ADDIS ABABA, Ethiopia - Solomon Henderson inherited just three things from his birth parents, who left him at an Ethiopian orphanage when he was 1 year old: a picture of Jesus, a plastic crucifix and HIV.

As one of some 14,000 Ethiopian children born with the virus every year, Solomon’s prospects for survival — much less adoption — were grim. But Erin Henderson’s heart stirred when she saw him, and she decided, on the spot, to adopt him.
