ABSTRACT

A sentinel-based outpatient and inpatient surveillance for rotavirus infection has been implemented in Chile. Aim: Update the impact of rotavirus infections in Chile. Methods: Ambulatory surveillance is performed in 14 centers from 8 Regions and hospital-based surveillance in 8 hospitals from three Regions (V, VIII and Metropolitan). Results: In 2007, 339 stool samples that represented 9.3 percent of all outpatient cases were studied of which 15 percent were rotavirus positive. A total of 2.074 children younger than 5 years of age were hospitalized representing 9 percent of all hospitalizations for this age group. Rotavirus was detected in 13.6 percent of these cases. Conclusions: In the current epidemiological situation, rotavirus surveillance needs to be sustained with increased efforts to detect cases in order to avoid underreporting. Serotype/genotype surveillance of rotavirus strains needs to be included in the near future.


En Chile, se realiza la vigilancia de gastroenteritis causadas por rotavirus en niños bajo 5 años a través de centros centinelas ambulatorios y hospitalarios. Objetivo: Conocer la epidemiología de las diarreas por rotavirus y evaluar la carga de morbi-mortalidad. Método: La vigilancia ambulatoria se desarrolla en 14 centros de 8 regiones y la vigilancia hospitalaria se lleva a cabo en 8 hospitales pediátricos de las regiones Vª, VIIIªy RM. Resultados: En 2007, 9,3 por ciento de las consultas por diarrea fue estudiada (339), detectándose rotavirus en 15 por ciento de ellas. Se hospitalizaron por diarrea, 2.074 casos, 9 por ciento del total de las hospitalizaciones en este grupo etario. De estas, 13,6 por ciento fueron por rotavirus. Conclusiones: Dada la situación epidemiológica actual, es importante mantener la vigilancia, ampliar la pesquisa de los casos, aplicar el protocolo de vigilancia establecido y determinar el serotipo/genotipo circulante en el país.
