One of the most intriguing sources of information about the world in general is the CIA World Factbook. Check out a wealth of information on any country in the world - population, political situation, you name it, it's there. One of the population facts available is HIV infection rate. It's interesting to note that the top 11 countries have a 10% infection rate or higher, and oh, by the way, the top 19 countries are all in Africa. Haiti is the unfortunate 20th, after which the next 12 countries are all African too.
The infection rate in Guinea, the 32nd country on the list, is 3.2%, which seems low compared to Swaziland's (#1) rate of 38.8%, but is still brutal compared to the US rate of 0.6% (#71) and the UK's 0.2% (#94). (All out of 169 countries for which data exists). Good old Svalbard brings up the rear with a non-existent 0.0% infection rate.
Like many of Africa's problems, there is great clamoring for "someone" (usually someone else) to do "something" (usually just send money). The problem is that's been tried over and over, and generally (I might even say universally) failed miserably. Really, at some point, African governments and Africans in general are going to have to start resolving their own problems, starting with ceasing to do evil things to other Africans.
