OBJECTIVE: To analyze epidemiological and operational indicators, the temporal trend and spatial distribution of visceral leishmaniasis (VL), as well as VL-HIV co-infection in the state of Piauí, Brazil, from 2007 to 2019.
METHODS: This was an ecological time series study. Prais-Winsten regression was used to analyze the trend of VL incidence, case fatality ratio and operational indicators.
RESULTS: Mean VL incidence in the state was 6.03/100,000 inhabitants, with a rising trend in the 40-59 age group [annual percent change (APC) = 3.88; 95%CI 0.49;7.40] and in the regions located in the south of the state: Tabuleiros do Alto Parnaíba (APC = 14.19; 95%CI 3.91;25.50) and Chapada das Mangabeiras (APC = 12.15; 95%CI 6.69;24.96). Mean case fatality ratio was 6.02% and it remained stable. The mean rate of progression to cure was 52.58%, with a falling trend (APC = -5.67; 95%CI -8.05; -3.23).
CONCLUSION: There was rising trend in VL incidence and a falling trend in its cure rate.
