Hi, i used a needle to pick my teeth and later realised i didnt know where it came from, also it scraped my gum and when i looked at the needle, it had a tiny bit of my blood on it, if the needle had HIV, would i be able to contract the virus this way? Seen as i didnt inject deeply and the needle looked clean, ( the needle didnt have a syringe attached to it ) it was a hollow needle nurses use when doing home visits to collect blood. ( My mother is diabetic) Thankyou for your time
