I can't understand why the front pages of newspapers can cover bird flu and swine flu and everybody is up in arms about that and we still haven't really woken up to the fact that so many women in sub-Saharan Africa - 60 percent of people in - infected with HIV are women.

In fact, a large majority of those have died and of those expected to die of AIDS, as well as of those who are infected with the virus, are in sub-Saharan Africa.

The general population still thinks HIV is something that came in the 80s and went away, or that it only affects the gay population or intravenous drug users.

Sub-Saharan Africa is also home to 400 million of the world's poorest people.

Life expectancy in many parts of Africa can be something around the age of thirty five to thirty eight. I mean you're very fortunate if you live to that age. In fact when I went to Uganda for the first time one of the things that occurred to me was that I saw very few elderly people.

Eighty percent of Americans with HIV do not know they are infected.
