The way to transmission HIV

Question: 

Hi, my english is not good so firstly i'm so sorry about that.
I want to know what is the right way to transmission hiv. I have my hair cut a few day ago and barber cut into his finger and bleed. I don't know exactly which Wounds or scratches on my scalp.
As i find out, virus can be transmissed if the blood contact with wounds or scratches. But some forum about Hiv said that, hiv just can be transmissed from blood by sharing needles that you inject with.
So can you said to me if i have in a risk of hiv. and the right way to transmission virrus
Many thanks

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about how HIV transmission occurs, and specifically, your risk of acquiring HIV while getting a haircut by your barber and noticing that his finger was bleeding. From the information given, this scenario is determined to be No Risk (transmission of HIV is not possible in the given scenario).

The scenario mentioned above does not meet the three components of the HIV transmission equation(1). It does not satisfy the equation because:

  • HIV does not survive long outside the human body (such as on surfaces, or barber's scissors), and it cannot reproduce outside a human host.(2)

  • For the HIV transmission equation to be fully satisfied, the following 3 components must be met: a high risk activity (such as unprotected vaginal or anal intercourse, sharing needles), a body fluid (such as breast milk, semen, blood), AND direct access to the bloodstream (for example, through the vagina, anus and other musocal membranes).

This means that for the situation that you have described there was No Risk for you to acquire HIV. When your barber cut his hand, the blood was exposed to outside environmental conditions. We know that HIV does not survive long outside of the human body and cannot reproduce outside a human host (2). There also needs to be direct access to your bloodstream for transmission to occur. In the situation you described there was no direct access for your barber's blood to enter your bloodstream.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
