Overview
There are an estimated 400 fatal cases each year; a few cases are complicated by chronic arthritis.Infection is through contaminated food, water, or contact with infected animals.
Natural History
Salmonellosis commonly occurs after 6 to 72 hours afters ingestion of the contaminated food. The inoculum responsible for the disease is often greater 50000 bacteria.[1] Symptoms include acute onset of nausea, vomiting, crampy abdominal pain, and diarrhea, that may be bloody.
Complications
Persons with diarrhea usually recover completely, although it may be several months before their bowel habits are entirely normal. A small number of persons with Salmonella develop pain in their joints, irritation of the eyes, and painful urination. This is called Reiter's syndrome. It can last for months or years, and can lead to chronic arthritis which is difficult to treat. Antibiotic treatment does not make a difference in whether or not the person develops arthritis.
Prognosis
Persons with diarrhea usually recover completely, although it may be several months before their bowel habits are entirely normal. A small number of persons who are infected with Salmonella, will go on to develop pains in their joints, irritation of the eyes, and painful urination. This is called Reiter's syndrome. It can last for months or years, and can lead to chronic arthritis which is difficult to treat. Antibiotic treatment does not make a difference in whether or not the person later develops arthritis.[2]
