The viruses listed by parent aren't spread sexually, though they are all herpes viruses.

EBV is also known as HSV-4 and gets to 60% plus prevalence in children, 90% in US adults. If there are populations with especially low prevalence I'm not aware of it.

HSV-1 which causes mouth cold sores is present in 50-80% of people, also easily acquired in childhood. Only 20-40% of infected people get cold sores so most infected people don't realize they have it.

Chicken pox/shingles is also a type of herpes virus with well known massive prevalence!

Genital herpes is just one of many types of herpes viruses that affect humans.

Oops, I thought the 90% was referring to HPV.
