I think people have relaxed some since the early years because HIV is no longer the automatic death sentence it was. People look at Magic Johnson for example who has been HIV Positive for over 20 years and they see he's holding up well. That however should not cause people to believe there is a cure!
As for Lburmaster comment she is way off with her statistic that 1 in 3 U.S. Citizens has AIDS. There are over (300 Million people in America) which would mean there would be 100 Million with the disease!
The following informatiion comes from The National Institutes of Health 980 Thousand AIDS cases in America since 1981 and up to 1 Million people may be HIV positive. More focus these days is being placed on other parts of the world such as Africa.
Last but not least we live in a media driven world that is always looking for (the next big thing) whether it's an oil spill, hurricane, earthquake in Hati, Wars...etc Before AIDS came along people were constantly talking about Herpes. Today you hear nothing about it, and yet there is no cure for it either.
Diseases that are contracted via sex will never get the same attention/respect as Breast Cancer, Heart Disease, Diabetes, or other forms of cancer (colon, lung, prostate..etc)
