Living with Shigellosis

An infection from Shigella bacteria that causes diarrhea, belly pain and fever, and is most common in young children.

Understanding Shigellosis

Shigellosis is a very contagious disease caused by a group of bacteria called Shigella.

Anyone can get it, but young children are most at risk. People get it through contact with an infected person, or through contaminated food, water or surfaces. Symptoms usually begin one to two days after exposure. In healthy people they usually clear in 5 to 7 days, though bowel habits can take months to return to normal. Complications are rare.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Diarrhea, sometimes bloody
  • Belly pain and cramps
  • Fever
  • Nausea and vomiting
  • Dehydration
  • Tiredness and weakness

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
