Why was elie hospitalized three days after the liberation?

Elie Wiesel was hospitalized three days after the liberation due to severe food poisoning. After enduring the brutal conditions of the concentration camps, he and other survivors were exposed to food they were not accustomed to, leading to a dangerous reaction. His weakened state from malnutrition and the shock of liberation contributed to his illness. This period of hospitalization highlighted the physical and emotional toll that the Holocaust had taken on survivors.
