Resumo: | This research applies indicators concerning control of the visceral leishmaniasis canine reservoir in the city of Belo Horizonte, Minas Gerais State, Brazil. Data were obtained from the Zoonoses Control Information System (SCZOO) and the Brazilian Information System on Diseases of Notification (SINAN) database. First we analyzed (i) existing associations between canine epidemiological indicators, where the dependent variable was the canine seroprevalence A (2007 to 2013), and the independent variables were, as follows: canine seroprevalence B (2006 to 2012); percentage of positive dogs by ELISA test reagents that were not euthanized; the relationship between the human and canine population; canine population testing coverage by census surveys; and the years of study (2006 to 2013); (ii) then, we examined the association between human visceral leishmaniasis (HVL) cases between 2007 to 2013 and the mentioned variables related to dogs and years. Statistical analysis was done by a generalized linear model (GLM). One unit increases in canine seroprevalence B and canine seroprevalence A were associated to 13% and 12% increases in HVL rates, respectively. The increase in one human/dog ratio unit was associated with a 13% decrease in HVL rates. Canine seroprevalence, human/dog ratio and non-euthanasia of ELISA-reactive dogs in the environment were adequate indicators for analyzing the canine enzootic transmission and the occurrence of HVL cases. |

Los datos fueron obtenidos del Sistema de Control de Zoonosis (SCZOO) y del Sistema Brasileño de Información de Enfermedades de Notificación (SINAN). Comenzamos con el análisis de las asociaciones existentes entre indicadores epidemiológicos caninos, donde la variable dependiente fue la seroprevalencia canina-A (de 2007 a 2013) y la variable independiente fue la seroprevalencia canina-B (de 2006 a 2012); el porcentaje de perros positivos, de acuerdo con el test ELISA, y que no fueron sacrificados; la relación entre las poblaciones humana y canina; la cobertura del test de la población canina, de acuerdo con encuestas censales y los años de estudio (de 2006 a 2013). En seguida, examinamos la asociación entre casos de leishmaniosis visceral humana (LVH) entre 2007 y 2013 y las variables citadas, relacionadas con los perros y los años. El análisis estadístico usó un modelo lineal generalizado (MLG). Los aumentos de una unidad en la seroprevalencia canina-B y seroprevalencia canina-A estuvieron asociados a aumentos de 13% y 12% en las tasas de LVH, respectivamente. Un aumento de una unidad en la razón humano/perro estuvo asociado a una disminución de un 13% en las tasas de LVH. La seroprevalencia canina, la relación humano/perro y la no-eutanasia de perros ELISA-reactivos fueron indicadores adecuados para analizar la transmisión enzoótica canina y la ocurrencia de casos de LVH.O estudo aplica indicadores referentes ao controle do reservatório canino da leishmaniose visceral na cidade de Belo Horizonte, Minas Gerais, Brasil. Os dados foram obtidos do Sistema de Controle de Zoonoses (SCZOO) e do Sistema de Informação de Agravos de Notificação (SINAN). Começamos com a análise das associações existentes entre indicadores epidemiológicos caninos, onde a variável dependente foi a soroprevalência canina-A (de 2007 a 2013) e a variável independente foi a soroprevalência canina-B (de 2006 a 2012); o percentual de cães positivos de acordo com o teste ELISA e que não foram sacrificados; a relação entre as populações humana e canina; a cobertura da testagem da população canina de acordo com inquéritos censitários e os anos de estudo (de 2006 a 2013). Em seguida, examinamos a associação entre casos de leishmaniose visceral humana (LVH) entre 2007 e 2013 e as variáveis citadas relacionadas aos cães e aos anos. A análise estatística usou um modelo linear generalizado (MLG). Os aumentos de uma unidade na soroprevalência canina-B e soroprevalência canina-A estiveram associados a aumentos de 13% e 12% nas taxas de LVH, respectivamente. Um aumento de uma unidade na razão humano/cão esteve associado a uma diminuição de 13% nas taxas de LVH. A soroprevalência canina, a relação humano/cão e a não-eutanásia de cães ELISA-reativos foram indicadores adequados para analisar a transmissão enzoótica canina e a ocorrência de casos de LVH.Reports in Public HealthCadernos de Saúde Pública2020-06-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/7515Reports in Public Health; Vol. 36 No. 6 (2020): JuneCadernos de Saúde Pública; v. 36 n. 6 (2020): Junho1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/7515/16670https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/7515/16671Maria Helena Franco MoraisPaulo Chagastelles SabrozaJosé Eduardo PessanhaAndrea Sobralinfo:eu-repo/semantics/openAccess2024-03-06T15:30:01Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/7515Revistahttps://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:2024-03-06T13:08:38.753714Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
