Echinococcosis in Austria.

In 1982, a research project on the prevalence of human echinococcosis in Austria was started. Within the period from 1982 to 1988, data on 188 patients with cystic (CE) and of 16 patients with alveolar (AE) echinococcosis were obtained. 15 out of 16 AE patients and 79 (= 42%) out of 188 CE patients were Austrian nationals, 1 AE patient was of Swiss nationality, and 94% of the 109 non-Austrian patients came from Mediterranean countries. Cases of (presumably autochthonous) cystic echinococcosis were found in Lower Austria, Vienna, Burgenland, Styria, Upper Austria, Carinthia, Salzburg and Vorarlberg, the eastern part of Austria being the main distribution area. Cases of (certainly autochthonous) alveolar echinococcosis were recorded in the Tyrol, in Carinthia and in Lower Austria. At the time of diagnosis, the average ages of Austrian patients with E. multilocularis (49 years) and with E. granulosus (55 years), respectively were significantly higher than those of foreign CE patients (34 years). The finding concerning the localisation of the infection (78% of E. granulosus cysts and 100% of E. multilocularis lesions were located in the liver) are consistent with previously published reports.
