AIDing in the prevention of AIDS

Demonstrating that taking a daily pill to prevent HIV infection can work in the real world, San Francisco’s largest private health insurer announced yesterday that not one of its 657 clients receiving the drug had become infected over a period of more than two years. That outcome contradicted some critics’ predictions that so-called pre-exposure prophylaxis, or PrEP, would lead to less condom use and more HIV infections. A study published in Clinical Infectious Diseases found that the San Franciscans on PrEP, almost all of whom were gay men, did use fewer condoms — and contracted several other STD's as a result. But none got HIV. Now onto finding a cure for this evil disease.
