How sick can a person infected with Salmonellosis get?

  • Most infected persons recover without treatment.
  • Some develop severe diarrhea, leading to dehydration and hospitalization for rehydration with intravenous fluids.
  • In some cases, the infection can spread from the intestines to the bloodstream, then to other body sites. In these cases, death can result unless the infected person is treated promptly with antibiotics.
  • A small number of people go on to develop Reiter’s syndrome (pains in joints, irritation of the eyes and painful urination), which can last for months or years and can lead to chronic arthritis.
  • Young children, the elderly and the immunocompromised are the most likely to have severe infections.
