If the rates of transmission are so low (8 percent for year with infected partner or lower), why/how do 40-50 million people have genital herpes?

Sex and Math: Approximately 1 in 5 or 6 US adults and teens have HSV type 2 infections and do not know it. According to the CDC 776, 000 in the US get new infections yearly. So a lot of people are going around having unprotected sex spreading a virus without knowledge. Question the 8 percent per year rate.? Sex partners need to get blood tests before becoming intimate, use condom, if + take antivirals.
