Results of a national study indicate that genital herpes infection is common in the United States. Across this nation, at least 45 million people ages 12 and older, or one out of five adolescents and adults, have had genital HSV infection. In the past decade, the percent of American citizens with genital herpes infection has decreased. This is good news.
Genital HSV-2 infection is more common in women. Approximately one out of four women have genital herpes. Almost one out of eight men have genital herpes. This statistical difference may be due to male-to-female transmission being more likely than female-to-male transmission.
