needlestick laceration vs sharingneedles

[addihere]

why is it that when IV drug users share needles, there's a 67% chance of transmission of HIV but if a healthcare worker gets a needle stick laceration, it's a low chance of transmission? why is that? and i it true that the smaller the amount of HIV-infected fluid one is exposed to, the lower the chances of getting infected? like a glass full of blood being more of a transmission threat than a drop of blood?

are you saying that a needle with no blood on surface holds n risk? please answer

what if the nurse reused the needle by mistake,to be honest,the needle without any blodd on it,but the inner part of it,i'm not so sure.

negative777 get your d@m facts correct

IV drug abuser always share the needles for injection,the needle stick is not meaning injection,the healthcare worker always use the alcohol or soap to clean,so the chance should be low to 0.3

It's common sense, think about it. IV drug abuser and a heathcare worker are doing two totally different things.
