[Indoor and outdoor nebulization of DDT in the campaign against cutaneous zoonotic leishmaniasis in Algeria].
Zoonotic cutaneous leishmaniasis is expanding in certain regions of Algeria. Since 1981, when the disease was confined to the foci of Biskra and Abadla, it spread to the neighbouring departments (wilayas) and especially to the wilaya of M'sila. The authors report the results of a large campaign against the disease, using DDT house spraying, in this wilaya. The annual incidence, which was 426 cases per 100,000 inhabitants in January 1983, dropped to 17.9 in January 1984. In addition, the efficacy of DDT in the reduction of the sandfly population was tested in two localities. One was sprayed with DDT and the other was not. In the sprayed locality the sandfly population decreased markedly as compared to the control locality. From these observations the authors believe that DDT plays a major role in the interruption of transmission, a hypothesis which needs to be confirmed by case-control studies. They further recommend that an interdisciplinary approach should be developed for the control of cutaneous leishmaniasis.
