- Abstract: Background:In Brazil, visceral leishmaniasis (VL) is a serious public health problem because of its magnitude,geographical expansion and potential harms caused by illnesses, including death. However, VL is largely ignored indiscussions of tropical disease priorities. Thus, this study aimed to identify factors associated with the expansion ofVL and the dispersion of its vector,Lutzomyia longipalpis, in the municipalities of the State of São Paulo, Brazil.Methods:Information about the date of vector detection and the confirmation of autochthonous VL occurrence inhumans and canines in São Paulo were obtained between 1997 and 2014. Survival curves were calculated by theKaplan-Meier and the Cox multiple regression models was used.Results:The presence of the Marechal Rondon highway showed the highest positive association with vectordispersion and canine and human VL expansion. The monthly maximum and minimum temperature averagesrecorded in the municipalities during the study period were also positively associated with these events. Thepresence of transverse highways was positively associated with the presence of the vector; the border with theState of Mato Grosso do Sul, the presence of a prison, microregion headquarters, and the presence of the TietêRiver were positively associated with the occurrence of canine cases, while only the presence of prison waspositively associated with the occurrence of human cases. The construction of the Bolivia-Brazil gas pipeline wasnot associated with any events.Conclusions:Survival analysis enabled the identification of factors associated with vector dispersion and VLexpansion, thus the results of this study may be useful to the improvement of VL surveillance and control activitiesin the State of São Paulo and throughout Brazil
