SOUTH Africa’s young Aids activist, 12-year old Nkosi Johnson, was on Tuesday still in a semi-comatose condition at his adopted mother’s house in Melville, Johannesburg. Gail Johnson said Nkosi had a major seizure again on Friday and spent the night in a local hospital. He was discharged on Saturday. Johnson said his vital signs were stable and his eyes focused. He could, however, not feed himself and was fed fluids and pureed food three times a day through a tube. “After every seizure he becomes a bit less responsive,” Johnson said.
