在1989年至2002年期间，共有208，368例实验室确认的志贺氏菌感染报告给疾病控制和预防中心。宋内志贺菌占71.7%，福氏志贺菌占18.4%，鲍氏志贺菌占1.6%，志贺菌占0.7%; 7.6%未报告血清群。全国发病率从1993年的每100 000人7.6例到1999年的每100 000人3.7例不等。发病率为S。boydii，S.和S.在14年的时间里，福氏志贺菌分别下降了81%、83%和64%; sonnei利率仅下降了8%。西部各州（每10万人中有10.0例病例）和1-4岁儿童（每10万人中有20.6例病例）报告的发病率最高。雌雄性S. 20-39岁成年人的宋内氏病发病率比率从1989-1999年的2.3下降到2000-2002年的1.4。大约1%的分离株来自肠外来源; 0.25%来自血液。S.在美国，sonnei仍然是腹泻的重要原因。需要针对高危群体开展预防工作。
During 1989-2002, a total of 208,368 laboratory-confirmed Shigella infections were reported to the Centers for Disease Control and Prevention. Shigella sonnei accounted for 71.7%, Shigella flexneri accounted for 18.4%, Shigella boydii accounted for 1.6%, and Shigella dysenteriae accounted for 0.7% of infections; for 7.6%, no serogroup was reported. National incidence rates ranged from 7.6 cases per 100,000 persons in 1993 to 3.7 cases per 100,000 persons in 1999. Incidence rates for S. boydii, S. dysenteriae, and S. flexneri decreased over the 14-year period by 81%, 83%, and 64%, respectively; S. sonnei rates only decreased by 8%. The highest rates were reported from western states (10.0 cases per 100,000 persons) and among children 1-4 years of age (20.6 cases per 100,000 persons). The female-male S. sonnei incidence rate ratio among 20-39-year-old adults decreased from 2.3 during 1989-1999 to 1.4 during 2000-2002. Approximately 1% of isolates were from extraenteric sources; 0.25% were from blood. S. sonnei remains an important cause of diarrhea in the United States. Prevention efforts that target high-risk groups are needed.
