Black squares indicate samples with national coverage; blue triangles indicate 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.
Part of data from Portugal and Hungary include non-IDUs and therefore may underestimate prevalence among IDUs (estimated proportion of non-IDUs in the samples not known).
Data for Spain, Cyprus, Malta, Portugal, Romania, Slovenia and Slovakia are limited to prevalence among IDUs in treatment and may not be representative of prevalence among IDUs who are not in treatment. Data for Luxembourg and part of data for France and Cyprus are based on self-reported test results, which are less reliable than clinically documented tests.
Data for Czech Republic are based on self-reported test results, which are less reliable than clinically documented tests.
Data for Poland, Finland and Estonia are from 2005.
Countries are presented by order of increasing prevalence, based on the average of national data or, if not available, of subnational data.
