>Figure 1. Age-adjusted prevalence of herpes simplex virus type 1 among persons aged 14–49, by age group, sex, and race and Hispanic origin: United States, 2015–2016
So where exactly are they getting this data from?"
Seems like bullshit.
I've seen plenty of people lick their fingers to count money/ flip pages and moms/ female teachers kiss kids on their foreheads to check if they're sick.
If it were so prevalent, then people wouldn't do those things.
