Are you asking if shedding shows up when someone's immunity is low?
Maybe. Shedding happens when immunity is fine - it's part of the disease process. Oral hsv1 sheds, on average, 25% of days a year, outside of outbreaks. That varies from person to person, obviously, but everyone with herpes sheds.
Are you asking about the eye concern?
Your other question, which I am adding to this one, is:
"Can genital hsv1 be transferred to the eye of someone who is negative for both 1&2 ( confirmed prior via blood tests), if that person got vaginal secretions on their finger and rubbed their eye shortly afterwards?
Is herpes virus likely to be in vaginal fluid? (15+ years genital hsv1)"
You've had ghsv1 for 15+ years. You are probably shedding 1%, or 4 days a year, outside of outbreaks. Do you get outbreaks?
It would be HIGHLY unlikely for you to ever transmit it.
