I was getting on the subway when a man with a backpack brushed past me. It looked like something sharp was sticking out of his bag—maybe a safety pin, a pen, or even a needle. It poked me around the stomach area.

After checking my skin, I didn’t see any wound on my skin and there was no blood left on my shirt. However, I’m concerned that there might have been a very tiny wound that I just didn’t notice and this may lead to the risk.

Is there any risk of HIV from this kind of situation? I’m worried because I can’t help thinking that he might have done it on purpose maybe he want to spread the HIV (worst case scenario).

Thanks you Dr.
