Does fifty percent of africa have aids?

Does half the country of africa have aids? if so how long before the other half has it? What are some educated predictions of the this? Could a whole continent become exctinct?

Where do you get this stuff from? Africa is not a country. And HIV rates are slowing down in some countries... So no the entire population will not become extinct.
Educated prediction - if people dont find a cure soon you'll have people born who are immune to the disease...
