Does alcohol sanitizer kills hiv virus. Actually one of my student had a scratch on lower lips and was bleeding which was very low. I mean to say blood was just on the top of scratch. He always used hiv hand to wipe of that blood and he came to me to get hiv copy signed, so while having this situation whenever he came to me I used hand sanitizer to kill virus if somehow some blood spot might touch my hand. But upon reading some article they say hand sanitizer are not effective or not good with visible blood or dirt. Can you please calrify me. After using hand sanitizer I used my finger to rub my eyes.
