Thank you both for the help! My mind is now more comfortable! :)
Doesn't contact between wounds transmit the desease though?
I asked the same in another place and they told me it was possible if the blood mixed, but since the punch was a snap yeah I also tought it was zero risk, but I just wanted to confirm. Thank you for your fast reply!
Zero risk. HIV is only transmitted by unprotected vaginal, anal sex and by sharing of needles.
Regardless if the person had HIV or not.
