Hepatitis simply means a swelling or inflammation of the liver. The type hepatitis that a person contracts (there are 5 common forms) affects their long-term prognosis. The most common and most severe of these different types of liver infection is Hepatitis B, which is caused by the hepatitis B virus (HBV). It is typically...
Hepatitis A, caused by hepatitis A virus, is an acute infectious disease of the liver that is transmitted person to person by ingestion of contaminated food or water or through direct contact with an infectious person. Millions of people are believed to become infected with HAV every year. The incubation period is two to six weeks and on average is 28 days. In less developed countries the HAV is usually contracted in early childhood. Clean water helps to decrease contraction of HAV. In 90%...
Hepatitis C virus (HCV) is an enveloped, positive-sense single-stranded RNA virus of the family Flaviviridae. It consists of a core of genetic material surrounded by an icosahedra protective shell of protein. The genome consists of a single open reading frame that is 9600 nucleotide bases long. HCV replication takes several steps. It primarily replicates in the hepatocytes of the liver. It can also reproduce in peripheral blood mononuclear cells. There is a wide variety of genotypes and...
Hepatitis B virus, HBV, is a part of the Hepadnaviridae family of viruses. HBV can lead to cirrhosis and hepatocellular carcinoma and has been linked to pancreatic cancer. It is classified as a species of the Orthohepadnavirus. Similar viruses have been found worldwide in great apes and monkeys. There a few different genotypes and they all differ by at least 8% of the sequence and have distinct geographical distributions and this has been associated with anthropological history. Type A is...
Hepadnaviruses can cause liver infections in humans and animals. The two recognized genera are Genus Orthohepadnavirus and Genus Avihepadnavirus. It has a small genome of partially double-stranded, partially single stranded circular DNA. It is a group 7 virus that uses an RNA intermediate during replication. Most people who come into contact with the virus are able to clear the infection alone although some cannot and usually progress to fulminant hepatitis. It can cause sever liver...
