A restaurant-related illness outbreak in Oklahoma featuring an uncommon strain of Escherichia coli has expanded to involve at least 231 people, 61 of whom have been hospitalized, Oklahoma health officials announced today.
As described by the OSDH, signs and symptoms of the illness have been similar to those of E coli O157:H7: diarrhea or bloody diarrhea, vomiting, and severe abdominal cramps, usually with no or only mild fever. Bradley called the illness "very similar to [those caused by] other enterohemorrhagic E coli strains." Most of the people infected have had diarrhea lasting a couple of days, but were not sick enough to need medical attention. But despite interviewing more than 1,300 people who ate there, health officials have not yet identified a specific food source for the outbreak.
