Background and Aim: Decisions on public health issues are dependent on reliable epidemiological data. A comprehensive review of the literature was used to gather country-specific data on risk factors, prevalence, number of diagnosed individuals and genotype distribution of the hepatitis C virus (HCV) infection in selected European countries, Canada and Israel. Methodology: Data references were identified through indexed journals and non-indexed sources. In this work, 13 000 articles were reviewed and 860 were selected based on their relevance. Results: Differences in prevalence were explained by local and regional variances in transmission routes or different public health measures. The lowest HCV prevalence ( 0.5%) estimates were from northern European countries and the highest (Z3%) were from Romania and rural areas in Greece, Italy and Russia. The main risk for HCV transmission in countries with wellestablished HCV screening programmes and lower HCV prevalence was injection drug use, which was associated with younger age at the time of infection and a higher infection rate among males.

Recent data suggest that patients with CHC have a higher overall morbidity and mortality (1, 2). A significant portion of liver transplantation in Europe is attributable to cirrhosis and hepatocellular carcinoma because of CHC (3). The socioeconomic impact of hepatitis C virus (HCV) infection is tremendous. The incidence of complications of CHC will not decline over the next 10 years despite improved efficacy of antiviral therapy because most patients with CHC remain undiagnosed (4). Prevention of new infections, HCV screening and early treatment have the potential to reduce the overall morbidity and mortality. However, the cost-effectiveness of HCV screening may depend on the HCV prevalence (5). Decisions on public health issues such as HCV screening and prevention measures are dependent on reliable epidemiological data regarding HCV prevalence and transmission routes. The epidemiological status in Europe is continuously evolving and may vary significantly among the different regions throughout Europe (6). Thus, different countries may need different strategies to reduce the overall burden of HCV infection.Because epidemiological data are the basis for the development of preventive measures, we aimed to systematically identify, review and characterize HCV epidemiology throughout Europe. We included Canada and Israel in our analysis because their healthcare systems and the epidemiological situation are similar to many European countries.

SUMMARY. Morbidity and mortality attributable to chronic hepatitis C virus (HCV) infection are increasing in many countries as the infected population ages. Models were developed for 15 countries to quantify and characterize the viremic population, as well as estimate the number of new infections and HCV related deaths from 2013 to 2030. Expert consensus was used to determine current treatment levels and outcomes in each country. In most countries, viremic prevalence has already peaked. In every country studied, prevalence begins to decline before 2030, when current treatment levels were held constant. In contrast, cases of advanced liver disease and liver related deaths will continue to increase through 2030 in most countries. The current treatment paradigm is inadequate if large reductions in HCV related morbidity and mortality are to be achieved.
