Carga de gastroenteritis aguda por rotavirus en escuelas infantiles municipales de Pamplona

Abstract

ObjectivesTo describe the epidemiology of rotavirus acute gastroenteritis (RAGE) in municipal kindergartens in Pamplona during the 2008-09 rotavirus season and hospital admissions due to RAGE in the reference hospital of the health area of Pamplona, Hospital Virgen del Camino. MethodsEpidemiological, observational, prospective study in children aged 0–36 months in municipal kindergartens in Pamplona between October 2008 and March 2009. We recorded all episodes of acute gastroenteritis, studying the presence of and genotypes of rotavirus. During the same period of time, RAGE episodes requiring hospital admission to the Hospital Virgen del Camino were recorded. Hospital admissions due to RAGE from 2000 to 2009 were studied retrospectively. Results319 children aged 4–24 months were included in the observational study, with 249 episodes of acute gastroenteritis being recorded in 163 children. Rotavirus was isolated in 14% of the samples. The most frequent genotype was G1 [P8] (83%). No case of acute gastroenteritis detected in kindergartens led to admission to the Hospital Virgen de Camino. The incidence of hospital admissions due to RAGE during the study period was 2.44/1000 inhabitants, one of the lowest incidences between 2000 and 2009. ConclusionsRotavirus continues to be a frequent agent in episodes of acute gastroenteritis in preschool infants and one of the most important causes of admission due to acute gastroenteritis to a tertiary reference hospital in the months between October and March.
