[The omnipresence of helminthiasis]

This article presents a reflexion on the role of helminthic diseases in the world. Emphasis is made on the fact that in spite of its enormous diversity, helminthic parasites have similar epidemiologic behaviours and share high endemicity. Mathematical model design is crucial not only for a better understanding of their transmission mechanisms, but to evaluate different intervention strategies. Nonetheless, control of this serious endemic diseases will be achieved only through the joint effort of governments, funding agencies and researchers.
