Figure INF-3:  HIV prevalence among injecting drug users – studies with national and sub-national coverage – Part (ii) Young injecting drug users (under age 25), 2003 to 2004

Notes:

Black square = samples with national coverage; blue triangle = samples with subnational (including local or regional) coverage

Differences between countries have to be interpreted with caution owing to different types of settings and/or study methods; national sampling strategies vary and some sample sizes are small.

Data for Czech Republic include non-IDUs and therefore may underestimate prevalence among IDUs (estimated proportion of non-IDUs in the samples not known).

Data for Czech Republic, Spain, Luxembourg and Slovakia are limited to prevalence among IDUs in treatment and may not be representative of prevalence among IDUs who are not in treatment. In addition, data may not be representative for people who are in treatment - this is known to be the case for Belgium.

Data for Czech Republic, France and Luxembourg are based on self-reported test results, which are less reliable than clinically documented tests. Data for Estonia is from 2005 (see sources).
