The epidemiological pattern of hepatitis A, B, and non-A, non-B in Sweden

Abstract

In a clinical series of 148 patients with acute hepatitis, serological analysis of hepatitis A and hepatitis B markers revealed 16% of the cases as hepatitis type non-A, non-b. Hepatitis A was diagnosed in 27% of the patients with drug addicts as the predominating category, while serological evidence of hepatitis B infection was found in 57%, again with drug addicts in the majority. Drug addicts also predominated among the non-A, non-B cases, and possibly this category of patients is today the main reservoir not only of hepatitis B but also of hepatitis A and non-A, non-B.
