They would have to kiss your finger and rub there lips to force the virus into the nerve.
But I am talking about another person. Let's say that I am one of the people that doesn't have antibodies against herpes. SOMEONE ELSE touches his cold sore, then touches the wound on MY finger. Am I at rist, or is this too indirect?
Highly unlikely as you have antibodies that would help prevent it.
