Shigella Infections


Shigella are bacteria that can infect the digestive tract and cause a wide range of symptoms, from good hand washing practices.

Signs and Symptoms

Shigella bacteria produce toxins that can attack the lining of the large intestine, causing swelling, ulcers on the intestinal wall, and bloody diarrhea.

The severity of the diarrhea sets shigellosis apart from regular diarrhea. In kids with shigellosis, the first bowel movement is often large and watery. Later bowel movements may be smaller, but the diarrhea may have blood and mucus in it.

Other symptoms of shigellosis include:

  • abdominal cramps
  • high fever
  • loss of appetite
  • nausea and vomiting
  • painful bowel movements

Diagnosis and Treatment

To confirm the diagnosis of shigellosis, your doctor may take a stool sample from your child to be tested for Shigella bacteria. Blood tests and other tests can also rule out other possible causes of the symptoms, especially if your child has a large amount of blood in the stool.

Some cases of shigellosis require no treatment, but antibiotics often will be given to shorten the illness and to prevent the spread of bacteria to others.

If the doctor prescribes antibiotics, give them as prescribed. Avoid giving your child nonprescription Joel Klein, MD
