Abstract
The hepatitis vi ruses are a diverse collection which, for the most part, have little in common except their name and the disease they cause in a susceptible host. This article outlines what is currently known about each of the hepatitis viruses A - E and summarises the methods which are available for treatment. The most recent developments that have been published in the patent literature during 1994 are also outlined. Emphasis is placed on hepatitis B and C as these are currently perceived to be the largest areas of unmet need for antiviral therapy.
