How contagious is a cold sore?! I am worried I have HSV1

[Rad123]

Hi Everyone,

I’m worried I have HSV1. The other day my friend offered me a drag of his cigarette at a party, as I almost took a drag, I noticed he had a scabbed cold sore on his lip. Unfortunately the butt of the cigarette barely tapped my lip. But it did touch for 1 Sec. I am wondering if anyone else has transmitted HSV1 from sharing a cig or drink? I am very worried, and upset. It’s been 2 weeks, and no sores yet but I know i need to get tested after 4 weeks.

By the sounds of how you describe it, there's a very small chance of infection in this case.

Normally, transmission happens with rubbing/friction (think makeout session or sex) and isn't passed via inanimate objects.

You should be good.
