The virus primarily spreads by the fecal–oral route, [3] and infections often occur in conditions of poor sanitation and overcrowding. Hepatitis A can be transmitted by the parenteral route, but very rarely by blood and blood products.

In the 1960s, the first virus that could cause hepatitis was discovered. This was hepatitis B virus, which was named after the disease it causes. [220] Hepatitis A virus was discovered in 1974. [221] The discovery of hepatitis B virus and the invention of tests to detect it have radically changed many medical, and some cosmetic procedures.

The virus was finally isolated by Max Theiler (1899–1972) in 1932 who went on to develop a successful vaccine. [10] By 1928 enough was known about viruses to enable the publication of Filterable Viruses, a collection of essays covering all known viruses edited by Thomas Milton Rivers (1888–1962).
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer. [31]
Hepatitis D is caused by the hepatitis D virus (HDV), or hepatitis delta virus; it belongs to the genus Deltavirus. HDV is similar to a satellite virus as it can only propagate in the presence of the hepatitis B virus, depending on the helper function of HBV for its replication and expression. It has no independent life cycle, but can survive ...
