Dear Expert,
Thanks for the great work that you are doing. I visited a barbershop today for hair cut and when he was combing my hair he caused a small cut/scratch, it bled very little - I saw one small smeared drop of blood when I got home-. I am very worried now, since he might cut the previous customer with the same brush. What is the risk of HIV transmission if the brush wasn't used for at least 5 mins.
Your reply is highly appreciated.
Thanks you for your time.
