How did soldiers in World War 1 get dysentery?

Soldiers in World War I contracted dysentery from ingesting contaminated food or water. The trenches in which the soldiers lived and fought were often flooded with water, which became contaminated with human and animal waste. This water was often the only source of drinking water for the soldiers, and they had no way to purify it. In addition, the food that was supplied to the soldiers was often poorly prepared and stored, and was also a source of contamination. The combination of contaminated food and water led to a high incidence of dysentery among soldiers.

Dysentery is a diarrheal disease that can cause severe dehydration, electrolyte imbalances, and malnutrition. It can lead to death if left untreated. The symptoms of dysentery include fever, abdominal pain, and bloody diarrhea. The disease can be treated with antibiotics, but these were not widely available during World War I. As a result, many soldiers who contracted dysentery died from the disease.
