Thomas County Health Department, Colby's public health department, folds STI testing into its broader public health infrastructure: gonorrhea, chlamydia, syphilis, HIV, and more on a sliding-scale fee, with same-visit treatment for bacterial infections by appointment, and Title X family planning, including confidential services for minors.
Thomas County Health Department operates under Title X, the federal family planning program that legally mandates confidential services for minors. Meaning those services are protected by statute, not departmental policy. That designation also sustains the sliding-scale fee structure that applies to everyone, regardless of coverage.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Thomas County Health Department runs herpes, hepatitis B, and hepatitis C testing within the same appointment. Each requires its own specimen collection and laboratory analysis, the expanded panel is built into the clinic's standing test menu, not requested as an add-on.

STD stats & rates
How reported STI rates in Thomas County, the county that includes Gem, compare with Kansas 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.
#66 of 105 Kansas counties for chlamydia, a higher rate than 37% of the state

| Gonorrhea | 25.4 2 cases ▼ 82% | 144 | 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 Thomas County, chlamydia has fallen from 403.5 to 165.3 per 100,000 (59%), and gonorrhea has fallen from 126.1 to 25.4 per 100,000 (80%).

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 Thomas County.
Local HIV snapshot
Thomas County HIV care continuum (2023)
Thomas County recorded 0 new HIV diagnoses per 100,000 (2023), against 6.1 statewide and 13.7 nationally. 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 Thomas County tests for syphilis.

Local resources & officials
Data & references
Local context
Gem sits at the end of a real drive (not a quick errand, but the kind of trip that takes planning) and for younger adults here who are still sorting out relationships and routines, that distance is the first thing that shapes whether screening happens at all. Thomas County's rural spread means no clinic is around the corner, and in a place where nearly everyone owns their home rather than cycling through rentals, the population has a settled, long-term character: households are larger than the national average, and a sizable share of high earners suggests many residents run farm operations or small businesses with schedules that don't bend easily to a weekday appointment. That workforce reality (more than six in ten residents active in the labor force, with some carrying their own ventures) means testing has to compete with long workdays and limited flexibility.
People in their late teens and twenties make up a substantial slice of this community, and they're at exactly the life stage when routine screening tends to fall off the calendar, especially when the nearest option requires gassing up and committing an afternoon. That's where options listed on this page matter: the range covers different hours, cost structures, and distances, so someone in Gem can find the combination that fits the highway-out-of-town reality of Thomas County without defaulting to skipping it altogether.
Getting there

Two things that actually depend on Kansas 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 Kansas, a minor of any age can consent to confidential STI testing and treatment on their own, no parental permission is required.
Kansas 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.
