Symptoms
By Mayo Clinic staffSigns and symptoms of shigella infection usually begin a day or two after exposure to shigella. Signs and symptoms may include:
- Diarrhea (often containing blood or mucus)
- Abdominal cramps
- Fever
Although some people have no symptoms after they've been infected with shigella, their feces are still contagious.
When to see a doctor
Contact your doctor or seek urgent care if you or your child has bloody diarrhea or diarrhea severe enough to cause weight loss and dehydration. Also, contact your doctor if you or your child has diarrhea accompanied by a fever of 101 F (38 C) or higher.
