HIV in UK prisons: a review of seroprevalence, transmission and patterns of risk.

Abstract

Prisons contain individuals at high risk of HIV infection, notably through intravenous drug use. For complex political, social and legal reasons penal institutions in the UK are unable to provide condoms and clean needles. The outbreak of HIV and hepatitis B that occurred in a Scottish prison in 1993 focused attention on the potential problems. Debate about the issue is hampered by a lack of useful information. Current data about risk behaviour and seroprevalence is reviewed, and compared with experience in other countries. Injecting drug use in prison appears to be common, and the majority who inject in prison share equipment, which can be used many times. Sexual activity may be a smaller risk factor, but does occur between men in prison. In addition, prisoners appear to have high rates of partner change between sentences. The true prevalence of HIV in UK prisons is difficult to assess, but the available data suggest it is between 0.1 and 4.5%, lower than in Southern Europe and the USA. A window of opportunity still exists to prevent further outbreaks of HIV in UK penal institutions and to maintain these low prevalence rates. Strenuous, and possibly unpalatable measures are needed now.
