Potent? Not really but contagious.
Is it always potent at the surface? Thanks so much
Much harder to spread but the virus can shed when no symptons are present. This means the virus is at the surface. For oral hsv1 this happens 10-15% of days on average.
If no cold sore is present is it hard to spread
Genital hsv1 is very rarely spread due to (as you know) few to no outbreaks and cery low shedding rates. This means you are umvery unlikely to spread genital hsv1.
Statistics aren't really known as there hasn't been studys done on genital hsv1. No money in it.
Cold sores are an outbreak and and very easy to spread when an active cold sore is present.
There is no stats on the percentage. Roughly half have oral hsv1 but no idea how many actually get cold sores. The stats are always ballpark as many people don't get cold sores or genital outbreaks that have hsv.
