[Infectious diarrhea study in Castellón, Spain (EDICS): population incidence of sporadic cases in 2004 and comparison with the year 2000]. / Estudio de la diarrea infecciosa en Castellón (EDICS): incidencia poblacional de casos esporádicos en 2004 y comparación con el año 2000.

BACKGROUND AND OBJECTIVE: Infectious intestinal diseases are highly prevalent, and among them sporadic cases are the most common processes. The aim of this study was to estimate the incidence of sporadic cases diagnosed in a healthcare district of Castellón (Spain) in the year 2004, and to compare them with those of the year 2000. MATERIAL AND METHOD: Based on routine coprocultures and individual demographic data of each patient, we calculated the population rates by age for the more frequent microorganisms, especially detailed for children up to 5 years of age. We report the results of the year 2004, and compare these with the previous study of the year 2000. RESULTS: Campylobacter showed the highest rate (1.01 x 103), followed by Salmonella (0.75), each without significant differences regarding the year 2000. The rate of rotavirus cases (0.65) was smaller than in 2000; and for adenovirus 2004 was an atypical seasonal year. In children younger than 3 years, rates were 26.54; 10.23 and 11.75. As in the previous study, the age-distribution in children < 5 years was very particular. An U inverted shape was seen for Campylobacer, and the rates for rotavirus decreased after the peak observed in the youngest group (< 6 months). Among hospitalized patients rotavirus was the most common and Campylobacter the less common. CONCLUSIONS: The epidemiological traits of the rates by age until the age of five are characteristic for each microorganism, as are the proportions of hospitalization. Rates of Campylobacter and Salmonella in the year 2004 were similar to the year 2000, but a decrease in the rotavirus rates was observed.

Fundamento y objetivo: Las infecciones intestinales son procesos muy frecuentes y la mayor parte de ellas son casos esporádicos. Se pretende estimar su incidencia poblacional en un área de Castellón durante el año 2004 y compararla con la del año 2000. Material y método: A partir de los coprocultivos habituales se calcularon las tasas por edades para los microorganismos más frecuentes, prestando especial atención a los niños menores de 5 años de edad. Se presentan los resultados de 2004 y su comparación con el año 2000. Resultados: Campylobacter presentó las tasas globales más altas (1,01 ƒ 103), seguido de Salmonella (0,75), sin diferencias significativas con el año 2000. Rotavirus, con una tasa de 0,65, disminuyó respecto a 2000 y adenovirus presentó un año atípico. En menores de 3 años las tasas fueron, respectivamente, de 26,54, 10,23 y 11,75. La distribución por edades en menores de 5 años fue muy diferente en cada microorganismo, con forma de U invertida para Campylobacter y perfil decreciente continuo desde el máximo en menores de 6 meses de edad para rotavirus. En hospitalizados destacan las elevadas tasas de Rotavirus, ya desde los menores de 6 meses de edad, y los escasos ingresos por campilobacteriosis. Conclusiones: Los rasgos epidemiológicos que reflejan las distribuciones por edad desde los menores de 6 meses hasta los niños de 5 años son peculiares para cada germen, como lo son las proporciones de hospitalización. Las tasas de Campylobacter y Salmonella fueron estables, pero rotavirus experimentó una disminución de incidencia

[Incidence of sporadic cases of the most frequent intestinal infections in Castellon]. / Incidencia de casos esporádicos de las infecciones intestinales más frecuentes en Castellón.

BACKGROUND: Intestinal infections are highly frequent processes of which solely a part are identified by the epidemiological monitoring systems. This study is aimed at estimating the incidence on the population, by age groups, of the sporadic intestinal infections diagnosed in one healthcare district in Castellón in the year 2000. METHODS: Based on the routine coprocultures, the basic demographic data for each patient was gathered for calculating the diagnosis and hospitalization rates. For children up to five years of age, the per annum rates were calculation for each microorganism. RESULTS: Campylobacter showed the highest rates (114.5 x 10(5)), followed by rotavirus (94.7) and Salmonella (83.0). Rotavirus is predominant among children under one year of age (3,194 x 10(5)), Campylobacter among those 1-4 year-olds, with a maximum of 3,850 x 10(5) among one-year olds, while Salmonella was predominant among all ages starting as of 5 years of age. The rates for cases hospitalized showed a different pattern, rotavirus ranking first (34.9 x 10(5)), Salmonella (21.7 x 10(5)) and Campylobacter (9.9 x 10(5)). With the exception of Salmonella, there were no outbreaks during the period under study. The predominance of Campylobacter was observed at the expense of the cases among children within the 1-4 age range who were not hospitalized. CONCLUSIONS: Up to 4 years of age, the distribution of the germs causing these infections differs every year. A knowledge of the descriptive epidemiology of these infections contributes to the study of the social impact thereof and provides support for delving deeper into some questions that are posed with a view to these diseases and the preventive aspects which can be implemented.

Incidencia de casos esporádicos de las infecciones intestinales más frecuentes en Castellón / Incidence of sporadic cases of the intestinal infections most frequent in Castellón, Spain

Fundamento: Las infecciones intestinales son procesos muy frecuentes de las que solo una parte son identificadas por los sistemas de vigilancia epidemiológica. El objetivo de este estudio es estimar la incidencia poblacional por grupos de edad de las infecciones intestinales esporádicas diagnosticadas en un área sanitaria de Castellón durante el año 2000. Métodos: A partir de los coprocultivos de rutina, se reunieron los datos demográficos básicos de cada enfermo para el cálculo de las tasas de diagnóstico y de hospitalización. En niños de hasta 5 años de edad se calcularon las tasas por año para cada microorganismo. Resultados: Campylobacter presentó las tasas más altas (114,5 por 105), seguido de rotavirus (94,7) y Salmonella (83,0). Rotavirus predomina en menores de 1 año (3.194 x 105), Campylobacter en 14 años, con un máximo de 3.850 por 105 en el segundo año de vida mientras Salmonella predominó en todas las edades a partir de los 5 años. Las tasas de casos hospitalizados tuvieron un patrón diferente, con rotavirus en primer lugar (34,9 por 105), Salmonella (21,7 por 105) y Campylobacter (9,9 por 105). Excepto Salmonella, no hubo brotes en ese periodo El predominio de Campylobacter se observó a expensas de los casos en niños de 1-4 años no hospitalizados. Conclusiones: Hasta los 4 años de edad la distribución de los gérmenes causantes de las infecciones es diferente para cada año. El conocimiento de la epidemiología descriptiva de estas infecciones contribuye al estudio de su impacto social y presta soporte para profundizar en algunas cuestiones que se plantean ante estas enfermedades y los aspectos preventivos que se puedan implementar (AU)
