Sexually transmitted diseases (STDs) are becoming more common across the United States and right here in Ohio. The federal Centers for Disease Control and Prevention recently reported that for the fourth straight year, in 2017, prevalence of chlamydia, gonorrhea, and primary and secondary syphilis climbed in the U.S., and that trend largely tracks with increases in the same STDs in Ohio.
Where does Ohio rank nationally when it comes to STD prevalence, how have those diseases changed in Ohio in the past few years, and where in our state are STDs most common? To better understand the state of sexual health in Ohio, let’s look at data from the CDC and the Ohio Department of Health.
Note: Ohio recently published its 2018 STD data for chlamydia, gonorrhea, and primary and secondary syphilis, but data for the remainder of the states have yet to be published by the CDC, so in some cases, we are comparing 2018 data for Ohio to 2017 data for other states. In the case of chlamydia and gonorrhea, Ohio’s rates have increased, though not by very dramatic amounts. Still, when the full national dataset is released, it’s possible the state’s rankings could shift here or there.
Chlamydia Rates in Ohio
Ohio ranks eighth out of all states in sheer numbers of chlamydia infections, but after adjusting for population size, the state falls slightly, though it’s still in the top 20 for chlamydia infection rate.

In addition to its place among the 20 states with the highest rates of chlamydia, Ohio has seen prevalence of the disease rise over the past several years, climbing nearly 20% since 2012.

Ohio has the second-highest rate of chlamydia in the Midwest.

Gonorrhea Rates in Ohio
Ohio’s population-adjusted rate of gonorrhea infections is ninth in the nation, and the state reported more than 25,000 cases in 2018.
Gonorrhea infections per 100,000 people
Gonorrhea is becoming more common all across the country, and the same is true in Ohio, where the gonorrhea rate has gone up by more than 50% since 2012.

Ohio has the highest rate of gonorrhea in the Midwest, just ahead of Missouri, though, again, it’s important to note that the state’s placement may change once every other state in the region releases its 2018 data.

Syphilis Rates in Ohio
Ohio’s rate of incidents of primary and secondary syphilis is near the middle nationally, and the 2018 data shows a substantial decline from 2017.
Primary and secondary syphilis infections per 100,000 people, top 30
While the state’s primary and secondary syphilis rate fell between 2017 and 2018, overall it’s nearly doubled since 2012.
Ohio primary and secondary syphilis rate by year (cases per 100,000 people)
Ohio has the third-highest rate of primary and secondary syphilis infections in the Midwest, placing just ahead of North Dakota.

HIV & Other STD Rates in Ohio
More than 1,000 people were newly diagnosed with HIV in Ohio in 2017 (the most recent available year for HIV data), an increase of about 4% from 2016. The state’s HIV infection rate of 8.8 per 100,000 people is higher than the national median. See best HIV test options.
Hepatitis B & C
Ohio has some of the highest rates of acute infections of both hepatitis B and hepatitis C and rates of both have gone up since the rates observed a few years ago. Ohio ranks sixth overall for hep B infections with a rate of 2.6 per 100,000, more than twice the national rate and a 73% increase between 2013 and 2016, though the rate dipped between 2015 and 2016. For acute hep C cases, Ohio has the 13th highest rate in the U.S. at 1.6 per 100,000 people, about 38% higher than the national rate. The state’s hep C infection rate has increased more than 16-fold since 2012. See best HIV test options.
The most common STD in the world, human papillomavirus (HPV) also happens to be the primary cause of several types of cancers, including cervical, penile, anal and vulvar cancer. HPV-related cancer rates are higher than the national median in Ohio (12.7 per 100,000 vs. 11.7 per 100,000). See best HPV test options.
STDs in Ohio Cities & Counties
While Ohio varies in terms of prevalence of various STDs, certain areas of the state are more STD-prone than others, with Ohio’s metro areas accounting for an outsized percentage of chlamydia, gonorrhea and syphilis.
More than a third of all chlamydia infections in Ohio in 2018 occurred in Cincinnati, Cleveland or Columbus.

Almost 1 in 5 gonorrhea cases in Ohio in 2018 were diagnosed in the city of Columbus.

Primary and secondary syphilis
Columbus accounted for nearly one-quarter of all diagnoses of primary or secondary syphilis in Ohio in 2018.

Most sexually transmitted diseases are becoming more common in Ohio, but history tells us that most people who contract many of the most common STDs are never diagnosed and so they pass those diseases along to their sexual partners without even knowing. Depending on your risk level, it can be scary to think about finding out your STD status, but the good news is that most common STDs are easily treated and even the ones that can’t be cured outright often can be something you can live with.

Note: Some states have published more recent data for chlamydia, gonorrhea, and primary and secondary syphilis. For states in which that’s the case, we have substituted the individual state data for 2018 and used that in our rankings, while other states’ rankings are based on 2017 numbers. In some cases, we assume that when the full national dataset is published by the CDC, states’ positions relative to other states will change some, though those changes are unlikely to be dramatic, since the CDC data comes from the states.
