Oklahoma state Sen. Anthony Sykes (R) has proposed SB 733, which seeks to require testing to ensure couples are “not infected with syphilis or other communicable or infectious diseases” before they can get a marriage license. If people happen to be carrying an STD, they would need a doctor to sign off that their infection isn’t at a stage where they could pass it on to their partner.

What makes the move especially curious is that Oklahoma has one of the lowest rates of syphilis infection in the country.

Looking at the most recent U.S. Centers for Disease Control and Prevention data, from 2012, 84 people in the state were diagnosed with primary or secondary syphilis. This number pales in comparison to the 167 cases in Washington, D.C., and is even more pronounced when adjusted for population: In 2012, Oklahoma had 3.817 million residents to D.C.’s 635,040. As our graphs show—we compared the top five states with Oklahoma—this trend also rings true for several of the other major sexually transmitted infections.

Primary and secondary syphilis rates

Understandably, the bill is causing some concern around patient privacy.

“This new law would require you to file with the court clerk the results of this test, which the whole world could see,” Oklahoma attorney David Slane told News 9. “It seems to me that would violate people’s real privacy rights.”

Chlamydia rates

State Sen. Kyle Loveless (R), however, is a fan. He acknowledges that maybe preventing people with STDs from getting married is a tad excessive, but sees it as the perfect way of ensuring that Oklahomans are aware of their statuses.

“We have to look at that as a society whether we want people who have communicable diseases, they need to know if they have it, and I think this is a mechanism to provide them to do that,” he told News 9.

Gonorrhea rates

The proposed bill, if it were to pass, would go into effect on Nov. 1, 2015.
