Why did Anne Frank die of Typhus and not the gas chambers?
Bergen-Belsen was built to hold 10,000 inmates. In December 1944 it held about 15,000. In 1945, as the Soviets advanced in the east, large numbers of prisoners from eastern camps were moved to Bergen-Belsen and other camps more remote from the front. There were 22,000 inmates on 1 February; 41,000 on 1 March; and 60,000 on 15 April. The resulting overcrowding produced a great increase in deaths from malnutrition and disease, particulary Typhus, which apparently swept the camp in early 1945.
