From The Herpes Handbook (2019)
Virus can be given off from the genital [ED NOTE: and oral] skin of both men and women with no sores, through microscopic breaks in the skin. This is called asymptomatic shedding of the virus; giving off the virus from the body with no apparent symptoms. The more sensitive our virus detection methods become, the more viral shedding we can identify. Shedding rates vary, based on location of virus and type of virus. The chart below is a guideline about how often shedding happens.
HSV-1 oral: 25% of days evaluated (91 days/year)
HSV-2 genital: 15-30% of days evaluated (55 to 110 days/year)
HSV-1 genital: 3-5% of days evaluated (11 to 18 days/year)
HSV-2 oral: 1% of days evaluated (4 days/year)
Note that GHSV-1 sheds about 3-10 times less frequently than GHSV-2 and 5-8 times less frequently than OHSV-1.
The use of Suppressive Therapy reduces shedding rates by around 50%.
Terri Warren writes on her website - www.westoverheights.com - that a new paper is about to be published that goes into more detail re: GHSV-1 shedding rates.
0-3 months from initial infection: 13.7%
4-24 months from initial infection: 7.1%
2 years + from infection: 1.3%
Note that someone with an established GHSV-1 infection (2 or more years old) sheds about 10 times less frequently than someone who has just had their initial outbreak.
