In Liberia's large, deeply religious families, there is usually an aunt somewhere willing to take in a child who has lost a parent. But Ebola, and the fear of contagion and death is now unraveling those bonds. At least 3,700 children across Liberia, Guinea and Sierra Leone have lost one or more parents to Ebola, according to the UN children's agency, and that figure is expected to double by mid-October. Many of these children are left to fend for themselves, and continue to live inside infected houses.
