STD's by State

United States of STDs - Exploring the Rates of Sexually Transmitted Diseases in America

You and an attractive someone both swipe right and are now meeting up for drinks and potentially more.

You have to ask yourself, though – if it ends up going well, what exactly are your odds of taking home something other than a great hook-up story?

From where you live to how old you are and the number of sexual partners you’ve had, we added up the odds of you walking away with an STD. With more than 19 million new cases of STDs in the U.S. every year, it’s important to understand where the risk lies. We explored the rates of chlamydia, gonorrhea, and syphilis, which have federally funded programs for prevention, and have seen increases of 5.9%, 12.8%, and 19%, respectively, over the previous year of the CDC report. Continue reading to see what we learned.

Rates of STDs Across the U.S.

Rates by State

If you live in Washington, D.C., the good news is that you live in the nation's capital and have quick access to some of the most exciting educational opportunities the country has to offer. The bad news, unfortunately, is that the odds of contracting syphilis, chlamydia, and gonorrhea are not exactly in your favor. That and the traffic in D.C. is terrible.

Like it or not, according to the CDC, rates of two of these sexually transmitted diseases are highest in D.C. Specifically, your chance of contracting gonorrhea is nearly double (416.2 cases per 100,000 residents) that of the next highest-rated state (221.1 cases per 100,000 residents).

Louisiana tops the list as the riskiest state for encountering syphilis. This state had the second-highest rate of gonorrhea and the third-highest rate of chlamydia.

Other Southern states like North Carolina, South Carolina, Mississippi, and Georgia also had some of the highest rates of these STDs. If you’re passing through these areas, comfort food might be a safe bet but consider passing on the unprotected sex.

People Most Likely to Have an STD

Age Groups and STDs

When considering the odds of contracting an STD, men and women between the ages of 15 and 29 have the highest rates of occurrences.

We found the odds of contracting chlamydia or gonorrhea were exponentially higher during these young years compared to those who were older. For chlamydia, there were over 2,500 cases of this uncomfortable bacterial infection for every 100,000 people. That’s more than a 1 in 40 chance you or someone you may be spending close time with has contracted this “silent” infection.

Sexually Transmitted Odds

Sexually Transmitted Odds

Think of it like playing multiple hands at poker, or putting down extra bets on the roulette table – the more you play, the better your odds of winning. Or losing in the case of STDs.

Women had worse odds when it came to chlamydia, with more than double the likelihood of contracting it from just one partner – and their odds only got worse as that number expanded. People sleeping with more than 200 different female love buddies had almost a three out of four chance of contracting chlamydia, compared to those who sleep with men, where they were less than half as likely to get the itching, burning, and the discomfort that is chlamydia.

While not as common, at just one sexual partner people sleeping with either gender had just about the same chance of encountering gonorrhea. As the number of partners increases, you see that those with male sexual partners have a higher risk.

A Game You Might Want to Win

Playing the odds with STDs is like playing a game you really don’t want to win. Take our word for it. We recommend getting tested and then switching your attention to games with prizes you wouldn’t mind telling your friends about.

Come play with us at We have all your favorite games with bonuses and payout rates worth bragging about. And unlike a hookup who hasn’t been tested for unfortunate STDs, we’ll only introduce you to sites you can trust.


We used the CDC Surveillance report on STDs to explore STD rates per 100,000 residents. To calculate accumulating risk, we used the formula for cumulative binomial probabilities which can be found here.
