An outbreak of cholera due to the Inaba strain was reported in the same institution and season tin 1987. In 1992, the clinical attack rate was 8 per cent of 440 children; there were two deaths. Bath water was contaminated with Vibrio cholerae O1 E1 Tor Ogawa, the same strain as was isolated from the ill children.
