The rate of rotavirus infection of both long and short pattern were calculated at 64.1 and 58.6% which 55.9 and 43.1% were positive of long pattern, Monthly distribution of rotavirus infection in Bangkok indicated that the illness tend to cluster in winter season (November through February) and most occurred in January 1995 and November 1996.
