"Prevalence data from samples of drug injectors are available for 25 European countries over the period 2005–10 (109), and although sampling differences mean this information needs to be carefully interpreted, it does provide a complementary data source. In 17 of these countries, HIV prevalence estimates remained unchanged. In seven (Germany, Spain, Italy, Latvia, Poland, Portugal, Norway), HIV prevalence data showed a decrease. Only one country (Bulgaria) reported increasing HIV prevalence: in the capital city, Sofia, consistent with the increase in cases of newly diagnosed infections. The increases in HIV transmission in Greece and Romania reported in 2011 were not observed in HIV prevalence or case reporting data before 2011. Possible further indications of ongoing HIV transmission were observed among small samples of young injecting drug users (aged under 25) in six countries: prevalence levels above 5 % were recorded in Estonia, France, Latvia, Lithuania and Poland, and increasing prevalence in Bulgaria, over the period 2005–10."
