So Sorry if this question is stupid. I currently do physical therapy in a public community center thats not the cleanest sadly, today with my bad luck I got a hair splinter on my foot as I was practicing with the rubber stretching tool. As I was exercising I felt a small burn, I thought it was a paper cut from the rubber but when I got to my car there was a thin black hair like thing in my skin. Sadly I didn't keep the thing to examine and see what it is but it seems like someones hair that happened to be super sharp was on the rubber and I gave myself a hair splinter from that or it might have been junk object .

Is this risky in any way? hiv, hepatitis etc?

if this was magically some sort of a sharp object or needle would there be a risk? 

Whatever it was it wasn't fresh though I don't think. It  was more likely left from someone else's shoe or foot on the rubber.

Thank you for your help and again sorry if this is a dumb question. 

There is a lot of misinformation about risk for acquisition of HIV, hepatitis, or other blood-borne infections as the result of scratches, cuts, scrapes or other forms of trauma. The fact is that to spread these viruses, infected material must be injected deep into tissue as might occur with a hollow bore needle which had been previously used by an infected person.   Unlike hollow bore needles in which the virus can found on the inside of the needle, protected from the environment, cuts and scratches of the sort you describe occur as a result of interactions with solid objects which the virus would not stay on and if present with quickly be inactivated.

The Thera band rubber that the hair/object was on is shared between patients and unfortunately when I focused today, I think the staff forgets to clean them at times. It was also kind of stained/aged from use etc. Even with the sharing considered is it a no risk situation? Its definitely eeky for me and logically I totally understand that it should be a no risk situation but I just want to make sure I don't have to present to a healthcare provider for something like pep etc.

Thank you so much again.

You know what I'm just realizing that it might have been a broken thin suture thread! what do you recommend I do , like you mentioned the risk from inmate object are low but a suture thread which this probably was had direct contact with someone, thankfully I didn't bleed so in one end I want to maybe just wait and get tested rather than take pep and have to keep testing until 12 months. unfortunately all health care providers are closed due to the holidays and I'm trying to avoid the ER due to covid.

There is no medical or scientific reason for testing related to the event you described. If testing would provide you with peace of mind, then of course there is no reason not to do it however, testing for HIV, hepatitis, or other blood-borne pathogens would not be helpful until 4 to 6 weeks following the exposure. Testing before that would be inconclusive. Testing at about four weeks detects nearly all recent infections but not all and the six week benchmark is used for when results would be entirely conclusive. 

I hope the information I provided has been helpful to you. As I suspect you know, we provide up to three responses to each clients questions. This is my third response. Therefore this thread will be closed shortly without further responses.  I really do believe the event you described was a no risk event. I encourage you to try to put it behind you and move forward without continuing concern. EWH
