<jats:p>Data on hospital admissions and laboratory reports were used to estimate the number of hospitalizations of children aged 14 y or less in three geographic regions of Hungary due to group A rotavirus infection. Between January 1993 and December 1996, 9182 hospitalizations for gastroenteritis occurred, of which 1946 (21%) were associated with rotavirus infection. Most (90%) ofthe rotavirus detections were among children aged 4 y or less. By extrapolation, an estimated 5000 rotavirus‐related hospitalizations (8.4/1000 children aged 4 y or less/y) occurred in Hungary during the study period. Marked seasonality of rotavirus infections was observed, with a peak of incidence from December to February. Rotaviruses with “long” RNA electropherotypes predominated each year, but in 1995/1996 20% of electropherotypes in the Budapest area were “short”. Effective surveillance is required for all children hospitalized for diarrhoea as part of a rotavirus immunization program in Hungary. □<jats:italic>Age group, burden, electropherotypes, Hungaiy, region, rotavirus, season</jats:italic></jats:p>
