Figure INF-10

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.

Data for Spain, Italy and Portugal include non-IDUs and therefore may underestimate prevalence among IDUs (proportion of non-IDUs in the samples: Italy 5-10%, Spain and Portugal not known).

Data for Portugal, 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 Norway are from 2004,
