[Indigenous helminthiasis].

Worldwide an estimated 1.5-2 billion people are infested with helminths. Over the last decades, in industrialized countries prevalence rates of human helminthic infections were decreased by means of wastewater and food control. In this article, we review the geographic distributions as well as the impact on the public health system of the most prevalent helminthiases. Special emphasis is given to Echinococcus, Enterobiasis, and Toxocariasis. Intestinal larvae or eggs of helminths can be detected in faeces. Pinworms are collected with a strip of cellophane tape with the sticky side towards the anus. Tissue helminthosis, like Toxocariasis or Trichinosis are associated with eosinophilia and can be diagnosed with sensitive immunological methods or by biopsy. Infection with Echinococcus multilocularis is the most serious parasitic disease in central Europe. Although current therapeutic options are limited, 5 year survival rates were markedly improved by the combination of medical and surgical treatment.
