Feel and scratched my knee on sidewalk

[Quickquestio321]

I feel badly and scratched my knee on the ground, my jeans got torn and the scratch was quite bad and scanned over, is there anyway that I could have picked up a blood born virus like hiv or hep,

There's nothing to add.
Malbat is 100% right.

[Quickquestio321]

Thank you malbat, do the other contributors here have the same opinion?

[Quickquestio321]

Last question and I know it's unlikely and hypothetical, but let's say there was hiv blood on the spot on the ground when I gashed my knee, it was friction related and tooth a layer of skin about 2 inches by 2 inches.

Any bodily fluids, once exposed to air, is not infectious anymore. You are safe to move on. You had no risk.

[Quickquestio321]

Regardless if there was anything on the ground or not?

[malbat]

Yup. As an adult, Hiv is transmitted by having unprotected vaginal/anal sex and by sharing iv drug needles with other drug users. That's all.

[malbat]

You don't get hiv in the manner you describe. You had no risk.

I didn't check the ground if it was "clean"
