Anaesthesia and intensive care

The hepatitis C virus (HCV) genome was isolated during the late 1980s using molecular cloning techniques. It is recognized as the cause of most cases of percutaneously transmitted non-A, non-B hepatitis. Prevalence of antibodies to HCV(anti-HCV) in the general Australian population is 0.3%. ⋯ Treatment strategies for HCV, utilizing recombinant interferons, are proving useful in patients with mild to moderate liver disease, but fare less well in patients with cirrhosis. Currently, there is no vaccine for hepatitis C, so pre-exposure prophylaxis is not possible. Equally, no post-exposure intervention, for example with gamma globulin, has been shown to be beneficial, though there may be a role for early interferon therapy.
