1. INTRODUCTION It is estimated that one-fourth of the world's population is infected with Ancylostoma, particularly in warm humid regions. The importance of this intestinal verminosis as a cause of morbidity varies according to ecological conditions .2 This Conference was convened : (1) to assess the situation with regard to ancylostomiasis in Africa South of the Sahara (its prevalence and gravity) ; (2) to discuss survey methods and study the factors governing the distribution of the disease ; (3) to study the pathogenesis of the disorders it causes ; (4) to discuss the methods to be applied for its treatment and prophylaxis.
