HIV is transmitted specific ways. The ONLY ways that someone gets HIV is to have unprotected vaginal or anal sex (penetration required with no condom) or sharing IV injectible needles to inject drugs with. Those are the only risks. What you describe is not a risk. Air inactivates the virus. A needle sticking you is not an injection and air is exposed at the end of the sewing needle, therefore, HIV virus would not be active. But the REAL issue is this worry is a classic one for HIV phobics. s this you? Imagining that while you are playing a game that someone came over and stuck you with a sewing needle simply because they touched your back and you're in a sewing shop so they are holding a tool of their work, that they stuck you with it. That's a far fetched tale. If you suffer anxiety, talk to a professional about it. As to this scenario, no, it isn't a risk for HIV and likely no one ever stuck you.
