Following the first confirmed imported West Nile virus (WNV) infection in 2011, the number of imported WNV infections to Germany increased in 2012. Two cases of West Nile neuroinvasive disease (WNND) and two cases of West Nile fever (WNF) were reported. The WNND cases were imported from Montenegro and Greece, including the first fatal case for Germany. The WNF cases were imported from Tunisia and Egypt. The cases were unambiguously confirmed according to laboratory criteria of European Centre for Disease Prevention and Control (ECDC). In this report we summarize the clinical and laboratory findings in order to sensitize physicians in Germany for this imported viral disease.
