Resumo: | Leptospirosis is an endemic disease in the State of Rio Grande do Sul, Brazil, and presents a broad diversity of exposure routes, reservoirs, etiological agents, and clinical features. The main objective of this work is to identify transmission areas and possible ecological components of leptospirosis transmission. This was accomplished through the aggregation of epidemiological data into spatial units that represent the State's socio-environmental diversity. The 1,274 confirmed leptospirosis cases that occurred in 2001 were georeferenced in the counties of residence. The county maps were overlaid on environmental units characterizing land use, altitude, and river basins. Incidence rates for each environmental class were calculated, along with their statistical significance, through GIS aggregation operations. The highest incidence rates were verified in coastal sedimentary areas with low altitude and predominantly agricultural land use. In these areas, most of the cases were associated with irrigated farming. The results suggest the existence of favorable ecological characteristics for leptospirosis transmission in places involving proliferation of peri-domiciliary rodents and intensive agricultural production. The article discusses the effects of data aggregation into environmental units, as well as strategies to control the endemic in the State. |

O principal objetivo desse trabalho é identificar áreas de maior risco e possíveis componentes ecológicos da transmissão da leptospirose por meio da agregação de dados epidemiológicos em unidades espaciais que representem a diversidade sócio-ambiental do Estado. Os 1.274 casos confirmados de leptospirose ocorridos em 2001 foram georreferenciados por município de residência. Os mapas de municípios foram sobrepostos aos de caracterização de uso do solo, relevo e bacias hidrográficas. Com as operações de SIG, foram calculadas as taxas de incidência para cada categoria e sua significância estatística. As maiores taxas de incidência foram verificadas em áreas sedimentares litorâneas, de baixa altitude e uso do solo predominantemente agrícola. Nessas áreas, a maior parte dos casos está associada à lavoura irrigada. Os resultados sugerem a existência de características ecológicas favoráveis à transmissão da leptospirose em locais de proliferação de roedores sinantrópicos e de produção agrícola intensiva. São discutidos os efeitos da agregação de dados em unidades ambientais na análise de dados epidemiológicos e estratégias de controle da endemia no Estado.Reports in Public HealthCadernos de Saúde Pública2003-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2033Reports in Public Health; Vol. 19 No. 5 (2003): September/OctoberCadernos de Saúde Pública; v. 19 n. 5 (2003): Setembro/Outubro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2033/4053https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2033/4054Barcellos, ChristovamLammerhirt, Célia BeatrizAlmeida, Marco Antonio B. deSantos, Edmilson dosinfo:eu-repo/semantics/openAccess2024-03-06T15:26:47Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/2033Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:02:25.535730Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
