Common questions in this guide

What is the best treatment for shigellosis?
Treatment usually focuses on staying safely hydrated. Because of rising antibiotic resistance, your doctor will determine if antibiotics are needed based on local resistance patterns. You should completely avoid anti-diarrheal medications like Imodium, as they can make the infection worse.
What are the possible complications of a Shigella infection?
While many people recover without lasting issues, shigellosis can lead to severe medical complications. Potential complications include Hemolytic Uremic Syndrome (HUS), seizures, and reactive arthritis.
How can I prevent spreading Shigella to my family?
Shigellosis is highly contagious. To protect high-risk individuals like young children and the elderly, practice strict handwashing, do not prepare food for others, and follow your local health department's guidelines for returning to work or school.
Should I take anti-diarrheal medicine like Imodium for shigellosis?
No, you should completely avoid using anti-diarrheal medications like Imodium if you have a Shigella infection. These medications slow down your digestive system, which can keep the bacteria in your body longer and worsen your condition.
When should I go to the emergency room for shigellosis?
You should seek emergency medical care if you are unable to keep enough fluids down to stay hydrated, experience severe complications like seizures, or exhibit specific extreme warning signs discussed with your healthcare provider.
