She reports that she was drawing blood from an HIV-positive patient when she stuck herself percutaneously while capping the needle. She immediately washed the puncture wound with betadine. The medical student has a negative HIV serology from the beginning of medical school two years ago. She is monogamous with one male partner and denies any intravenous drug use.
