Every minute of every day, a child under 15 is infected with HIV - the overwhelming majority of children under 15 who are HIV-positive get infected through their mothers at birth. Without treatment, half of these children die before they reach their second birthday.

I still cannot fathom how difficult it was for the women I met to find out that they were HIV-positive. It is such a courageous undertaking in countries where there is still considerable stigma about the disease. They got tested to ensure that their unborn babies would have a chance of life by being born free of the virus.
