It is caused by the protozoa Leishmania chagasi, being transmitted for vector, the phlebotomies, Lutzomyia longipalpis. In virtue of the expansion of the illness in Rio Grande do Norte, it is necessary to evaluate the determinative ambient factors in the proliferation of the vector for better control of the illness. The variable rainfall and the social variables had been analyzed using space regression with two models and the ambient variable of ZANE and the variables analyzed in 205 houses in the cities of Natal, Extremoz, N?sia Floresta, S?o Gon?alo do Amarante, S?o Jose do Mipibu, Parnamirim and Maca?ba the Person and ML Chi-square were used . The analyses had shown that high rainfall, plain relief, the forest, the humid tropical climate the activities of production culture of sugar cane and fruit culture and the presence of bovines increase the risk of the LV. The work showed that it has space aggregation and that ambient factors influence in the LV in the State / A Leishmaniose Visceral (LV) ? uma doen?a end?mica em algumas regi?es do Brasil causada pelo protozo?rio Leishmania chagasi, sendo transmitida por vetor, o flebotom?neo, Lutzomyia longipalpis. Em virtude da expans?o da doen?a no Rio Grande do Norte, ? necess?rio avaliar os fatores ambientais determinantes na prolifera??o do vetor para melhor controle. Foram analisadas as vari?veis pluviom?tricas e sociais utilizando a regress?o espacial com dois modelos. Para as vari?veis ambientais do Zoneamento Agroecol?gico do Nordeste e as analisadas nos munic?pios de Natal, Extremoz, N?sia Floresta, S?o Gon?alo do Amarante, S?o Jos? do Mipibu, Parnamirim e Maca?ba, onde foram georeferenciadas 205 casas, utilizando-se o coeficiente de Pearson e tamb?m o qui-quadrado para as primeiras. Os resultados mostraram que alta pluviosidade, relevo plano, a presen?a de floresta, o clima tropical ?mido as atividades de produ??o cultivo de cana de a??car e fruticultura e a presen?a de bovinos aumentam o risco da LV. Foi confirmada que h? agrega??o espacial e que fatores ambientais influenciam na LV no Estado
