Hemorrhagic enterocolitis caused by Escherichia coli O157:H7 and its complication of hemolytic-uremic syndrome (HUS) are well known from large outbreaks caused by contaminated meats and vegetables. However most cases may be endemic, not related to an outbreak. We identified cases of HUS in Oklahoma, 2002-2005, from the Inpatient Hospital Discharge Database of the Oklahoma State Department of Health (OSDH) and also the cases of HUS and E. coli O157:H7 reported to the OSDH. 110 cases of HUS were identified from the hospital discharge database; only 14 (12.7%) were reported to the OSDH; 122 cases of E. coli O157:H7 infections were reported to the OSDH. Of the 110 cases of HUS, only six (5.5%) patients in two separate clusters may have had a common source of infection. Although interpretation is limited by the few reports to OSDH, our data suggest that E. coli O157:H7 infections and HUS, presumably related to contaminated food, are endemic throughout Oklahoma.
