[Variation of helminthiasis incidence in Reunion as a function of different parameters].

Four years after Picot's experiments on parasitic diseases in Réunion Island, and after a large sanitation campaign, the authors valued the effect of this campaign on parasitic incidence. They showed that it had significantly decreased. At the same time, they pointed out the leading part of water quality in parasitic incidence; particularly, they showed that there are twice less Ascaridiasis when water is bacteriologically and chemically safe.
