Doctor's answer:
Dysentery refers to an intestinal infectious disease characterized by symptoms such as abdominal pain, tenesmus, and the passage of red and white purulent blood stools. It is relatively common in children. It is more prevalent during summer and autumn, but it can also be seen in winter and spring. Modern medicine considers this disease to be an acute intestinal infectious disease caused by Shigella bacteria, commonly known as bacterial dysentery. It is primarily transmitted through the contamination of water, food, and hands by patients or carriers of the bacteria. Flies, in their movement between feces and food, also play an important role in spreading dysentery. Individuals with malnutrition, intestinal parasitic infections, or other weakened physical conditions are more susceptible to this disease. Clinically, it can be classified into two types: acute and chronic bacterial dysentery. If the course of the disease exceeds two months, it is diagnosed as chronic bacterial dysentery.
