Methods A total of 40 rectal swabs were collected from patients, unaffected students and canteens, and 1 water sample and 1 water sample respectively. The pathogen was tested routinely. Results 18 strains (72.0%) of Shigella sonnei were detected from 25 patients with anal swabs. One strain of Shigella sonnei was detected from the water source and the peripheral water.
