A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

Pettis County Health Center, Sedalia's county health department, folds STI care into public health infrastructure: gonorrhea, chlamydia, syphilis, HIV, and hepatitis C testing, same-visit bacterial treatment, and HPV, hepatitis A, and hepatitis B vaccines, all on a sliding scale, with appointments required. Every service carries no fee.
The sliding scale at Pettis County Health Center runs all the way to no charge, every test, every vaccine, every treatment visit. Medicare is also accepted, meaning the fee structure accommodates a wide range of coverage situations without excluding anyone at either end.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Pettis County Health Center tests for hepatitis C. A blood-borne infection that often goes undetected without a specific prompt to test. TB testing is also available, making the infectious-disease scope here broader than a purely STI-focused panel.

Katy Trail Community Health in Sedalia runs on a sliding-scale fee structure, with HIV and hepatitis C testing free regardless of income, and accepts Medicaid and most insurance. Appointments are required for the full panel (HIV, syphilis, gonorrhea, chlamydia, hepatitis B and C, and TB) with same-visit treatment for bacterial infections.
Every service Katy Trail Community Health provides (testing, treatment, vaccines, PrEP, hepatitis management) is available at no cost, with sliding scale covering what insurance doesn't. The billing infrastructure is built to absorb the full scope of care, so nothing on the service list becomes a separate, out-of-pocket transaction.
Spanish-language care at Katy Trail Community Health is delivered directly through clinical and counseling staff: meaning sexual health history, medication adherence education, and treatment planning all happen in Spanish without a relay layer. That staffing distinction matters for PrEP counseling and STI follow-up, where precision in the conversation is part of the clinical work.
When PrEP or PEP isn't available at a testing site, patients leave with instructions to find a prescriber. Adding days or weeks to a time-sensitive decision. Katy Trail Community Health prescribes and manages both on-site, and carries PrEP specifically for uninsured patients, so prevention doesn't stall between a test result and a separate provider.

STD stats & rates
How reported STI rates in Pettis County, the county that includes Smithton, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~27% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#40 of 115 Missouri counties for chlamydia, a higher rate than 65% of the state
| Infection | Pettis County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 296.3 129 cases ▼ 41% | 498.6 | 492.2 |
| Gonorrhea | 48.2 21 cases ▼ 76% | 201.9 | 179.5 |
| Syphilis (P&S) | 13.8 6 cases ▼ 36% | 21.5 | 15.8 |
| Syphilis (early) | 9.2 4 cases ▼ 26% | 12.4 | 16 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in Pettis County, chlamydia has fallen from 404.8 to 296.3 per 100,000 (27%), gonorrhea has fallen from 139.6 to 48.2 per 100,000 (65%), and P&S syphilis has risen from 2.3 to 13.8 per 100,000 (500%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Pettis County.
Local HIV snapshot
Federal priority area: Missouri is one of the U.S. jurisdictions prioritized under the Ending the HIV Epidemic initiative: targeted federal funding to expand local HIV testing, PrEP, and prevention.
Pettis County HIV care continuum (2020)
Pettis County recorded 19.9 new HIV diagnoses per 100,000 (2020), against 10.6 statewide and 13.7 nationally. Among Pettis County residents living with HIV, 75.8% are in care · 69.7% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Pettis County tests for syphilis.

Data & references
Local context
For young adults here who are dating, newly partnered, or simply taking their health seriously for the first time, that calculation is real. The county's STI patterns reflect what happens when routine care requires deliberate planning rather than a casual stop. The town's strong homeownership culture and household size, most residents live in family-structured homes with partners or children under the same roof, can make private, individual health decisions feel logistically complicated. At the same time, the modest typical rent means cost pressure, while real, isn't the only barrier.
For the roughly one in four households earning well above the median, out-of-pocket fees are less of an obstacle; for everyone else, the fee structures listed in the clinic cards matter more than they might in a wealthier zip code. Pettis County's rural spread is exactly why options listed here represent genuine range, not redundancy: different hours, different fee tiers, and different distances along the highway out of town. That variety means a resident on the south side of Smithton and someone closer to the county's rural edge can each find a realistic fit.

Two things that actually depend on Missouri law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In Missouri, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Missouri permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
