Over in the Pit (3rd grader sticks 19 with needle...one tests positive for HIV (http://boards.straightdope.com/sdmb/showthread.php?t=314379))they are discussing the hysteria of contracting AIDS from a diabetes test needle. That got me to wondering just how great the likelihood really is of getting infected from an accidental needle puncture, vs, say, unprotected sex with an infected partner. There is one thread that discusses it, (Important Question re: HIV infectability (http://boards.straightdope.com/sdmb/showthread.php?t=56987)) but it's pretty old.

I assume it's one of those probability things where if you get a single HIV virus you have a chance - albeit tiny - of contracting AIDS, if you get two viruses the probability goes up and if you get a whole syringe full of the virus you have a chance - albeit small of NOT contracting AIDS.

Does anyone have any better numbers than this?
