My son was using a dryer located in a public toilet
Immediately after a bleeding boy from the hand used it
And my child felt that blood had entered him to browse through the air and a return that would come out of the dryer
Is there a risk for my child to be infected with HIV?
Thank you for your inquiry. From what we gather from the question, you were asking about the risk of your child acquiring HIV while using a public dryer. 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 transmission equation (1). It does not satisfy the equation because:
There must be direct access for HIV to enter the bloodstream. By direct access to the bloodstream, we mean through avenues such as the vagina, the anus or other mucous membranes.
HIV does not survive long outside the human body (such as on surfaces), and it cannot reproduce outside a human host (2).
This means that your child using a public dryer after you saw a bleeding boy using the same public dryer carries No Risk of your child acquiring HIV. The blood on the hand of the bleeding boy was outside of his body and thus subject to outside environmental influences. As indicated above, HIV does not survive long outside of the human body and it cannot reproduce outside of the human body (2), another reason why there is No Risk of your child acquiring HIV in this scenario. Also, there was also no direct access for the blood you saw on the bleeding boy's hand to enter your child's bloodstream.
Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health related questions.
