Acute sporadic non-A, non-B hepatitis in Greece.

The influence of non-A, non-B (NANB) agent(s) on the aetiology of acute sporadic viral hepatitis and its possible transition to chronic hepatitis were studied. Acute sporadic NANB hepatitis was diagnosed in 134 (13.5%) of the 993 Greek adults who were admitted consecutively to the Western Attica General Hospital from February 1986 to September 1987.
