Dasher shares a tent in Lebanon’s Bekaa Valley with nine family members, all of them refugees from the Syrian civil war. Around 500 people live in the informal camp. The next tent over is just 5 feet away, a foot or so short of what’s recommended by public health experts. They have sheets of tarpaulin and plastic that make the walls between them, but so much as stepping out of the tent puts them at unadvisable risk. The drum that feeds their tents running water is shared with a neighboring family, and sometimes it runs out. Instead of the frequent hand-washing being recommended globally, Dasher and his family are wiping their hands with alcohol and cleaning with chlorine.
