To restate in different words:

"In developing countries, kids will get herpes from playing in the mud or other things. In the developed world, we incubate kids in sterile bedrooms, so their first exposure to this pathogen is during sexual activity."

This seems very elitist to me - having grown up in a first world country, where I played in the mud and hit things with sticks.

So, in poor countries all children are infected, which means as they age there's no risk to them as teenagers, because there's nothing risky about already having it and messing around with someone else that already has it.

Welcome to the wonderful world of spin doctoring.
