Dear doctors . Thank you for your help  

I have occupational exposure and again need you precious knowledge 

Asked him about his relationship: he replied that he has relation with his  girlfriend  and last time was one week ago .I was not able to ask more , I do not think it is allowed to ask about personal issues in details.

Blood work for him came negative 

Hiv ag/ab 

Hbs Ag 

Hcv antibody 

My question about hiv specific ?

What is the risk of getting hiv from such exposure ?

Should I seek PEP or no need ?

It is really difficult time for me .

There is no risk for HIV or hepatitis C from the exposure you describe.  The middle aged man you were assisting sounds to be rather low risk and most importantly, his laboratory tests are negative.  Persons with negative tests do not transmit infection.  I see no need to pursue PEP

I hoe that this assessment is helpful.  EWH

Thank you sir .

So let me if possible ask some more question if possible 

1-he is about 27 years old , looks to have multiple relations . What about incubation period or window period , although his test negative , is not it possible he might be in window period especially last relationship was one week ago.

2- in general what is the risk for needle prick for occupational exposure .

Thank you for ur precious time and valuable information sir.

I'm not sure what "looked to be" means- it sounds rather paranoid.  The so called "window" period is an internet exaggeration which had some small amount of relevance when testing was done with tests that detect antibodies only.  It is not an issue with 4th generation tests of the sort you describe.

2.  About 1% of persons who get stuck with hollow-point needles which have previously been used on persons with untreated HIV become infected.  

Please don't be paranoid.  You are not at risk.  EWH

I really appreciate your kind help .
