Notes:. Sample size is the number of positive plus negative tests (total valid tests). Prevalence is number positive divided by total valid tests, excluding missing values. Prevalence from sample size under 50 is not reliable. 2. Self-reported test results for HCV may be unreliable. Prevalence is number reporting a positive test result divided by the number reporting a positive or negative result. 3. Saliva tests for hepatitis C antibodies underestimate prevalence. If test sensitivity is known then figures can be adjusted upwards by dividing prevalence by test sensitivity. Test sensitivity is around 70-90% in older studies and may be up to 90-95% in some recent studies. Figures have not been adjusted. 4. Having health problems is one selection criterion for admission to drug treatment in some countries or cities (Greece, Portugal, Rome), due to long waiting lists or special programmes for infected IDUs, this may result in upward bias of prevalence. Prevalence from treatment data should therefore be interpreted in combination with non-treatment data. 5. Data sources with no information on injecting status were excluded as far as possible, as such prevalence can severely underestimate prevalence among injectors in the same source. Some such sources were however included if samples were large or they provided trends over time, in which case it is indicated that injecting status is unknown and prevalence among injectors may be underestimated. * See Box 6 OL: Data sources prevalence (http://annualreport.emcdda.eu.int) for details of sources. =diagnostic testing; =specific prevalence study; SR=prevalence study based on self-reported test results Part of these data were taken from two literature reviews on HCV prevalence in Europe, most figures were subsequently checked by the national focal points.
