On a list of the most sexually diseased cities in the US, Lawton ranks at #50. That may be partially due to the presence of the Fort Sill Military Reservation. Active military bases tend to drive up STD rates in their host counties for all the reasons one would suspect.
Health officials are especially concerned about the rise of gonorrhea and syphilis. Syphilis was under control in the US a short decade ago, but it has made a comeback in recent years, mainly due to decreasing condom use. Gonorrhea is becoming resistant to the only medication available to treat it.
In 2016, the HIV prevalence rate in Comanche County was 181.2 per 100K people, almost equal to the Oklahoma rate of 183.8. Over 80% of HIV-positive individuals in Oklahoma are men.
That same year, Comanche County’s chlamydia rate was 895.3, well above Oklahoma’s rate of 548.4. The gonorrhea and (primary and secondary) syphilis rates were 324.1 and 11.2.
The Comanche County Health Department on Sheridan Rd provides STI testing. There are some nonprofits in the area that provide free STD testing, but only for HIV and hep C. And the Southwest Oklahoma Family Medicine Residency and Clinic tests for and treats HIV and hep C as well for a fee.
