Is there any chances of HIV transmission through used Potassium alum at barber shop ? I have one pimple maybe it cut while shaving from a new blade at barber shop from where some blood come out, barber immediately spray water on my face and applies that Potassium alum to stop it(this Potassium Alum was not used for about 5 to 10 minutes atleast), later I feared with thought that it was a used alum, So please help me for any chances of HIV transmission in this case. I freeking tensed. I can t even concentrate on any work. I asked on some other online place the doctor said there is no known issue but theoretically it is possible after, getting that response, I become too tensed, I am thinking that I will die soon. I am not afraid of death but I have Mom, Dad my little sister whom I have to support. I can t even apply my mind as per my little knowledge, not every blood contact transmit HIV. There should be enough amount of virus. I know that HIV virus can t live for long outside it dies but as per my knowledge virus never dies. Please clarify my doubts.
