World AIDS Day 2010: The Prevention of HIV Transmission in Zimbabwe

Dealing with the Disease
Cliff, 15 (in red sweater), is HIV positive. He lost his mother when he was young, and his grandparents Nicolas and Rita, now in their mid-70s, care for him and six others.

Our grandson Cliff is also HIV positive, but medical staff saw this in time, and he is now on ARV therapy."
