RESUMO A leptospirose é relevante para saúde pública pela sua gravidade e modo de disseminação, cuja ocorrência é maior em local com vulnerabilidade socioambiental. No município do Rio de Janeiro, os casos estariam relacionados com sua estrutura social e espacial. Analisou-se a espacialidade da leptospirose nesse município, de 2000 a 2010, por meio de mapas e observações de campo. Resultados sugeriram que os bairros de Barra de Guaratiba, Pedra de Guaratiba e Grumari foram de alto risco - locais com estruturas sanitárias precárias e constantes alagamentos. Ações da Vigilância em Saúde são de grande importância na identificação e intervenção em locais de situações risco à saúde.
Malaria is a major public health problem, and Brazil is the largest contributor in America to the number of cases. In the country, the Amazon concentrates around 99.5% of the cases. This article aims to compare trends in deforestation rate and the parasite index of malaria in the Amazon region between 1996 and 2012. The annual crude rate of deforestation and the Annual Parasite Index (API) of malaria between 1996 and 2012 were estimated. The rate of deforestation has great variability among the states every year, and a similar situation is observed for malaria API over the studied period. There are important variations across the states within this period. The historical series of crude deforestation rate and malaria API have markedly similar trends; with a 1-2 years lag between them, suggesting that the occurrence of fluctuations in deforestation numbers impacts malaria numbers in a period immediately following. The mapping of deforested areas and the analysis of temporal series are therefore useful in the analysis of malaria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
