In order to determine the prevalence and incidence of
infections among prisoners, we conducted a prospective study
in a Danish
medium security prison for males. The prisoners were offered
and blood test for hepatitis and human immunodeficiency virus
inclusion as well as at release from prison or end of study.
prisoners available 325 (79%) participated in the initial
survey and for
142 (44%) a follow-up test was available. 43% (140/325) of the
were injecting drug users (IDUs) of whom 64% were positive for
(HBV) and 87% for hepatitis C (Hepatitis C Virus) markers. No cases of HIV
or human T
lymphotropic virus (HTLV) were found. 32% of all prisoners
HBV and/or Hepatitis C Virus by blood contact. 70% of IDUs had shared
equipment, and 60% had injected inside prison. Only 2% of IDUs
vaccinated against HBV. Duration of injecting drug use,
imprisonments, and injecting in prison were independently and
associated with the presence of HBV antibodies among IDUs by
regression analysis. The HBV incidence was 16/100 PY (95% CI:
and the Hepatitis C Virus incidence 25/100 PY (1-140) among injecting drug
We conclude that IDUs in prison have an incidence of hepatitis
B and C 100
times higher than reported in the general Danish population.
They should be
vaccinated against hepatitis B and new initiatives to stop
injecting equipment in and outside prison is urgently needed.
