If the blood in that syringe did indeed contain HIV, the virus would have died within minutes outside of the body.
I would have been terrified though.

Quote:
HIV is a very fragile virus outside of the body. The HIV virus needs the human body as its host. The life span of HIV outside of the body has not been determined. However, we know that HIV needs its host cell (a human), the body temperature, and the chemistry of the blood to survive. Out of the body, HIV is out of its environment. As the blood dries, the HIV will die. In areas like a syringe or on a razor in a medicine cabinet, HIV would probably live longer because of less airflow and it's a more moist temperature controlled area.
Just remember, outside of the body HIV can't survive. In minutes it will die and be harmless, but Universal Precautions should always be used.
