| giant cell hepatitis | Hepatitis in the neonatal period presumed to be due to a variety of causes, chiefly viral; characterised by direct and indirect bilirubinaemia, hepatocellular degeneration, and appearance of multinucleated giant cells; may be difficult to distinguish from biliary atresia, but is more likely to end with recovery, although cirrhosis may develop. Synonym: giant cell hepatitis. (05 Mar 2000) |

| viral hepatitis | Liver inflammation caused by viruses. Specific hepatitis viruses have been labelled a, b, c, d, e, f, and g. While other viruses can also cause hepatitis, their primary target is not the liver. (12 Dec 1998) |
| viral hepatitis type A | A virus disease with a short incubation period (usually 15 to 50 days), caused by hepatitis A virus, a member of the family Picornaviridae, often transmitted by faecal-oral route; may be inapparent, mild, severe, or occasionally fatal and occurs sporadically or in epidemics, commonly in school-age children and young adults; necrosis of periportal liver cells with lymphocytic and plasma cell infiltration is characteristic and jaundice is a common symptom. Synonym: epidemic hepatitis, hepatitis A, infectious hepatitis, MS-1 hepatitis, short incubation hepatitis, virus A hepatitis. (05 Mar 2000) |
| viral hepatitis type B | A virus disease with a long incubation period (usually 50 to 160 days), caused by hepatitis B virus, a DNA virus and member of the family Hepadnoviridae, usually transmitted by injection of infected blood or blood derivatives or by use of contaminated needles, lancets, or other instruments; clinically and pathologically similar to viral hepatitis type A, but there is no cross-protective immunity; HBsAg is found in the serum and the hepatitis delta virus occurs in some patients. Synonym: hepatitis B, serum hepatitis, transfusion hepatitis, virus B hepatitis. (05 Mar 2000) |
| viral hepatitis type C | Principal cause of non-A, non-B posttransfusion hepatitis caused by an RNA virus that may be related to Flaviviridae family. Synonym: hepatitis C, virus C hepatitis. (05 Mar 2000) |
| viral hepatitis type D | Acute or chronic hepatitis caused by the hepatitis delta virus, a defective RNA virus requiring HBV for replication. The acute type occurs in two forms: 1) coinfection, the simultaneous occurrence of hepatitis B virus and hepatitis delta virus infections, which usually is self-limiting; 2) superinfection, the appearance of hepatitis delta virus infection in a hepatitis B virus carrier, which often leads to chronic hepatitis The chronic type appears to be more severe than other types of viral hepatitis. Synonym: delta hepatitis, hepatitis D. (05 Mar 2000) |
| viral hepatitis type E | Hepatitis caused by a nonenveloped, single-stranded, positive-sense RNA virus 27-34 nm in diameter, unrelated to other hepatitis; it is the principal cause of enterically transmitted, waterborne, epidemic NANB hepatitis occurring primarily in Asia and Africa. Synonym: hepatitis E. (05 Mar 2000) |
| viral hepatitis vaccines | Any vaccine raised against any virus or viral derivative that causes hepatitis. (12 Dec 1998) |
| virus A hepatitis | A virus disease with a short incubation period (usually 15 to 50 days), caused by hepatitis A virus, a member of the family Picornaviridae, often transmitted by faecal-oral route; may be inapparent, mild, severe, or occasionally fatal and occurs sporadically or in epidemics, commonly in school-age children and young adults; necrosis of periportal liver cells with lymphocytic and plasma cell infiltration is characteristic and jaundice is a common symptom. Synonym: epidemic hepatitis, hepatitis A, infectious hepatitis, MS-1 hepatitis, short incubation hepatitis, virus A hepatitis. (05 Mar 2000) |
| virus B hepatitis | A virus disease with a long incubation period (usually 50 to 160 days), caused by hepatitis B virus, a DNA virus and member of the family Hepadnoviridae, usually transmitted by injection of infected blood or blood derivatives or by use of contaminated needles, lancets, or other instruments; clinically and pathologically similar to viral hepatitis type A, but there is no cross-protective immunity; HBsAg is found in the serum and the hepatitis delta virus occurs in some patients. Synonym: hepatitis B, serum hepatitis, transfusion hepatitis, virus B hepatitis. (05 Mar 2000) |
| virus C hepatitis | Principal cause of non-A, non-B posttransfusion hepatitis caused by an RNA virus that may be related to Flaviviridae family. Synonym: hepatitis C, virus C hepatitis. (05 Mar 2000) |
| virus hepatitis | Liver inflammation caused by viruses. Specific hepatitis viruses have been labelled a, b, c, d, e, f, and g. While other viruses can also cause hepatitis, their primary target is not the liver. (12 Dec 1998) |
| virus hepatitis of ducks | A disease of very young ducklings, caused by the duck hepatitis virus (family Hepadnoviridae) and manifested as an acute illness of several days followed by death; the principal lesions are an enlarged necrotic liver filled with ecchymotic haemorrhages. (05 Mar 2000) |
| peliosis hepatitis | A rare condition in which the liver contains very numerous small blood-filled spaces, sometimes lined with endothelium; it may be found incidentally or rupture may cause intraperitoneal haemorrhage. (05 Mar 2000) |
| goose viral hepatitis | An acute, highly fatal disease of goslings and Muscovy ducklings caused by the goose parvovirus and characterised by anorexia, feather loss, and tissue haemorrhages. Synonym: Derzsy's disease. (05 Mar 2000) |
