We have answered the same question for you, a couple of times on this website.
Let me know if we are giving you enough information or if you need something else.
I know it can be really scary when someone is concerned about HIV, sometimes it can be difficult to put it out of you mind.
It is difficult to give an exact number to your answer as there are so many factor, does the person have HIV?, if they have HIV are they on medication? All we can say is that this would not be a good way for passing HIV to you.
The only way to find out is by going for a HIV test. I know this can cause a lot of worry, let us know if we can help with this in anyway.
Sometimes it can be more helpful to come and chat with a nurse on our nurse chat line, or come and chat with one of the nurses in the clinic about your concerns.
