A Water-borne Outbreak of Diarrhoea

An outbreak of epidemic diarrhoea occurred at an army metrology station in Guiyang City in late April, 1983.There were 111 cases involved and the symptoms were typical.The average attack rate was 31.1% (30.3% for cadres,32.26% for the rank and file, and 30.0% for children). The attack rates were more or less similar among 4 different groups who had their meals either in 3 different canteens or at home.
