The European Centre for Disease Prevention and Control (ECDC) has launched a toolkit to support the generation of robust prevalence estimates for hepatitis C virus (HCV) in EU/EEA member states.

Most European countries have a surveillance system for HCV in place that is based on routine notifications. EU/EEA countries are requested to upload surveillance data on HCV into the European Surveillance System (TESSy) on a yearly basis, using the EU case definitions. However, recent surveillance data reported to ECDC indicate that a few countries have experienced difficulties in providing any data on newly diagnosed HCV cases, and that for the majority of countries, completeness is an issue. Efforts to synchronise case definitions and differentiate between acute and chronic cases have been made, but so far have not been completely successful. Due to the differences in surveillance systems and the varying case definitions being used, the possibilities to interpret and compare HCV notification data across countries remain limited.

This toolkit has been developed with the aim of gaining a better understanding of the epidemiology of HCV in EU/EEA countries. A feature of the toolkit is a decision algorithm, which assists member states in selecting the type of survey that should be undertaken and provides modelled estimates of the national burden of HCV in individual countries.
