I guess it is all in how figures are applied. How many HIV infected people have died which would also lower the infected rate?

Shikwati: If one were to believe all the horrorifying reports, then all Kenyans should actually be dead by now. But now, tests are being carried out everywhere, and it turns out that the figures were vastly exaggerated. It's not three million Kenyans that are infected. All of the sudden, it's only about one million. Malaria is just as much of a problem, but people rarely talk about that.
SPIEGEL: And why's that?
Shikwati: AIDS is big business, maybe Africa's biggest business. There's nothing else that can generate as much aid money as shocking figures on AIDS. AIDS is a political disease here, and we should be very skeptical.
SPIEGEL: The Americans and Europeans have frozen funds previously pledged to Kenya. The country is too corrupt, they say.
Shikwati: I am afraid, though, that the money will still be transfered before long. After all, it has to go somewhere. Unfortunately, the Europeans' devastating urge to do good can no longer be countered with reason.

In other words, Zimbabweans are dying of starvation, govermnet (in)actions, lack of medical care, or leaving the country, faster than the remaining infected are infecting new cases.
