What are diseases you can catch in the trenches?

In trench warfare, soldiers are at risk of several diseases due to unsanitary conditions and close quarters. Common ailments include trench fever, caused by lice; dysentery, often from contaminated water; and typhus, spread by fleas and lice. Additionally, respiratory infections can arise from exposure to the elements and overcrowding. These diseases significantly impacted troop health and morale during conflicts like World War I.
