Salmonellosis history and symptoms

Overview
Diarrhea (sometimes bloody), fever, and abdominal cramps. Occasionally can establish localized infection (e.g., in a joint) or enter the blood.

Symptoms
Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours 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. In these patients, the Salmonella infection may spread from the intestines to the blood stream, and then to other body sites and can cause death unless the person is treated promptly with antibiotics. The elderly, infants, and those with impaired immune systems are more likely to have a severe illness.

After bacterial infections, reactive arthritis (aka Reiters Syndrome) can develop. In sickle-cell anemia, osteomyelitis due to Salmonella infection is much more common than in the general population.
