Document Summary
Humans, apes, and birds serve as natural hosts. There are currently seven species in this family, divided to 2 genera. Its best-known member is the hepatitis b virus. Diseases associated with this family include: liver infections, such as hepatitis, hepatocellular carcinomas (chronic infections), and cirrhosis. Hepatitis b virus is a member of the hepadnavirus family. The life cycle of hepatitis b virus is complex. Hepatitis b is one of a few known non-retroviral viruses which use reverse transcription as a part of its replication process: attachment: The capsid is transported on the microtubules to the nuclear pore: the core proteins dissociate from the partially double stranded viral dna is then made fully double stranded and transformed into covalently closed circular. Signs and symptoms of hepatitis b, ranging from acute symptomatic or asymptomatic chronic liver disease, usually appear about one to four months after you have been infected. In addition, is implicated in primary hepato-cellular carcinoma, induced a cell mediated response.
