In 2022, Oklahoma saw some of the highest rates of sexually transmitted infections in the nation, specifically in syphilis and chlamydia. Now in 2024, the state has made great strides and Oklahoma is seeing improvement in trends.

According to data provided by the Centers for Disease Control and Prevention, the United States saw a decrease in cases for a majority of notifiable STIs between 2023 and 2024.

Sexually transmitted infections, such as syphilis and gonorrhea, are notifiable diseases, which means health providers are required by law to report positive tests to state or local public health officials. This data is then used by officials to track and prevent outbreaks. However, some STIs can remain asymptomatic, and those not regularly getting tested can unknowingly pass on an infection to a partner.

Here’s a look at how Oklahoma has progressed in STI rates through 2024:

Chlamydia 

Oklahoma saw 18,729 cases of chlamydia, the state’s most prevalent STI, from the start of 2023 to mid-December. This places the state near the top 10 states in the nation for highest Chlamydia rates at No. 11. 

According to CDC data, the number of cases in Oklahoma decreased 44% in 2024 to 10,461 statewide. This moves Oklahoma to the middle of the nation’s positivity rates and the lowest in the region, which includes Arkansas, Louisiana and Texas.

The drop is not singular to Oklahoma, either. All states, except South Carolina, saw a decrease in new cases, with over a quarter of a million fewer cases in 2024.

Syphilis

Oklahoma was previously a leader in syphilis cases across the nation in 2022. But new Oklahoma cases have been cut in half compared to just last year. 

The CDC reports that in 2023 there were 1,112 primary and secondary cases of the infection and 78 for the congenital variant. However, by the end of 2024, both numbers had dropped substantially. Congenital syphilis cases dropped to 50 cases throughout the year, while the primary and secondary cases dropped over 50% to 517 total cases.

The nation’s year-end data also reflects this as well. Only four states weren’t a part of the national decrease. There were almost 20,000 fewer cases in 2024 than in 2023 for primary and secondary syphilis and roughly 1,200 fewer cases for the genital variant.

Gonorrhea

Similarly, the nation’s gonorrhea cases have decreased by over 100,000, with all states reporting lower numbers than in 2023. Oklahoma reported 6,774 new infections to the CDC in 2023 and will report 3,842 new cases in 2024. 

Similar decreases were seen around the nation, with the total number of cases dropping from almost 600,000 in 2023 to 484,453 in 2024.

Hepatitis B

The CDC tracks three different forms of Hepatitis B: acute, chronic, and perinatal.

Acute Hepatitis B is the only CDC-reported STD that saw an increase nationwide, increasing about 150 cases. Oklahoma, however, did not contribute to the rise as the state fell from 19 cases to 4 throughout 2024.

The CDC has not published the nation’s chronic Hepatitis B cases for 2023. In Oklahoma, there were 213 reported positive cases in 2023. For comparison, the country reported 263 new cases just in the week ending Dec. 21, 2024. The Sooner state sits in the lower half of the country for total cases, while the country reaches 17,864.

Oklahoma did not contribute to any of the nation’s 7 Perinatal cases.
