The report summarises existing information on the occurrence of TBE to obtain a better understanding of the current magnitude of TBE in the European Union (EU) and European Free Trade Association (EFTA) countries. The specific objectives are to characterise the different reporting systems for TBE in EU/EFTA countries; to identify and assess the current epidemiological situation for TBE; identify key risk areas for the disease and provide ECDC with data into its study on burden of disease. The report is a first effort to collect existing data on TBE in EU/EFTA countries. The data, covering the period 2000–2010, were collected from different sources.
