CDC Broadens Treatment Guidelines

The Centers for Disease Control and Prevention has expanded its guidelines for HIV postexposure prophylaxis to people exposed to the virus in nonoccupational settings, including through sex, injection-drug use, and other high-risk behaviors. PEP has been recommended since 1996 for health care workers exposed to the virus. Studies show a four-week course of anti-HIV drugs started within 72 hours of possible exposure can greatly reduce the risk of HIV infection.
