Resumo: Few studies have addressed Leptospira seroprevalence and risk factors in urban populations in Colombia. This study aimed to determine seroprevalence and factors associated with Leptospira infection in inhabitants of an urban district of Cali, Colombia. We collected sociodemographic and environmental data, as well as blood samples, from 353 subjects selected through a multistage cluster sampling design. We performed microagglutination test for the eight main Leptospira serogroups circulating in the region, considering a cut-off titer of ≥ 1:100. Most participants were female (226, 64.8%), with mean age 41.4 years, and 89 (32.6%) lived in low-low socioeconomic stratum (SES-1). Overall seroprevalence was 12.2% (95%CI: 10.3%-14.4%). Factors associated with Leptospira infection were SES 1, older age, single marital status, ethnic groups (Afro-Colombian and white/mestizo), school students, absence of toilet, barefoot walking, travel outside Cali in the previous month, and absence of skin and mucous-membrane lesions in the previous month. Our study suggests domestic and peridomiciliary transmission of Leptospira likely related to activities of daily living and inadequate environmental conditions. SES-1 is a major factor associated with Leptospira infection (adjusted OR = 4.08; 95%CI: 2.54-6.53; p < 0.001), suggesting that social and environmental conditions are key elements for endemicity of Leptospira infection in the study area. Epidemiological surveillance, improvement of environmental and sanitary conditions in various SES-1 areas, and community educational campaigns are recommended.

Este estudio tuvo como meta determinar la seroprevalencia y los factores asociados a la infección por Leptospira en una población residente de un distrito urbano de Cali, Colombia. Recogimos datos sociodemográficos y ambientales, así como muestras de sangre, de 353 sujetos seleccionados a través de un diseño de muestreo por conglomerados en etapas múltiples. Se realizó un test de microaglutinación para los ocho serogrupos principales de Leptospira circulando en la región, considerando una zona corte de ≥ 1:100. La mayoría de los participantes fueron mujeres (226, un 64,8%), con un promedio de edad de 41,4 años, con 89 (32,6%) que vivían en condiciones socioeconómicas bajas o muy bajas (SES-1). La seroprevalencia global fue de un 12,2% (IC95%: 10,3%-14,4%). Los factores asociados con la infección por Leptospira fueron SES-1, edad más avanzada, estado civil soltera, grupo étnico (afrocolombiano y blanco/mestizo), estudiantes escolares, ausencia de baño, caminar descalzo, viajar fuera de Cali durante el mes previo al estudio, y ausencia de lesiones en la piel y membranas mucosas durante el mes previo al mismo. Nuestro estudio sugiere que la trasmisión doméstica y peridomiciliaria de la Leptospira está vinculada a actividades de la vida diaria y a condiciones ambientales inadecuadas. SES-1 es un factor importante, asociado a la infección por Leptospira (OR ajustada = 4,08; IC95%: 2,54-6,53; p < 0,001), sugiriendo que las condiciones sociales y ambientales son elementos clave para la endemicidad de la infección por Leptospira en el área de estudio. Se recomienda vigilancia epidemiológica, mejora de las condiciones ambientales y sanitarias en varias áreas SES-1, así como campañas educacionales dirigidas a la comunidad.Poucos estudos trataram da soroprevalência para Leptospira e fatores de risco em populações urbanas da Colômbia. Este estudo teve como objetivo determinar a soroprevalência e fatores associados com a infecção por Leptospira nos habitantes de um distrito urbano de Cali, Colômbia. Os autores coletaram dados sociodemográficos e ambientais, além de amostras de sangue, de 353 indivíduos selecionados através de uma amostragem de aglomerados em múltiplas fases. Foi realizado o teste de microaglutinação para os oitos principais grupos sorológicos da Leptospira circulantes na região, considerando um título de ≥ 1:100. A maioria dos participantes era do sexo feminino (226, 64,8%), com média de idade de 41,4 anos; 89 (32,6%) pertenciam ao estrato socioeconômico mais baixo (SES-1). A soroprevalência global era 12,2% (IC95%: 10,3%-14,4%). Os fatores associados à infecção por Leptospira eram SES-1, idade, estado civil solteiro, grupo étnico (afro-colombiano e branco/mestiço), estudantes, ausência de privada no domicílio, andar descalço, viagem fora de Cali no mês anterior e ausência de lesões mucocutâneas no mês anterior. O estudo sugere a transmissão domiciliar e peridomiciliar da Leptospira, provavelmente associada a atividades cotidianas e condições ambientais adversas. SES-1 é um fator importante associado à infecção com Leptospira (OR ajustado = 4,08; IC95%: 2,54-6,53; p < 0,001), indicando que as condições sociais e ambientais são elementos importantes na endemicidade da leptospirose na área do estudo. Recomendamos a vigilância epidemiológica, melhora das condições ambientais e sanitárias em diversas áreas SES-1 e campanhas educativas comunitárias.Reports in Public HealthCadernos de Saúde Pública2017-06-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6442Reports in Public Health; Vol. 33 No. 5 (2017): MayCadernos de Saúde Pública; v. 33 n. 5 (2017): Maio1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6442/13760https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6442/13761Kevin Escandón-VargasLyda OsorioMiryam Astudillo-Hernándezinfo:eu-repo/semantics/openAccess2024-03-06T15:29:19Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/6442Revistahttps://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:2024-03-06T13:07:22.893402Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
