【 摘 要 】

OBJECTIVE: diarrheas are one of the main causes of morbidity and mortality worldwide. In Chile, diarrhea surveillance is a priority, particularly those caused by rotavitus, in order to find out their epidemiology including circulating serotypes and to promptly detect possible outbreaks. METHODS: a surveillance system was implemented in 8 pediatric hospitals considered as sentinel sites because they cover 62 % of the under 5 years-old population from Metropolitana, Valparaiso and Bio-Bio regions. The standardized case definitions of the World Health Organization were used. The sample analysis was based on ELISA method in the Public Health Institute laboratories. The surveillance system is based on an online electronic form supported on PHP platform, 5.2.6 version, designed to create dynamic and accessible webpages through passwords from the sentinel center terminals of the Regional Ministerial Department of Health and the Public Health Institute; the variables are weekly and monthly introduced. The statistical analysis is carried out through Epinfo-2000. RESULTS: five hundred and ninety nine fecal samples were analyzed in eight months; 164 of them were positive to rotavirus (27.4 %) for a rate of 0.2 per 1000 pop. Fifty six percent were males whereas under 2 years-old group was the most affected (69 %).CONCLUSIONS: the implementation of the sentinel rotavirus surveillance system is a useful tool for the analysis of this disease behavior and for decision-making in the health national programs.
