You can get viruses but you wont get hiv
Their are many viruses you can get but of your cut wounds had already healed you wont be at any risk of getting any viruses just place your hand in a warm pot of water for 10mins and everything will be already
I didn't have any open cuts or wounds on my feet but I'm not sure if I aquired a small cut I couldn't see or feel while I was walking on the beach with all the broken shells. So that's my fear. That I had a small brand new cut and then stepped in a strangers blood on the sand. I'm sure I'm being overly paranoid but that kind of stuff scares me. I'm hoping between the combinaton of the sand and salt and sun any viruses wouldn't stand a great chance in staying alive.
No it doesn't stand a chance but u should go get a blood test and check for everything just to be sure nothing major to worry about
