There are theoretical risks of transmission of blood borne infections like HIV, hepatitis B, or hepatitis C during athletic events that could involve blood exposure. However, it occurs extremely rarely. Even then, I believe the risk is limited to those with more direct contact than you would have:  if a wrestler had HIV, HBV, or HCV, and if that person's blood directly contaminated a fresh abrasion in the opponent, that might transmit the virus. But I am confident nobody else -- coaches, refs, etc are at risk from the sorts of exposure you describe. 

Could any of these viruses survived an hour of drying? Probably not, but I cannot say it is impossible. People speculate about how long these viruses may remain infectious as blood or other body fluids dry, with consensus that HIV probably doesn't remain infectious more than a few minutes. In other words, your "research" is correct to the best of my knowledge. But survival of the virus is not what's important. The important fact is that nobody in the world has ever been known to be infected in this manner, at least not with HIV. (We are not experts on blood borne transmission of the hepatitis viruses.)

You were not at risk and did not put your wife or anyone else at risk. My advice is a) to be immunized against hepatitis B, which is recommended for everyone anyway, then you can stop worrying about that one. Otherwise, just use common sense hygiene, i.e. wash with soap and water after wrestling events if you think you may have come into contact with blood. Finally, keep working with your therapist on your OCD. That's the health problem you have at the moment, not HIV or these other viruses.

Finally, please note the forum policy that prohibits repeated anxiety driven questions. Such questions have no value for other readers, one of our main goals; and ASHA does not want to keep accepting payment from compulsive searches for the same answers. Therefore, this will be your last thread on this topic. Any future ones will be deleted without reply and without refund of the posting fee. (And before you ask any follow-up question in this thread, please carefully re-read every word of this reply and of your other two threads. Anything else that comes to mind probably already has obvious answers.)

SO I can move on Bottom line: no risk, no worries, no need to test

Your bottom line is exactly right:  no risk, no worries, no need to test, and you can move on without giving these events another thought.

That completes the two follow-up comments and replies included with each question, and so concludes this thread. Do your best to keep dealing with the OCD; use common sense hygiene then forget the infection risks from blood borne viruses.
