Abstract
Objetivo: Investigar un brote de brucelosis declarado en agosto de 2004 en Vélez-Rubio (Almería), para determinar fuente de infección, mecanismo de transmisión y proponer medidas de prevención. Diseño: Estudio descriptivo y de casos-controles apareados (se seleccionaron tres controles por caso). Emplazamiento: Centros de Salud de Vélez-Rubio y Alcalá de Guadaira. Población: Caso sospechoso/probable: persona con clínica compatible y aglutinación a Brucella positiva, diagnosticado entre julio de 2004 y marzo de 2005; caso confirmado: cuando además se identificó agente causal o comprobó seroconversión. Intervenciones: Como fuentes de información se utilizaron fichas de declaración de enfermedad, encuestas epidemiológicas, historias clínicas e información microbiológica. Se calcularon odds ratio (OR) e intervalos de confianza para estudiar relación entre casos, fuente de infección y mecanismos de transmisión. Se utilizó el test de Chi-cuadrado y corrección de Yates. Resultados: Se identificaron 10 casos (9 en Almería y 1 en Sevilla), 8 probables y 2 confirmados; con edades entre 45 y 81 años. Los síntomas se iniciaron entre mayo y septiembre de 2004. El más frecuente fue fiebre (100%). La OR para ingesta de queso fresco sin higienizar fue de 112 (IC 4,48-16968,94), p< 0,001. Se intervino el ganado fuente de infección. Conclusiones: Se confirmó brote de brucelosis interprovincial por el consumo de queso fresco sin higienizar procedente de venta ambulante. Se identificó la fuente de infección y se realizaron actuaciones por parte de Agricultura.
Goal: To study an August 2004 outbreak of brucellosis notified in Velez-Rubio (Almeria) and to determine the source of that infection as well as its transmission mechanisms, in addition to proposing preventive measures. Methodology: Descriptive study and paired case controls (three controls were selected for each case). Setting: Health Centers in de Vélez-Rubio (Almeria) and Alcalá de Guadaira (Seville). Population: Suspected/probable case: a person with compatible clinical symptoms and positive brusella agglutination diagnosed between July 2005 and March 2005. Confirmed case: in addition to identifying the causal agent, laboratory test results resulted in a confirmation. Interventions: Report forms, epidemiological surveys, clinical histories, and laboratory tests were used as sources of data. Odds ratios (OR) and confidence intervals were calculated to study the relationship among cases, sources of infection, and transmission mechanisms. The Chi Square test and Yates correction were employed. Results: 10 cases were identified (9 in Almeria and 1 in Seville), 8 of them pobable and 2 confirmed, in persons between the ages of 45 and 81. The symptoms first appeared between the months of May and September 2005. Fever was the most frequent symptom (100%). The OR for the consumption of fresh, non.-pasteurized cheese was 112 (CI 4,48-16968,94), p< 0,001. Infected animals were intervened. Conclusions: The inter-provincial outbreak of brucellosis was confirmed as stemming from the consumption of non-pasteurized cheese sold on the street. The source of infection was identified and the Department of Agriculture carried out the necessary actions.
