HIV from invisible blood?

Is this possible? Yesterday a friend of mine cut the top of his hand then a few minutes later without tending to the cut touched my shoulder with his palm (opposite side to cut), the blood seemed to be staying in the area of the wound and did not see any blood on his palm or on my shoulder. I had a jumper and t shirt on but the skin beneath it was a bit damaged.

I know undamaged skin is perfect protection against the virus getting in but what about clothes?

I also when my hands are full scratch my face with my shoulder, the skin there is a bit red but mostly in tact slight damage from old exzcema still sort of viewable. This was a little bit after so imagine as it was in such a small quantity if there at all it would have died by then?

I would say your chances of getting anything from that contact is about zero. You would have to have direct blood to open wound contact to even START to worry about getting anything. Plus the fact that you had clothes on is additional protection. I think you're okay.

However, the next time your friend cuts himself, he needs to tend to that injury immediately to avoid any accidental contact.

HIV can live on surfaces for up to one hour, even though you may not be able to see the fluid. Your risk is minimal, but get tested, just be be safe.

I wouldn't worry if I were you. However just for peace of mind I would have a dr test me
