We don’t know the shedding rate of people with oral HSV 1 and no symptoms.
We do know that people who have genital SHV 1 and have been infected for at least two years shed virus on about 4 days out of the year.
Once a person has been identified as being infected with some strain of HSV, many do go on to recognized symptoms that previously they had missed. About 70% of those infected with HSV 1 by antibody test would say that they don’t have symptoms in either location.
