The overlap between HIV treatment and prevention

USA Today (National strategy on AIDS focuses on new infections, testing) does a nice, clear job of reporting on the newly released National HIV/AIDS Strategy, which seeks to lower new HIV infections by 25%, reduce transmission by HIV positive people by 30%, and increase the percentage of HIV positive people who are aware of their infection from 75 to 90 percent.I particularly liked that the article explained the interaction between prevention and treatment, paraphrasing HIV expert  Judy Auerbach:

Auerbach says the line between prevention and treatment "has become blurred" because research shows that people who know they're HIV-positive and get treated are less likely to spread HIV. That's partly because people who know they're infected are more cautious with sexual partners. Evidence also suggests that people who get treated are less infectious even if they do engage in unsafe sex, she says.
