My husband gave me Herpes2

My husband told me he tested positive for genital herpes 2. Yes he cheated. I was tested and was also positive. My question is this: Why was my score higher than his? Note that I have not had sex with anyone other than him in over 40 years and no i do not have any signs or symptoms of an outbreak. I’d appreciate any assistants i.e. web link, book etc.

your number was higher because yours was a more recent infection than his
