Why was eliezer taken to the infirmary?

Eliezer was taken to the infirmary after he injured his foot, which became infected. He was initially worried about being separated from the rest of the prisoners, but he hoped that receiving medical attention would provide some relief. However, he later learned that staying in the infirmary could also pose risks due to the harsh conditions in the camp. Ultimately, he decided to leave the infirmary to avoid being left behind during the evacuation.
