Sexually transmitted infection (STI) incidence is on the rise in the United States. The increase is especially pronounced in adolescents (15–24 years of age). Despite making up only a quarter of the population, adolescents account for approximately half of new STIs in the United States every year.
It's not all of the teens' fault, but one way or another stds are on the rise. Whether it is a one-night stand, someone didn't know they had a Std or from other reasons, the stds transfer from one to another.
