Although these emotional side effects of war are devastating, so are the diseases that can often be incurable. The seven most common diseases in army camps were typhoid fever, smallpox, measles, diarrhea, pneumonia, malaria, and tuberculosis.
Two-thirds of the soldiers in the Civil War died from disease. Causes for disease were poor hygiene, garbage in the camp, filth from the camp sinks, weather, bad diet, overcrowding, bugs, lack of surgeons, and impure water.
