Those numbers are probably in the ballpark, but it's for the average person. This paper (
https://pmc.ncbi.nlm.nih.gov/articles/instance/2809388/pdf/9593488.pdf) finds that HSV-2 prevalence in Japan is much higher in female sex workers than the average (like 5x if I'm reading right). Sure it was 1998 but has it changed drastically now?
Put that together with quotes like these from this thread:
That just seems totally counterintuitive since HSV-1 should show up for the majority of girls. Also, it seems like banning someone for a positive test would either end her career or just push her somewhere else.
These anecdotes I think give the false impression that infection is not widespread. But I think it's more likely that if people aren't contracting it from P4P, safe practices and low transmission likeliness is probably the reason, not that working girls just don't have it.
