Do I need PEP - Medical student going crazy here

[GirlLee]

I am doing a placement overseas (new york), I have come in contact with many HIV patients and accidentally touched a piece of equipment which had fluid (gel and possibly vaginal discharge). This was in a gum clinic and the woman was there for a smear but someone touched the equipment with their gloves during the smear and I brushed my fore-arm on it later. I do not have any bruises or cuts where this happened and from what I have read intact skin is a barrier, however I am very paranoid. I did not bring PEP since we all seem to be told to consider it if going to sub saharan africa etc. This particular patient was HIV +ve.
Would it make a difference if I purchased PEP now (4 days later?) or is my risk really low? Am I worried about nothing? I washed my arm and hands but I am still very worried. I have been told there is no need for PEP but the anxiety is killing me. Any opinions?

Maybe you should choose a different career path if you are going to react this way everytime a situation like this comes along,and I don't mean to put you down but you need to educate yourself about the modes of HIV transmission.

That's what supervisors are for.

I'm just looking for help not to be beat down. As I said, I am a STUDENT, i.e. still learning. Thanks for your help anyway.

How are you being employed and have no idea about blood-borne pathogens?

[GirlLee]

So even though I actually had some gel/fluid on my arm I should be fine?

It's more than just the needle. Anal and vaginal sex has to be unprotected penetrative.

You never had an exposure.
