Background: Leishmaniosis are a chronic disease complex, which may vary from simple cutaneous lesions to a fatal visceral form, with elevated expansion within the urban centers. Fortaleza is an endemic area for VL and it has been presenting registers of human death in the past decade. The HVL seasonality, the HVL and CVL tendencies have been evaluated, along with the correlation and influence of the seroreactive dogs, of the euthanized dogs, of the abiotic environmental factors and the human and canine population over the coefficient of the HVL incidence, in the Fortaleza town between 2006 and 2012. Materials, Methods & Results: The experimental protocol was approved by the Ethics Committee for the State University of Ceará Animal Use (CEUA/UECE), protocol nº 08622833-1. As a data source for the analysis of HVL and CVL, the monthly quantitative of notified and registered cases in the State of Ceará Health Secretariat (SESA) and in the Fortaleza Zoonosis Control Center (CCZ) was utilized respectively from 2006 to 2012. Fortalezas population estimate during and after the census period, the rainfall average monthly rate (mm), the air relative humidity (%) and the temperature (C), were provided, at the same period, by the Brazilian Institute of Geography and Statistics (IBGE)., The data were analyzed by ANOVA followed by Tukey, linear regression and Spearman correlation test.
