It's very easy to explain.

They died mainly from typhus and typhoid. The Germans had no cure for it, but they tried to stop its spread by delousing clothing and bedding (this is what Zyklon B was really used for). Towards the end of the war, many prisoners became emaciated and died of starvation due to Allied bombings cutting off food supply lines to the camps. Any other questions?
