How is dysentery caused?

Bacillary dysentery is mainly caused by infection with Shigella, an intestinal infectious disease transmitted via the fecal-oral route. The causes of dysentery include: 1. Unhygienic eating habits—Shigella can survive on contaminated food and water sources, so consuming contaminated food is a significant cause of dysentery; 2. Weakened immunity—as the body's immune system weakens, even a small number of Shigella bacteria may cause disease; 3. Poor living and environmental hygiene—for example, increased fly populations may carry Shigella and contaminate food and daily necessities, thus worsening the condition; 4. Abdominal chilling, indigestion, and infections with other bacteria may also lead to dysentery. To prevent dysentery, it is recommended to maintain food hygiene, strengthen immunity, and preserve a healthy living environment.
