The U.S. Public Health Service has issued new guidelines on how to manage occupational exposure to HIV. The guidance encourages the immediate use of a postexposure prophylaxis regimen that includes at least three antiretroviral drugs. "Preventing exposures should be the leading strategy to prevent occupational HIV infections. However, when exposure occurs, it should be considered an urgent medical concern and a PEP regimen should be started right away, ideally within hours of the potential exposure," said CDC epidemiologist Dr. David Kuhar, an author of the guidelines.
