Résumé :
The Unlinked Anonymous Survey of HIV and Hepatitis in Injecting Drug Users (IDUs) aims to measure the changing prevalence of HIV, hepatitis B and hepatitis C in current and former IDUs who are in contact with specialist drug agencies (e.g. needle exchange services and treatment centres). The programme also monitors levels of risk and protective behaviours among IDUs. The data are used to assess and develop appropriate preventative and health education campaigns, evaluate the impact of such interventions, and to assist in the provision of services for IDUs in the United Kingdom.
This revised set of tables presents data from the survey for the period 1990 to 2009. It includes, in addition to data for the whole of England, Wales and Northern Ireland (the areas covered by this survey), data tables for each country and region of England.
Results from the survey show that the prevalence of anti-HBc (a marker of past or current infection with hepatitis B) among participants declined during the early 1990's from 44% in 1990 to 29% in 1995. Prevalence then fluctuated between 25% and 30% until 2006, and then declined to 17% in 2009. The prevalence among the recent initiates to injecting drug use (those who first injected during the preceding three years) is an indicator of recent transmission. The prevalence of anti-HBc among the recent initiates taking part in the survey has fluctuated in recent years indicating no clear trend over time among this group. The survey has monitored, through self-reports, the uptake of the hepatitis B vaccine since 1998. The reported vaccine uptake has increased from 25% in 1998 to 73% in 2009.
These findings suggest that the increase in the uptake of the hepatitis B vaccine might now be having an impact on hepatitis B transmission among IDUs, though this might also reflect the recent decline in injecting equipment sharing. [Extracts]
