Just checked, seems that in english there's a name difference between genital herpes and herpes zoster, to which is normally refered as shingles.
The later one is spread to 98% of the US population (
source), this is why i find this topic so...redundant. Herpes is more "popular" than nearly everything on this planet.
But seems that most people are thinking of genital herpes, which is only common in 16% of the US population (
source).
