Objectives-To assess spread of bloodborne viruses among prison entrants in Victoria, Australia.
Design-Voluntary confidential testing of all prison entrants for markers of exposure to bloodborne viruses with collection of minimal data on demography and risk factors over 12 months.
Setting-Her Majesty's Prisons, Pentridge and Fairlea, Victoria, Australia.
Subjects-3429 male and 198 female prison entrants (>99% of all prison entrants) ; 344 entered prison and were tested more than once.
Main outcome measures-Prevalence and incidence of antibodies to HIV, hepatitis B, and hepatitis C viruses, and minimal data on risk factors.
1562 (46%) gave a history of use of injected drugs, 1171 (33%) had antibody to hepatitis B core antigen, 1418 (39%) were anti-hepatitis C positive including 914 (64%) of the men who injected drugs, 91 (2.5%) were positive for hepatitis B surface antigen, and 17 (0.47%) were positive for antibody to HIV.
Incidence rates for infection with hepatitis B and C virus were 12.6 and 18.3 per 100 person years, respectively ; in men who injected drugs and were aged less than 30 years (29% of all prison entrants) these were 21 and 41 per 100 person years.
Seroconversion to hepatitis B or C was associated with young age and shorter stay in prison.
Only 5% of those who were not immune to hepatitis B reported hepatitis B immunisation.
