This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Objective. To analyze the temporal trend and describe the spatial distribution of Visceral Leishmaniasis (VL) in Fortaleza from 2007 to 2017. Methods. Ecological study using segmented temporal regression and spatial distribution. Results. Between 2007-2017, 1,660 new cases and 97 deaths were confirmed. The incidence was ascending (Annual Percent Change (APC)=8.7% 95%CI -3.3;34.1), but descending mortality and lethality APC=-25.9 (95%CI -48.5;-10.6) and APC=-33.0 (95%CI -53.7;-17.6), respectively. From 2010-2015 the incidence decreased (APC=-15.8 95%CI -25.1;-4.0), but mortality (APC=18.7 95%CI 9.4;50.6) and lethality (APC=40.1 95%CI 22.5;72.0) had an upward trend. In 2015-2017, decreased incidence (APC=-24.6 95%CI -36.2;-10.3), and mortality (APC=-44.6 95%CI -58.8;-17,6) lethality remained stable (APC=-13.5 95%CI -38.7;3.8). High incidence neighborhoods were clustered in the western region, however, mortality and lethality did not present defined spatial patterns. Conclusion. VL is endemic in Fortaleza, although there has been a decline in the last three years studied.
RESUMO
Objetivo. Analisar a tendência temporal e descrever a distribuição espacial da leishmaniose visceral (LV) em Fortaleza, 2007-2017. Métodos. Estudo ecológico, mediante regressão temporal segmentada e mapeamento temático. Resultados. No período 2007-2017, foram confirmados 1.660 casos novos e 97 óbitos. No período 2007-2010, a incidência foi ascendente (variação percentual anual [Annual Percent Change], APC=8,7% IC95% -3,3;34,1), enquanto a mortalidade (APC=-25,9 IC95% -48,5;-10,6) e a letalidade (APC=-33,0 IC95% -53,7;-17,6), descendentes. No período 2010-2015, a incidência reduziu-se (APC=-15,8 IC95% -25,1;-4,0) mas a mortalidade (APC=18,7 IC95% 9,4;50,6) e a letalidade (APC=40,1 IC95% 22,5;72,0) apresentaram tendência de crescimento. Em 2015-2017, decresceram a incidência (APC=-24,6 IC95% -36,2;-10,3), e a mortalidade (APC=-44,6 IC95% -58,8;-17,6), a letalidade se manteve estável (APC=-13,5 IC95% -38,7;3,8). Houve concentração de bairros com incidência elevada na região oeste da cidade; porém, a mortalidade e a letalidade não apresentaram padrões espaciais definidos. Conclusão. A LV é endêmica em Fortaleza, embora tenha havido declínio no último triênio estudado.
