CDC estimates Salmonella causes about 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths in the United States every year. Food is the source for about 1 million of these illnesses.
- Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 6 hours to 4 days after infection. The illness usually lasts 4 to 7 days, and most persons recover without treatment.
- However, in some persons, the diarrhea may be so severe that the patient needs to be hospitalized.
