[Prisons and HIV. A review of HIV epidemics in 4 prisons in the Oslo area].

It is very likely that the degree of HIV-seropositive prevalence in prisons reflects the HIV epidemic among drug users outside prisons. A thorough epidemiologic survey among prisoners is therefore important. 23% of all known HIV-positive male drug users in Norway have been diagnosed at Oslo Kretsfengsel. The minimum seroprevalence of HIV among the drug users in this prison is 10%. Of the persons detained in Oslo Kretsfengsel who were tested two times or more during their term of imprisonment in 1987 and 1988, none seroconverted.
