HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication ; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]
Hepatitis B infection has been preventable by vaccination since 1982. [4] [12] As of 2022, the hepatitis B vaccine is between 98% and 100% effective in preventing infection. [1] The vaccine is administered in several doses; after an initial dose, two or three more vaccine doses are required at a later time for full effect. [1]
Serious side effects from the hepatitis B vaccine are very uncommon. [13] Pain may occur at the site of injection. [13] It is safe for use during pregnancy or while breastfeeding. [13] It has not been linked to Guillain–Barré syndrome. [13] Hepatitis B vaccines are produced with recombinant DNA techniques and contain immunologic adjuvant. [13]
Hepadnaviridae [a] is a family of viruses. [2] Humans, apes, and birds serve as natural hosts. There are currently 18 species in this family, divided among 5 genera. [3] Its best-known member is hepatitis B virus.
Viral hepatitis is liver inflammation due to a viral infection. [1] [2] It may present in acute form as a recent infection with relatively rapid onset, or in chronic form, typically progressing from a long-lasting asymptomatic condition up to a decompensated hepatic disease and hepatocellular carcinoma (HCC).
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.
