[The average degree of parasitosis, a criterion for evaluation of the geohelminthic contamination of a population, and for application of santiary measures].
The severity of ascaridiasis in a region depends first of all on the degree of pollution by ascaris ova of the environemtn and consquently on the per diem output of ascaris ova in the stools. Therefore, the importance of ascaridiasis as an endemic disease, depends of course upon the number of positive cases, their prevalence, but still more, it depends upon the intensity of the infection of the diseased population (global parasitic discharge). Practically, this concept of global parasitic discharge is expressed by the number of ascaris ova expelled per gram and per day by a sample of the considered population. The mean parasitic discharge is the quotient of the global parasitic discharge through the number of positive cases of the sample. An epidemiological survey and a mass chemotherapy test at La Réunion has showed us that the conept of global parasitic discharge is a more representative reliable and sensitive measuring method than prevalence, to evaluate the gravity of endemic ascaridiasis and its variations.
