It IS dangerous on the lips, it's a different vitus to genital herpes and it can be passed on without kissing as the skin can shed, or be passed on via hands if touched.
Now I'm not saying this to scare monger, but this lady is a personal friend of mine and has made a lot of effort to spread awareness.

But please read, please be aware, please spread the information.
