A person can transmit HSV even if there are no open lesions. Though the risk is lower for a person taking antiviral medication. For information on this topic: https://www.who.int/news-room/fact-sheets/detail/herpes-simplex-virus

Daily valtrex suppression should be 500mg or 1000mg daily. If suppression is unsuccessful and experience a flare, I tell my patients to take the treatment dose, which is depends if it is genital or orolabial. Asymptomatic intermittent viral shedding can occur even in the absence of genital lesions
