During the last ten years Denmark has received an increasing number of immigrants, especially from the Balkans, the Middle East, and Somalia. Some of these may suffer from the zoonoses occurring in their country of origin. But apart from echinococcosis, zoonoses in these immigrants do not seem to pose a quantitatively greater problem than in Danes who have visited these areas. However it is important to have a knowledge of the symptoms and mode of transmission of zoonoses occurring in areas where the immigrants come from.
