It turns out the AIDS is a food issue too. As breadwinners (or literally, bread-growers) die of AIDS, Africa falls deeper into hunger and poverty. So AIDS can kill your entire family of starvation.
Since AIDS is just getting rolling in Southern Asia and China, I shudder to think of the implications among the subsistence farmers there. And it's not just farmers -- in any economy, when the people who bring home the bacon stop being able to bring it home, it wreaks havoc.
