In pictures: 'Life Interrupted' by Don McCullin

Antiretroviral drug treatment has brought Charlie back to life. It has made it possible for her to raise her daughter Khanya. Here they sit side by side, reading in Khanya's school. Access to antiretroviral treatment, she says, "means that I am able to work and can continue with my life and look after my children." Khayelitsha township, Cape Town, South Africa, 2004
