One question I have is that in order to get hiv do you need to inject the needle into your veins? or is it just a pinch? I've been reading online and some say it can only be a needle pinch to transmit the virus. Some people in this Site say it has to be injected into your veins in order to transmit it. When getting a tattoo they don't inject a needle into your vein but yet you can still get hIV from it. I just want an answer that's all.. Has nothing to do with my history.
