That’s a good question. Biologically, the result should be the same for people without or without symptoms but shedding in asymptomatic people who taken antivirals has not specifically been studied.
Oral herpes does shed more than genital HSV 1 so it is easier to transmit
If I had a partner who was truly negative for HSV 1 and I was positive for HSV 1, even without symptoms, and transmission was a concern, I would take daily antiviral medication
