 AB    To investigate the epidemiology of hepatitis B virus (HBV) infection
       among injecting drug users, the authors assessed the prevalence of HBV
       seromarkers among 2,558 injecting drug users recruited through street
       outreach in Baltimore, Maryland, in 1988-1989. Eighty percent of the
       drug users had at least one HBV seromarker. HBV seropositivity was
       associated with increasing age, duration of injecting drug use,
       African-American ethnicity, injecting drugs at least once daily, and
       sharing needles or visiting shooting galleries during the previous 11
       years, but not with high-risk sexual behaviors or a history of sexually
       transmitted disease. This finding is possibly due to the relative
       inefficiency of sexual transmission as compared with parenteral
       transmission in injecting drug users. In addition, HBV seropositivity
       was strongly associated with seropositivity for hepatitis C virus and
       human immunodeficiency virus. The authors conclude that HBV transmission
       among injecting drug users occurs primarily through the sharing of
       contaminated drug injecting equipment rather than through sexual
       relations, and that efforts to prevent HBV infection must target
       injecting drug users early in their injecting careers.
