Maybe about a month ago, my mom was diagnosed with HSV 1 and 2, and it has been a hard time on my family. Our whole lifestyle has changed. We don't share food, drinks, or even kisses, because we are taking every measure to make sure my younger sister and myself don't contract it. Now, my mom was simply diagnosed with the disease, she's never had any outbreaks or those facial cold sores, neither has my dad (patient 0 in my household). My dad hasn't officially been tested or checked on, but he's the one that most likely contracted it from someone. But, just like my mother, he hasn't shown any signs of herpes. But I digress, my main question is: since neither of my parents have had any outbreaks, how likely is the transmission from just sharing a soda, a cigarette, or even giving a harmless kiss?
