No, in other words, the original assumption that one could look at the spread of AIDS in Africa and infer that the same thing would happen in the US was flawed because it was based on a flawed premise; the the conditions under which AIDS transmission was rampant in Africa existed to the same degree in the US. They did and do not.
BECAUSE of said warnings. That's what you consistently fail to realize.
NO. I am not dense, and I am not "failing to realize" anything.
You are failing to understand (or to acknowledge) the point I am making.
STDs were and remain rampant in Africa at levels far above those seen in the US. There was no sudden change in the instances of those STDs in the US. The heterosexual epidemic wasn't
prevented by a change in behavior,
it was never likely given the environment within which AIDS had to work in this country. That's what researchers found when they began to question why the expected explosion in heterosexual cases never materialized.
It is a simple, unfortunate fact that far more people in Africa were infected with STDs which created an opportunity for transmission through open lesions during intercourse. Healthy skin tends to act as a barrier to HIV. Lesions, sores, even abrasions from rough or poorly lubricated intercourse create a dramatic increase in the likelihood that HIV will pass to the partner during sex. This is why it is so easily transmitted by anal intercourse, as said activity almost always results in some tearing of the rectum.
(JER - Yes, that is what I meant by "ideal"... not likely to create a rupture of the skin advantageous to HIV transmittal.)
