Sixty-five million people are living with STDs in the United States, and each year 15 million people contract one or more infections. Yet it's one of the most under-recognized health problems in the country. Here's a breakdown of just how surprisingly common they are.

1. 20 percent of people in the US has an STD.
2. 50 percent of sexually active youths will contract an STD by 25.
3. 20 percent of high-school girls have an STD.
4. 1 in 5 people over 12 have genital herpes as a result of type one or two herpes, though most genital herpes are from type two.
5. Only around 10 to 25 percent of people infected with genital herpes know they have it.
6. 15 new STDs are reported by porn actors and actresses each week.
7. Chlamydia is the most common STD. Women are three times more likely to be infected than men; however, it is thought to be due to the higher number of women screened for it.
8. HIV is the least common with 20,000 new cases per year.
