Afraid I might stepped on a syringe some weeks ago?

Or afraid it touched my arm. Looked like there was a little red hole, very tiny. But it didn't bleed.

Hypothetically, would this be enough to transmit the disease, or would it have to bleed? Not even sure it was a needle / syringe though..

Thnx

I mean, ofc, if there is any risk of getting hiv from it?
