TBE surveillance implemented in EU/EFTA countries
Among the 30 EU/EFTA, 20 (67%) had developed surveillance systems for TBE. Comprehensive surveillance exists in 18 countries (60%). In 18 countries (60%) surveillance is implemented at national level, in one country at sub-national level, and in Italy, the system operates at national level but in practice it is only implemented in those regions where the disease is endemic. There is mandatory reporting of TBE cases in 16 countries (53%), voluntary reporting in one country and undefined reporting in three countries.The data is published in the report 'Epidemiological situation of tick-borne encephalitis in the EU and EFTA'. The report was 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 using different case definitions, time scales, and spatial units and do not reflect the complete picture and complexity of the epidemiology of this disease.
