Some other possibilities (guesses):
- Banning of transfats
- Better dietary and fitness practices in general
- People getting on daily antivirals if they have HSV

That's not happening in Europe, only Americans are weird about HSV. Most Europeans ignore it and don't make a big thing out of it.
Roughly 60% population have HSV-1 (and 10% HSV-2). I don't think that the percentage of people getting daily antivirals is the same.
