How big does your cut have to be to transmit HIV if you touched HIV infected blood? Theoretically, if someone had shallow, 2cm (length) cut on their palm of their hand and they touched HIV infected blood and it got on their cut, is that enough to transmit the virus.
Or does the cut have to be deeper and the virus needs to enter the bloodstream? Also, does alot of blood need to be exchanged to infect?
Thanks, last question to easy my worries on an environmental surface (I know... no risk, but i would like to know the scenario that WOULD lead to a probable transmission. Once again thanks for all the support this forum has showed me.
