[Question #11743] Dried blood incident

Hi Doctors:
I browsed some previous questions about dried blood and HIV however one kept nagging me.  Direct contact with the dried blood into your eye.

So I was at a hotel on vacation (Days Inn) and the FIRST night saw something in my thumb nail. My first question was “did I cut myself, was it blood?” I got a toothpick and it came out. Seemed like dirt. 

I then remembered rubbing my eyes and itching my eye with the same thumbnail. 

Thought NOTHING of the thumbnail or scratching/rubbing my eye until 2 days later when I noticed a couple red spots on the comforter that looked like dried blood. One spot looked to even have like a dried clot or crust with it. 

Then I thought back to the dirty thumbnail and how I scratched my eye with it and if that was crusty dried blood in my fingernail?!  Here I am potentially putting dried blood in my eye by scratching it with the thumbnail

Should I be worried about catching HIV from this scenario? 

I never saw fresh blood as far as I know. 

Can you catch HIV by putting dried or crusty blood in a mucus membrane such as eye? 
I was grossed out by the whole thing 

I also have genital herpes but it’s well controlled with medicine and would that make me more susceptible? (I’ve read stories where GH patients have more capability cells to attract HIV)

Welcome back to the Forum.  Congratulations in making it 9 months since your last inquiry.  Bottom line, you cannot get HIV from incidental transfer of blood from a person with HIV to your eye.

Further, this is an entirely theoretical, "what if" situation.
1.  You don't know that what you saw was blood.
2. If it was, you do not know that it was from a person with HIV (statistically unlikely)
3.  HIV is not transferred through transfer of infected material on one's hands
4.  HIV is not transferred in dried material
5.  Your genital herpes is irrelevant.  The possible increased risk for infection relates to the presence of genital herpes at the site of expsoure

I see this as no risk.  No need for concern, no need for testing.  There really should be no need for "but what if" follow ups

Thanks for the congratulations lol
I think a lot of questions stem from inaccurate information. Just read the comments on any article pertaining to STDS.

1) When you mentioned “HIV is not transferred through transfer of infected material on one's hands” you mean if I touch dried blood, it’s on my hands and then touch my eye or something? 

2) I read past responses and you’ve mentioned even dryING blood wouldn’t be a risk?

3) And an associated question: I’ve heard differing views. When is an RPR blood test for syphilis considered conclusive? With a lesion or point of suspected contact?

(I don’t think I have that but just wanted clear answers incase it ever comes up)

1. Correct
2. Correct 
3. Most RPR tests will become positive within 30 days of a potential exposure. Results at six weeks would be conclusive.

Sorry for the delayed response. EWH.
