E. coli: Escherichia coli 0157:H7, E. coli 0157:H7 (cont.)

E. coli 0157:H7 Symptoms

The usual initial symptoms include nausea, vomiting, stomach cramps, and diarrhea. The diarrhea is often bloody, and the infected person may have mild fever (about 100 to 101 F or 37.7 to 38 C). The majority of affected individuals (usually children under 5 years of age and the elderly), develop symptoms between 3 and 5 days after ingesting contaminated food or fluid. Some develop symptoms between 1 to 10 days.

The majority of affected individuals resolve the infection without antibiotics in about 5 to 7 days after the onset of symptoms. However, some people (about 10%) develop complications (see complications section listed below) and require hospitalization.
