 This age group made up 65% of chlamydia cases, and 53% of gonorrhea cases.Additionally, a study found that 15% of respondents in a sample of 2000 current and former American college students report never using a condom, and 4% only do so when their partner asks.Given college students fall within the age range of 15–24, and are more inclined to engage in casual sexual encounters without proper protection, post-secondary institutions hold a responsibility to ensure adequate STI screening and education prevention.
