Objective: To estimate incidence of shigellosis in the Kaengkhoi district, Saraburi Province, Thailand.

Methods: Population-based surveillance of shigellosis based in treatment centres. The detected rates of treated shigellosis were corrected for the number of cases missed due to the low sensitivity of microbiological culture methods and participants' use of health-care providers not participating in the study.
