Resumen:
In order to study seasonality of HUS and VTEC infection in children, 437patients under 6 YEARS (change was made) with acute diarrhoea were studied, eightper cent of whom progressed to HUS. VTEC was found in ten per cent of all the stoolsamples analysed and seasonal occurrence of HUS (p<0.01) was confirmed.Although there was no variation in VTEC frequencies, a significant difference in thedetection of serotype O157:H7 and in the vt profile between cold and warm months(autumn and winter; spring and summer respectively) was established. O157:H7serotype was isolated more frequently during warm months. Moreover, apredominance of vt2 was noted, which was partially replaced by the combination of vt1with vt2 in the cold season. The results of this study indicate the seasonal variation ofthe disease, the presence of serotype O157:H7 and the vt types. They also reinforcethe need to develop prevention programs that include information on the seasonalpattern of the disease and would therefore reduce the impact on public health.Control strategies of the pathogen in cattle, with a seasonal shedding pattern of both E.coli O157:H7 and in vt types in the most risky season of the year, would also be ofbenefit
