Thanks for your question. If you have HIV infection you cannot transmit it back to yourself. So exposure to your own blood would not place you at any risk. Joe

BUT MY FOLLOW UP QUESTION IS THAT- this drop of hiv infected blood is of another hiv infected person. and my question is that can hiv transmit through my pimple by washing my face with this water present in the bucket?

Sorry for the confusion on my part.

No this would not be a risk for you since a drop of blood would become very dilute in the water and the cells and any organisms would not remain viable because they cannot survive in pure water (normally the body fluids have a balance of salts and water, in pure water the cells burst because the balance is lost). If the water were grossly bloody that may be a different circumstance.

Best, Joe
