HIV Drug Appears to Prevent Infection Even in High-Risk Settings

An HIV drug appears to prevent infection, even in high-risk settings, according to the results of a new study. Despite often not using condoms, none of the 657 patients taking the medication in the study had a new HIV infection during two-and-a-half years of observation by researchers at Kaiser Permanente San Francisco Medical Center. The results were published online Tuesday by the peer-reviewed journal Clinical Infectious Diseases.
