You can see these horrifying figures from Africa. These are all countries in southern Africa where between one in seven, and one in three of all adults, are infected with HIV. Now, in the rest of the world, we've got basically nothing going on in the general population — very, very low levels — but we have extraordinarily high levels of HIV in these other populations who are at highest risk: drug injectors, sex workers and gay men. And you'll note, that's the local data from Los Angeles: 25 percent prevalence among gay men. Of course, you can't get HIV just by having unprotected sex. You can only HIV by having unprotected sex with a positive person.
