What are the symptoms of Salmonella and how long do the symptoms last?
Most persons infected with Salmonella develop diarrhea (sometimes bloody), vomiting, fever, and abdominal cramps within12 to 72 hours after infection. Illness ranges from mild to severe. The illness usually lasts 4 to 7 days, and most people recover without treatment. However, infants, the elderly, and people with impaired immune systems are more likely to become severely ill from a Salmonella infection than are others. When severe infection occurs, Salmonella may spread from the intestines to the bloodstream and can even cause death unless properly treated.
