In Denmark, TBE occurs sporadically, with 5–10 cases reported annually. The island of Bornholm in the Baltic Sea is recognised as an area where TBE is endemic (Map 1).

TBE is not a notifiable disease in Denmark. The occurrence of TBE cases is monitored by the Department of Virology at the National Institute for Health Data and Disease Control (Statens Serum Institut). 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.
