Needle stick/scratch risk

[summertime2018]

Dear doctors/experts and members,

I have 2 quick straight forward questions free of anxiety and irrational thoughts.

1: how risky is to receive a quick/fast prick by a needle/serynge infected by HIV which was used for drug injection. I insist that it was a quick prick not an injection, but you can see a very tiny red point.

2: how risky is to get scratched by the needle or nails? Can you get HIV or Hep c, a and b?

And last one please, how do I know if the prick is superficiel or deep? As I read that the superficiel is not risky. I have a red tiny point from the prick. Please I wait for your answers.
Thank you all in advance

Unless the needle was full of blood, and had a plunger, and the blood was injected into your bloodstream you had no risk.  You would KNOW if a non-professional (not a healthcare worker) injected a needle into your bloodstream.  You wouldn't be questioning it.  A red tiny point does not indicate that that happened - you'd likely have bruising and swelling at the site.

In any case, if you're concerned, just have a 4th generation test done around a month after the event and get your conclusive result.

Thank you for your quick answer. I would greatly appreciate if you could read my original post where I said my story which is an unlucky and bizarre event and give me an answer because that would give you more information of my exposure. Please!

Thank you
