You were not at risk from this exposure! and do not need PEP. The virus is rendered inactive with change in temp. You say this is your friend? if you still worry ask him to test and end your worry.
Ok thank you for answering. 1 more question: Why can a person dont get infected with blood on his hand that touched his nose? Because the blood has to go inside his nose to become an hiv risk?
It is not a what if question. There was blood on his hand and i gave him a hand. It is normal for a person to touch his face once and while. i figured out that i cant touch my eye because a person has a normal reflex to close his eye while touching. I didnt pick my nose in a conversation but sometimes i touch it.
Therefore my question about the mucous membrame in the nose.
