Hygiene of a soldier in the Civil War?

The camps were filthy, and so were the soldiers. They'd go weeks without washings their clothes or bathing, which led to their clothes, bedding, and bodies becoming infested with lice and fleas. These poor hygiene conditions resulted in a widespread sickness, some soldiers had gotten chronic diarrhea and/or other intestinal disorders, caused by the dirty water, food, or by the germ-carrying insects that scurried the camps.
