Hi!
Recently i started thinking about wounds and hiv. Why hiv cannot be transmitted through very small abrasions or wounds? I mean wounds which bleed very little or only when you push skin around them hardly. I know hiv dies very quickly in air, but why superficial wound can't make access to bloodstream? Tiny blood vessels and cappilaries are broken and can lead virus to bloodstream? I think about it because i often have small injuries on hands and if infected blood exposed exactly on the fresh but very superficial wound, then why it is not risk?

Hello and thank you for your interesting question.

I cannot say that it would be absolutely impossible for the virus to pass through a small abrasion or wound but what is known is that superficial cuts or abrasions have not been found to be the means for transmission. Even a heavily bleeding wound has not been reported to be the means for HIV to access the body. The hand is a dry surface and small abrasions start to heal fairly quickly. You are correct that the virus loses much of its ability to be passed along once it is exposed to air, further reducing the risk to you through small wounds on the hands.

I hope this helps to address your concern. If you have other HIV related questions please do not hesitate to contact the Helpline again.

All the best,

Marnelle
