This question might sound funny, but I do worry about it. I just went to a new barbershop to get a haircut and have some hair trimmed with a razor blade, and I did not see the barber change the blade. Suppose the previous customer had HIV. Would I be at risk? I forgot to check whether there was blood on the blade or not and I didn’t feel any cuts or wounds on my skin. I only experienced some burning sensation which normal after shaving. Would this pose a risk of HIV transmission? suppose there maybe a blood from previous client and it may infect to me. thanks you.

So, this is also not a risk even ? if there is blood on the razor blade from a previous customer (but if there is any, it must be very little—so little that the barber wouldn’t notice it). and I’m confused because I thought that if there is blood on the blade, it could infect the next customer through a cut that may occur.

But in my case, I didn’t notice any cuts or wounds, and I didn’t feel hurt. and From the inquiry above, do you still evaluate this as NO RISK and that NO TESTING is needed? and should I live my life without worry? thanks you Doctor
