Type B viral hepatitis. Recent findings

: The discovery of hepatitis B surface antigen by Blumberg in 1965 offered a specific marker that could readily be employed in the clinical, epidemiological and experimental investigation of type B viral hepatitis. It has since been followed by the continuous gathering of further knowledge concerning this disease. The morphology and immunological and biochemical features of virus B, the epidemiology and prevention of hepatitis B, and marker determination techniques are examined in an overview of the present situation.
