Bothwell Regional Health Center in Sedalia tests for HIV, syphilis, gonorrhea, chlamydia, herpes, and hepatitis A, B, and C on a sliding-scale fee accepted by Medicaid, Medicare, and private insurance. Appointments are required, and bacterial STIs can be treated the same visit.
Bothwell tests for herpes and hepatitis A, B, and C in addition to HIV, syphilis, gonorrhea, and chlamydia. Meaning a single appointment can surface infections that a narrower panel would leave undetected and unmanaged.
Without access to both PrEP and PEP at the same site where you test, prevention can stall: one gap in coverage, one delayed prescription, and the window closes. Bothwell carries both, so the path from testing to an active prevention plan doesn't depend on a second provider.

STD stats & rates
How reported STI rates in Johnson County, the county that includes Knob Noster, compare with Missouri and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~40% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#17 of 115 Missouri counties for chlamydia, a higher rate than 85% of the state
| Infection | Johnson County | Missouri | United States |
|---|---|---|---|
| Chlamydia | 438.5 241 cases ▼ 12% | 498.6 | 492.2 |
| Gonorrhea | 60 33 cases ▼ 70% | 201.9 | 179.5 |

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 Johnson County, chlamydia has fallen from 718.3 to 438.5 per 100,000 (39%), gonorrhea has fallen from 211.1 to 60 per 100,000 (72%), and P&S syphilis has risen from 5.6 to 7.3 per 100,000 (30%).

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 Johnson County.

Johnson County HIV care continuum (2023)
Among Johnson County residents living with HIV, 66% are in care · 49.1% 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 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 Johnson County tests for syphilis.

Data & references
Local context
Highway 50 cuts through Knob Noster quickly enough that it can feel like the town barely registers on a drive, but for residents, that same stretch is often the start of a longer trip to reach any significant services. With the majority of households here renting rather than owning, and typical rents sitting low enough to signal real budget discipline, an unexpected medical bill can genuinely reshape a month. That cost reality shapes how people weigh optional-feeling appointments, including screening they know they should probably schedule. The workforce here is notably active, most working-age adults are employed and unemployment is nearly nonexistent, which means schedules are full, not free.
For younger adults still building their lives, often among the larger households common in Knob Noster, a clinic visit competes with real shift commitments. The options listed on this page serve the area in and around Knob Noster, and several offer extended or flexible hours worth checking against an actual work schedule before assuming a visit won't fit. Nearly half of adults here are married, and households tend to run larger than the national average. Routine screening fits those life stages too, it's part of what couples and families do to stay ahead of things, not a signal that something has already gone wrong.
Getting there
At 5.82/20 on the EPA walkability index, day-to-day errands in Knob Noster generally mean driving: plan on a car or rideshare to reach a clinic, and check each listing's hours and phone before you go.

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.
