State health officials continued through the weekend to investigate 24 cases of suspected E. coli infections with links to the North Carolina State Fair.

Officials have confirmed that eight of the cases are the O157:H7 strain of E. coli; five people have been hospitalized, three with kidney failure.

Health officials are continuing their detective work to pinpoint the source of the bacteria, by interviewing the affected people as well as fairgoers who did not get sick, according to Julie Henry, a spokeswoman for the Department of Health and Human Services.
