sir , 

Welcome to our Forum.  We get many questions from clients who are worried about the risk of HIV or hepatitis virus infection from contact with fresh cuts or blood or secretions from an infected person which are aerosolized and ingested through the eyes or nose.  Despite a possible theoretical risk, the FACT is there are no proven instances in which someone has become infected in that way.  Thus if I were you, I would not worry- I suspect that others in your class are unlikely to have HIV or hepatitis and even if someone did, there is no proven risk.  I hope this comment is helpful to you.  EWH---

sir, 

You have misread the comments on this site you refer to and the incidents that you may have read about in laboratory accidents are very rare and when they occurred, resulted from exposure to very high concentration of virus (far higher than occur with natural infections).  Other than the sorts of laboratory accidents you refer to, I an unaware of ANY occasions in which persons have acquired HIV from aerosols or splashes of the sort you describe- not in any patients of mine, not at any scientific meetings and not in the medical literature.  The blink reflex would rapidly close the eye and prevent infection when a splash would occur.  Your concern is just not a realistic concern and I would urge you not to let this worry you or prevent you from pursuing martial arts training if you wish to do so.  EWH

thank you sir for clearing this , i thought laboratory accidents happened from test tube where blood collected .test tube contains small amount of blood. so. you are saying there was large amount of blood in laboratory  that caused hiv . how much blood ?? suppose i had accident , i was exposed to large  amount of blood . so can i have the chance of getting hiv??

 You seem to not believe me when I tell you that you are not at risk.  The  infections originating from laboratory accidents splashing material into the eye do not originate from blood exposure but from exposure to high concentration of cultured virus.  The sorts of exposures you have spoken about do not constitute a risk.    Blood exposures lead to infection when the blood is injected into tissue, not from splashes or touching.   Further it is not the amount of blood a person is exposed to but the amount of virus that is present in the blood that determines risk for infection.  This ( the amount of virus present) varies greatly from person to person depending on their stage of disease and whether or not they have been treated. Once again however I must emphasize to you that the sorts of exposures you describe are not a risk for HIV.---
