About shigellosis
Shigellosis is an infectious disease caused by bacteria called Shigella. Most who are infected with Shigella develop diarrhea, fever, and stomach cramps. Some people may have no symptoms. Illness from Shigella usually resolves in 5 to 7 days but recovered individuals may still spread the bacteria.
To prevent shigella infection
General advice for reducing risk of contracting Shigella:
- Wash hands with soap and water after going to the bathroom or changing diapers, and before preparing food or eating.
- Wait at least 24 hours after the last episode of vomiting and/or diarrhea before preparing any food for others.
- Wash cutting boards and counters used for food preparation immediately after use to avoid cross contaminating other foods.
- Avoid sexual activity with those who have diarrhea or who recently (within the past several weeks) recovered from shigellosis.
If you're sick or exposed
People ill with suspected shigellosis should not work in food handling, patient care, or childcare settings, and ill children with suspected shigellosis should not attend daycare until they have seen a healthcare provider and been tested for Shigella infection, even if their illness is mild. People with Shigella infection who work in or attend these sensitive settings must be cleared by Public Health before returning.
