Dysentery is an intestinal infection that causes severe diarrhea, often accompanied by blood or mucus in the stool. It is typically caused by bacteria, such as Shigella or Escherichia coli, or parasites like Entamoeba histolytica. Symptoms may include abdominal pain, fever, and dehydration, which can be serious if not treated promptly. The infection is commonly spread through contaminated food or water, making hygiene and sanitation crucial for prevention. Treatment usually involves rehydration and, in some cases, antibiotics. Maintaining clean drinking water and proper sanitation practices can help reduce the risk of dysentery outbreaks.
