A Study of Ascariasis Eradication by Repeated Mass Treatment

Francisco F. Biagi AND Oscar Rodriguez
Unidad de Patologia, Escuela de Medicina, U. N. A. M., Hospital General, Mexico 7, D. F.

In a village of 529 inhabitants in southeastern Mexico, mass treatments using piperazine in a single-dose, repeated monthly, reduced the ascariasis rate from 28% at the first treatment to no detectable infection at the eighth. Mature worms capable of contributing infectivity to the soil were not seen in post-treatment stools after the sixth month. It is concluded that eradication of human ascariasis by repeated mass treatments can be achieved, at least in a closed population.
