How to treat children's diarrhea?

Patient's question:

My child is 4 months old. Yesterday, I had a stool test, and the doctor said they have dysentery. Is this disease serious? How is it usually treated?

Doctor's answer:

Principles of Chronic Bacterial Dysentery Treatment: Pathogen Treatment + Symptomatic Supportive Treatment + Concurrent Condition Treatment
Pathogen treatment means using antibiotics, symptomatic treatment means providing hydration for those who are dehydrated, and concurrent conditions refer to existing problems that need to be addressed promptly. You should go to the hospital for intravenous fluids.
Bacterial dysentery is primarily transmitted through the ingestion of water and food contaminated with Shigella bacteria, which infects the human body and causes purulent inflammation of the colon, leading to systemic toxic symptoms. Therefore, the key to preventing bacterial dysentery is to pay attention to dietary hygiene and ensure that the disease is not contracted through the mouth. Acute bacterial dysentery should be diagnosed and treated early.
