in chapters 11 and 12 what are the positives and negatives of the refugee camp

They arrive at the refugee camp and Salva is stunned at the sheer number of people there. They are everywhere, in masses and clumps and curled up and milling around. There are men and women and children and old people, but mostly there are boys and young men who ran away to escape fighting in the war.

Salva is organized with children arriving without their family. He feels a stranger again. He looks around at everyone he sees, vowing to find his family if there is even the slightest chance they are still alive. The refugees are reletively safe from the war in the camps but the conditions are unsanitary and filled with disease.
