A previous study indicated that G9P[8] was the most prevalent rotavirus genotype in 22 rural communities of Esmeraldas and an urban hospital in Quito, Ecuador during February 2005- February 2006. The objective of the present study was to characterize the rotavirus genotypes that circulated the same rural areas during the years 2006 - 2007 and the same urban hospital during the year 2007. A total of 990 stool samples were collected in the rural areas, of which 84 (70 from cases and 14 from controls) were rotavirus positive by an immunochromatographic test.Un estudio previo indicó que G9P[8] fue el genotipo de rotavirus más prevalente en 22 comunidades rurales de Esmeraldas y un hospital urbano de Quito, Ecuador durante febrero 2005- febrero 2006.
