What are the symptoms of E. coli infection?

Symptoms vary but often include stomach cramps, diarrhea (sometimes bloody), vomiting, and mild fever. Symptoms typically appear within four days, though sometimes the "incubation period" can last a week. Most people get better within seven days. But some people develop a very serious problem known as hemolytic uremic syndrome, which can lead to kidney failure. People with HUS require hospitalization.
