blood is water soluble
Apr 12, 2011
Hi Dr. once day my friend gives me a glass of water for drinking. but on his finger small wound and cutes is present and small amount of fresh blood is given out from his finger. during taking a glass of water his this finger is put in to the water (as the blood is water soluble) and i drink that water if he was hiv infected then how many chances of hiv infection?
Response from Dr. McGowan
Not sure why you would drink the water if his hand was in it and how long has he had these sores? Not so much as a risk for HIV but just for general hygiene. Many other infections such as bacteria that can cause diarrhea or hepatitis can be spread much more easily than HIV.
In water the blood cells would break up since they burst in low salt fluids. Any HIV present would be diluted and would not offer a risk to you, especially if you have no open sores in your mouth. Of course if the water were grossly bloody that would be different.
