MacCallum in Britain during and after World War II proposed a distinction between what he termed infectious hepatitis, transmitted through ingestion, and serum hepatitis, transmitted through blood. MacCallum's 1947 proposal of the nomenclature hepatitis A and hepatitis B, though not yet confirmed virologically, gave the field its organizing framework.
The isolation of the hepatitis B surface antigen in 1965 by Baruch Blumberg, who had been investigating genetic variation in blood proteins across global populations, was the decisive virological breakthrough. Blumberg and his colleagues identified what was initially called the Australia antigen in the blood of an Australian Aboriginal man, and subsequent work established its connection to hepatitis B virus. This discovery earned Blumberg the Nobel Prize in Physiology or Medicine in 1976 and opened the path toward understanding, and eventually combating, the global burden of viral hepatitis.
