Leishmaniose visceral no Piauí, 2007-2019: análise ecológica de séries temporais e distribuição espacial de indicadores epidemiológicos e operacionais

Abstract: Objetivo: Analisar a tendência temporal e a distribuição espacial da leishmaniose visceral (LV) no estado do Piauí, Brasil, no período de 2007 a 2019. Métodos: Estudo ecológico de séries temporais. Empregou-se a regressão de Prais-Winsten para analisar a tendência da incidência, letalidade e indicadores operacionais da LV. Resultados: A incidência média de LV no estado foi de 6,03/100 mil habitantes, com tendência crescente na faixa de 40-59 anos (variação percentual anual [VPA] = 3,88 [IC95%0,49;7,40]) e nas … Show more

“…According to Chaves and cols. 2022, the municipalities in the intermediate region of Teresina have an average lethality rate for human VL of 6.02%, ranging from 6.33% in 2007 to 4.14% in 2019, with some isolated cases in the south region of the immediate geographical area of Piripiri [ 55 ]. In our study these regions were predicted as environmentally suitable for both Lu .…”

“…Furthermore, ACL is more prevalent in rural areas of the state, especially in regions of greater social and economic vulnerabilities which in turn have significant underreporting caused by the lack of resources and infrastructure. Overall, these elements generate limitations in epidemiological surveys such as inaccuracy of information, duplicity of notification and/or errors in filling out the forms that make it difficult to find the exact location of the cases [ 55 , 57 ]. In view of this, our results contribute with the knowledge of ACL spatial distribution in the past decade.…”

“…Although neglected, it is considered by the WHO one of the seven global endemics with absolute priority for its mapping [4,5]. Transmission occurs through the bite of the Lutzomyia longipalpis mosquito and controlling this vector is also an essential part of eradicating the disease [6][7][8][9].…”

“…Alguns fatores têm contribuído para a expansão dos casos da leishmaniose visceral no território nacional. Por exemplo: falta de planejamento das cidades, ou seja, construções em locais inadequados, desigualdades socioeconômicas, fatores climáticos e alterações socioambientais, ocasionadas por atitudes antrópicas e migração dos indivíduos, provocando crescente expansão urbana, que, anteriormente, era considerada doença de maior prevalência rural (CHAVES et al, 2022). Em estudos epidemiológicos, a análise espacial é ferramenta poderosa que permite a visualização e a compreensão da distribuição geográfica de doenças.…”
