[Infectious diseases in migrants].

The current influx of refugees and the high rate of immigration increase the prevalence and impact of infectious diseases in Europe. Infections may be detected at first contact, as a result of systematic screening or as part of general medical care. Diagnosis and treatment require special expertise and, in some cases, special precautions. The spectrum of imported infections is determined by the countries of origins of the migrants and the circumstances associated with their escape to Germany. In this article, diagnosis and treatment of the most important infectious diseases will be presented. As far as infectious diseases are concerned, refugees and migrants are not a threat to the host population, but instead have to be perceived and cared for as a highly vulnerable group.
