Visceral leishmaniasis is a highly lethal zoonosis transmitted by a sandfly. It is caused by a Leishmania protozoan parasite and dogs are the main reservoir. Ceara State is endemic to visceral leishmaniasis and it is considered a high risk transmission area. Temporal and spatial epidemiological studies have been used as tools to analyze the distribution and frequency of human visceral leishmaniasis (HVL). This study aimed to characterize HVL in its epidemiological andtemporal aspects in Ceara State, from 2003 to 2017, as this is a neglected disease and a public health problem. This is an ecological study carried out with HVL confirmed cases in Ceara, using three blocks of years (2003 to 2007, 2008 to 2012 and 2013 to 2017). The disease presented an endemic behavior, affecting mainly male residents in the urban area, especially children under five and young adults between 30 and 49 years old. HVL is recorded in all the municipalities, for more than 10 years, with a growing trend and territorial expansion to the Central and Eastern regions of the State. The results of this study indicated the increase in the incidence and lethality, as well as the expansion of leishmaniasis in Ceara State.
