Signs and Symptoms
Not everyone infected with
Shigella bacteria will have symptoms. If symptoms of shigellosis develop, they can include:
Diarrhea, sometimes bloody or lasting more than 3 days
Stomach pain and cramps
A strong, even painful urge to poop
Symptoms usually start within 1–2 days after exposure to
Shigella bacteria from poop and can last about a week. Most people with mild shigellosis usually get better on their own without antibiotic treatment. People who have health conditions that weaken the immune system (such as infection with HIV) or are taking medications that weaken the immune system are more likely to get severely ill and stay sick for a longer time if they have shigellosis. People in these groups should seek medical care if they think they have shigellosis.
If you or a sexual partner have diarrhea (especially bloody diarrhea) lasting more than 3 days
and fever, severe stomach pain, or are dehydrated as a result of diarrhea, talk to a health care provider about shigellosis. A health care provider can test your poop to see if you have shigellosis. If you have severe shigellosis, a health care provider may also test your poop to determine the kind of
Shigella bacteria you’re infected with. This information is needed to better understand which antibiotics will work to treat severe shigellosis if you have it.
