Shigellosis is a diarrheal disease caused by a group of bacteria called Shigella. Most people get shigellosis after having close contact with an infected person, eating or drinking contaminated food or water, or touching contaminated surfaces and putting their finger in their mouth. Common symptoms include diarrhea, fever, and stomach pain, and symptoms usually last up to 7 days. Shigella germs spread easily from person to person. The best way to prevent this spread is to practice good hygiene, including frequent handwashing.

Don’t Swallow the Water

Shigella germs are spread easily in food and water. Avoid swallowing water from swimming pools, splash pads, ponds, rivers, and lakes. If you are sick (or were recently sick) with shigellosis, help protect others from getting sick by staying out of the water.
