No one treats for HSV1 ever unless you have a bad active outbreak.

Worldwide, ∼90% of people have one or both viruses. HSV-1 is the more prevalent virus, with 65% of persons in the United States having antibodies to HSV-1 (Xu et al., 2002). The epidemiology in Europe is similar, with at least half of the population seropositive for HSV-1. In the developing world, HSV-1 is almost universal, and usually acquired from intimate contact with family in early childhood

2/3 of the population UNDER 50 have some form of HSV, but virtually every person autopsied that died over the age of 60 will have HSV-1. It’s THAT common. That’s why they don’t test.
