title: [The prevalence of hepatitis B virus and delta agent infections among drug abusers in the Valle del Nalón area].
abstract: Hepatitis due to B virus (HBV) and to delta agent are more common in parenteral drug abusers (PDA). These represent an increasingly large group in western societies. To investigate the prevalence of the HBV and delta agent infections in the PDA from our area, serum markers were assessed with enzyme immunoassay techniques in 76 patients. The criterion for the inclusion in the study was to demonstrate the use of the intravenous route as the addiction modality. No particular type of disease was preselected. 65.78% of patients had some positive marker of HBV. 11.84% of the overall population were chronic carriers of HBV. 17.1% were positive for antidelta antibodies. These results suggest a high prevalence of the HBV infection among PDA.
