Investigation of 189 cases of shigellosis reported to the Pima County, Arizona Health Department in 1986 revealed that 23 per cent of cases could be attributed to travel to Mexico, and 10 per cent to day care attendees and their household contacts. No source of infection or high-risk activity could be demonstrated for 43 per cent of the cases. Households in which S. flexneri occurred were more likely to be characterized by crowded living situations and to have no known source of infection.
对1986年向亚利桑那州皮马县卫生部门报告的189例志贺氏菌病病例的调查显示，23%的病例可归因于前往墨西哥旅行，10%可归因于日托参与者及其家庭接触者。43%的病例无法证明感染源或高风险活动。发生弗氏志贺菌感染的家庭更有可能具有居住环境拥挤且无已知感染源的特点。
