How is bacterial dysentery transmitted?

Bacterial dysentery is a relatively common intestinal infectious disease in children, caused by Shigella bacteria. Clinically, its primary symptoms include fever, abdominal pain, diarrhea, tenesmus (a constant urge to defecate despite an empty bowel), and passage of loose stools containing mucus and blood. Below, we address how bacterial dysentery spreads.

How Is Bacterial Dysentery Transmitted?

Bacterial dysentery results from infection with Shigella bacteria. These bacteria are excreted in the feces of infected individuals, contaminating food and water sources. Ingestion of such contaminated food or water leads to infection. Additionally, indirect transmission may occur via personal contact, houseflies, cockroaches, and other vectors—ultimately spreading through the fecal-oral route. Mild, atypical cases and chronic, asymptomatic carriers serve as the primary reservoirs for transmission. Following infection, patients commonly experience chills, fever, headache, loss of appetite, abdominal pain, and diarrhea. Prompt medical treatment is strongly recommended.

Initial treatment for bacterial dysentery should involve antibiotics to which the causative strain is sensitive. Cephalosporins—such as ceftriaxone or cefixime—are appropriate options. Alternatively, fluoroquinolones—like levofloxacin—may be used, though these are contraindicated in patients under 18 years of age. Oral berberine may be administered as adjunctive therapy. For patients with fever, antipyretics such as ibuprofen may be prescribed. Aggressive fluid replacement therapy is also essential to maintain electrolyte and hydration balance. Furthermore, if intestinal dysbiosis develops, probiotics may be added to help restore healthy gut flora.

The above outlines the modes of transmission of bacterial dysentery. We hope this information proves helpful.
