La modificacion del biotopo perihabitacional en la profilaxis de la enfermedad de Chagas

[摘要] In zones endemic for the American trypanosomiasis the modification of the biotopes surrounding human, rural, sylvatic or suburban housing, involves the arrangement of a clean perimetral area completely free of shrubs and chaparral, devoid of dens of wild animals and dwellings of domestic animals, to hinder the persistence of peridomestic foci where the proliferation of Triatomine bugs encourage the reinfestation of the human lodgings. The success of insecticide spraying campaigns, even with simultaneous amelioration of housing, are enhanced by tne modification of the biotopes. A pilot field experience is presented; a 2 year active campaign in a suburban area of Villa Carlos Paz, province Cordoba, Argentina, confirming the methods to eliminate reinfestation of houses from peridomestic sites, in an area of low vector density.
