The extent of epidemiological assessment of TBE cases varies between countries. The data presented here may not therefore be entirely complete and it cannot be excluded that TBE viral infection – with subsequent development of the disease – won’t occur in new areas.

This map is based on documented cases of TBE virus infection as reported by WHO and as published in the Epidemiologisches Bulletin 15/2007 (including Annex) of the RKI.
