DEIR EL-BALAH, Palestinian Territories: Wafaa Elwan’s five-year-old son cannot sleep in the Gaza tent city where she and her seven children shelter, but it is not the guns of war that cause his daily nightmare.
“My son can’t sleep through the night because he can’t stop scratching his body,” the anxious mother said.

The boy has white and red blotches over his feet and legs, and more under his T-shirt. He is one of many Gazans suffering from skin infections ranging from scabies to chicken pox, lice, impetigo and other debilitating rashes.
