Today St. Louis Missouri Health officials continue to search for the source of a St. Louis-area E. coli outbreak that has now sickened 22 people. Nine people ranging in age from 4 to 94 have been hospitalized. KMOX Radio reports that the illnesses are not believed to be life-threatening.

While in North Carolina officials are investigating up to 21 possible cases of E. coli affecting people in six counties, with four children still hospitalized because of the ailment. State Epidemiologist Megan Davies said Thursday that nine cases have been confirmed, and 12 more are being evaluated.

Most of the cases come from Wake County, which has seven confirmed and four suspected. Sampson County has six, and there are one each in Durham, Johnston, Franklin and Cleveland counties. Eight of the nine confirmed cases occurred in people who attended the N.C. State Fair, but Davies says investigators don’t know yet how many of the suspected cases were at the event.
