Sheikh Adem Hassen, found out he was HIV-positive in 2003.

He started the Baii Association of People Living with HIV and Aids with two other HIV-positive imams. He met Ijigayehu Mekonnen when her son was ill.

She says: "Sheikh Adem collected from the association to provide me with 100 birr ($10, ?5) a month. Now that my son is dead, he has never stopped visiting me."
