The Most Common STD in College Students (And What to Do About It)

HPV, or human papillomavirus, is the most common sexually transmitted infection among college students in the United States. The CDC estimates that nearly 80 million Americans are currently infected, and young adults between 18 and 26 account for a disproportionately high share of new cases each year. Knowing this is the first step toward protecting yourself.

HPV spreads through skin-to-skin genital contact, not just penetrative sex. That means condoms, while helpful, do not eliminate the risk entirely. Most people who have HPV never develop symptoms and never know they have it, which is exactly why it spreads so easily on college campuses.

There are more than 100 strains of HPV. Most clear on their own within one to two years without causing any health problems. However, certain high-risk strains can lead to cervical, anal, throat, or penile cancers if left undetected. Low-risk strains can cause genital warts. Regular screening is what catches the difference early.

Here is what you can do right now. If you were assigned female at birth, the CDC recommends a Pap smear every three years starting at age 21, or an HPV co-test every five years starting at age 30. If you are between 9 and 26, the HPV vaccine series is highly effective at preventing the most dangerous strains. Talk to a licensed physician about whether catching up on vaccination makes sense for you.

For people assigned male at birth, there is currently no FDA-approved HPV screening test. That makes vaccination even more important, since it is often the only proactive layer of protection available. The CDC recommends the vaccine through age 26 for everyone, and shared decision-making with a doctor for adults ages 27 to 45.

Chlamydia is the second most commonly reported STD among college students, according to CDC surveillance data. It often has no symptoms either, making routine testing essential regardless of how you feel. Testing for chlamydia is simple, fast, and can be done without a clinic visit or insurance involvement.

The most actionable thing you can take from this: do not wait for symptoms to decide whether to test. Most common STDs in this age group produce no obvious signs. A routine panel once or twice a year, combined with vaccination if you are eligible, gives you real information and real peace of mind.

Frequently Asked Questions

What is the most common STD in college students?

HPV (human papillomavirus) is the most common STD among college students, with the CDC estimating around 80 million Americans currently infected. Chlamydia is the most commonly reported bacterial STD in this age group.

Can you have HPV and not know it?

Yes. Most people with HPV have no symptoms and no visible signs, which is why it spreads so easily. The only way to know your status for certain is through regular screening, such as a Pap smear or HPV co-test for those with a cervix.

Does the HPV vaccine work if you are already sexually active?

Yes. The HPV vaccine can still protect you against strains you have not yet been exposed to, even if you are already sexually active. The CDC recommends it through age 26 for everyone.

How often should college students get tested for STDs?

The CDC recommends sexually active people under 25 get tested for chlamydia and gonorrhea at least once a year. More frequent testing may make sense depending on the number of partners and other individual factors.

Is STD testing confidential if you are on your parents’ insurance?

Testing through insurance can generate an Explanation of Benefits that a policyholder may see. Choosing a private, out-of-pocket testing option keeps your results off your insurance record entirely.
